cmake version 2.8.12.1
------------------------------------------------------------------------------
Name

  cmake - Cross-Platform Makefile Generator.

------------------------------------------------------------------------------
Usage

  cmake [options] <path-to-source>
  cmake [options] <path-to-existing-build>

------------------------------------------------------------------------------
Description

The "cmake" executable is the CMake command-line interface.  It may be used
to configure projects in scripts.  Project configuration settings may be
specified on the command line with the -D option.  The -i option will cause
cmake to interactively prompt for such settings.

CMake is a cross-platform build system generator.  Projects specify their
build process with platform-independent CMake listfiles included in each
directory of a source tree with the name CMakeLists.txt.  Users build a
project by using CMake to generate a build system for a native tool on their
platform.

------------------------------------------------------------------------------
Options

  -C <initial-cache>
       Pre-load a script to populate the cache.

       When cmake is first run in an empty build tree, it creates a
       CMakeCache.txt file and populates it with customizable settings for
       the project.  This option may be used to specify a file from which to
       load cache entries before the first pass through the project's cmake
       listfiles.  The loaded entries take priority over the project's
       default values.  The given file should be a CMake script containing
       SET commands that use the CACHE option, not a cache-format file.

  -D <var>:<type>=<value>
       Create a cmake cache entry.

       When cmake is first run in an empty build tree, it creates a
       CMakeCache.txt file and populates it with customizable settings for
       the project.  This option may be used to specify a setting that takes
       priority over the project's default value.  The option may be repeated
       for as many cache entries as desired.

  -U <globbing_expr>
       Remove matching entries from CMake cache.

       This option may be used to remove one or more variables from the
       CMakeCache.txt file, globbing expressions using * and ? are supported.
       The option may be repeated for as many cache entries as desired.

       Use with care, you can make your CMakeCache.txt non-working.

  -G <generator-name>
       Specify a build system generator.

       CMake may support multiple native build systems on certain platforms.
       A generator is responsible for generating a particular build system.
       Possible generator names are specified in the Generators section.

  -T <toolset-name>
       Specify toolset name if supported by generator.

       Some CMake generators support a toolset name to be given to the native
       build system to choose a compiler.  This is supported only on specific
       generators:

         Visual Studio >= 10
         Xcode >= 3.0

       See native build system documentation for allowed toolset names.

  -Wno-dev
       Suppress developer warnings.

       Suppress warnings that are meant for the author of the CMakeLists.txt
       files.

  -Wdev
       Enable developer warnings.

       Enable warnings that are meant for the author of the CMakeLists.txt
       files.

  -E
       CMake command mode.

       For true platform independence, CMake provides a list of commands that
       can be used on all systems.  Run with -E help for the usage
       information.  Commands available are: chdir, compare_files, copy,
       copy_directory, copy_if_different, echo, echo_append, environment,
       make_directory, md5sum, remove, remove_directory, rename, tar, time,
       touch, touch_nocreate.  In addition, some platform specific commands
       are available.  On Windows: comspec, delete_regv, write_regv.  On
       UNIX: create_symlink.

  -i
       Run in wizard mode.

       Wizard mode runs cmake interactively without a GUI.  The user is
       prompted to answer questions about the project configuration.  The
       answers are used to set cmake cache values.

  -L[A][H]
       List non-advanced cached variables.

       List cache variables will run CMake and list all the variables from
       the CMake cache that are not marked as INTERNAL or ADVANCED.  This
       will effectively display current CMake settings, which can then be
       changed with -D option.  Changing some of the variables may result in
       more variables being created.  If A is specified, then it will display
       also advanced variables.  If H is specified, it will also display help
       for each variable.

  --build <dir>
       Build a CMake-generated project binary tree.

       This abstracts a native build tool's command-line interface with the
       following options:

         <dir>          = Project binary directory to be built.
         --target <tgt> = Build <tgt> instead of default targets.
         --config <cfg> = For multi-configuration tools, choose <cfg>.
         --clean-first  = Build target 'clean' first, then build.
                          (To clean only, use --target 'clean'.)
         --use-stderr   = Don't merge stdout/stderr output and pass the
                          original stdout/stderr handles to the native
                          tool so it can use the capabilities of the
                          calling terminal (e.g. colored output).
         --             = Pass remaining options to the native tool.

       Run cmake --build with no options for quick help.

  -N
       View mode only.

       Only load the cache.  Do not actually run configure and generate
       steps.

  -P <file>
       Process script mode.

       Process the given cmake file as a script written in the CMake
       language.  No configure or generate step is performed and the cache is
       not modified.  If variables are defined using -D, this must be done
       before the -P argument.

  --find-package
       Run in pkg-config like mode.

       Search a package using find_package() and print the resulting flags to
       stdout.  This can be used to use cmake instead of pkg-config to find
       installed libraries in plain Makefile-based projects or in
       autoconf-based projects (via share/aclocal/cmake.m4).

  --graphviz=[file]
       Generate graphviz of dependencies, see CMakeGraphVizOptions.cmake for
       more.

       Generate a graphviz input file that will contain all the library and
       executable dependencies in the project.  See the documentation for
       CMakeGraphVizOptions.cmake for more details.

  --system-information [file]
       Dump information about this system.

       Dump a wide range of information about the current system.  If run
       from the top of a binary tree for a CMake project it will dump
       additional information such as the cache, log files etc.

  --debug-trycompile
       Do not delete the try_compile build tree.  Only useful on one
       try_compile at a time.

       Do not delete the files and directories created for try_compile calls.
       This is useful in debugging failed try_compiles.  It may however
       change the results of the try-compiles as old junk from a previous
       try-compile may cause a different test to either pass or fail
       incorrectly.  This option is best used for one try-compile at a time,
       and only when debugging.

  --debug-output
       Put cmake in a debug mode.

       Print extra stuff during the cmake run like stack traces with
       message(send_error ) calls.

  --trace
       Put cmake in trace mode.

       Print a trace of all calls made and from where with message(send_error
       ) calls.

  --warn-uninitialized
       Warn about uninitialized values.

       Print a warning when an uninitialized variable is used.

  --warn-unused-vars
       Warn about unused variables.

       Find variables that are declared or set, but not used.

  --no-warn-unused-cli
       Don't warn about command line options.

       Don't find variables that are declared on the command line, but not
       used.

  --check-system-vars
       Find problems with variable usage in system files.

       Normally, unused and uninitialized variables are searched for only in
       CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR.  This flag tells CMake to warn
       about other files as well.

Commands

  add_compile_options
       Adds options to the compilation of source files.

         add_compile_options(<option> ...)

       Adds options to the compiler command line for sources in the current
       directory and below.  This command can be used to add any options, but
       alternative commands exist to add preprocessor definitions or include
       directories.  See documentation of the directory and target
       COMPILE_OPTIONS properties for details.  Arguments to
       add_compile_options may use "generator expressions" with the syntax
       "$<...>".  Generator expressions are evaluated during build system
       generation to produce information specific to each build
       configuration.  Valid expressions are:

         $<0:...>                  = empty string (ignores "...")
         $<1:...>                  = content of "..."
         $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
         $<CONFIGURATION>          = configuration name
         $<BOOL:...>               = '1' if the '...' is true, else '0'
         $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
         $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
         $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
         $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
         $<JOIN:list,...>          = joins the list with the content of "..."
         $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
         $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
         $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
         $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
         $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
         $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
         $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
         $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
         $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
         $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
         $<C_COMPILER_VERSION>     = The version of the C compiler used.
         $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
         $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
         $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
         $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
         $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
         $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

       where "tgt" is the name of a target.  Target file expressions produce
       a full path, but _DIR and _NAME versions can produce the directory and
       file name components:

         $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
         $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
         $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

       

         $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

       Note that tgt is not added as a dependency of the target this
       expression is evaluated on.

         $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
         $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

       Boolean expressions:

         $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
         $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
         $<NOT:?>                  = '0' if '?' is '1', else '1'

       where '?' is always either '0' or '1'.

       Expressions with an implicit 'this' target:

         $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.


  add_custom_command
       Add a custom build rule to the generated build system.

       There are two main signatures for add_custom_command The first
       signature is for adding a custom command to produce an output.

         add_custom_command(OUTPUT output1 [output2 ...]
                            COMMAND command1 [ARGS] [args1...]
                            [COMMAND command2 [ARGS] [args2...] ...]
                            [MAIN_DEPENDENCY depend]
                            [DEPENDS [depends...]]
                            [IMPLICIT_DEPENDS <lang1> depend1
                                             [<lang2> depend2] ...]
                            [WORKING_DIRECTORY dir]
                            [COMMENT comment] [VERBATIM] [APPEND])

       This defines a command to generate specified OUTPUT file(s).  A target
       created in the same directory (CMakeLists.txt file) that specifies any
       output of the custom command as a source file is given a rule to
       generate the file using the command at build time.  Do not list the
       output in more than one independent target that may build in parallel
       or the two instances of the rule may conflict (instead use
       add_custom_target to drive the command and make the other targets
       depend on that one).  If an output name is a relative path it will be
       interpreted relative to the build tree directory corresponding to the
       current source directory.  Note that MAIN_DEPENDENCY is completely
       optional and is used as a suggestion to visual studio about where to
       hang the custom command.  In makefile terms this creates a new target
       in the following form:

         OUTPUT: MAIN_DEPENDENCY DEPENDS
                 COMMAND

       If more than one command is specified they will be executed in order.
       The optional ARGS argument is for backward compatibility and will be
       ignored.

       The second signature adds a custom command to a target such as a
       library or executable.  This is useful for performing an operation
       before or after building the target.  The command becomes part of the
       target and will only execute when the target itself is built.  If the
       target is already built, the command will not execute.

         add_custom_command(TARGET target
                            PRE_BUILD | PRE_LINK | POST_BUILD
                            COMMAND command1 [ARGS] [args1...]
                            [COMMAND command2 [ARGS] [args2...] ...]
                            [WORKING_DIRECTORY dir]
                            [COMMENT comment] [VERBATIM])

       This defines a new command that will be associated with building the
       specified target.  When the command will happen is determined by which
       of the following is specified:

         PRE_BUILD - run before all other dependencies
         PRE_LINK - run after other dependencies
         POST_BUILD - run after the target has been built

       Note that the PRE_BUILD option is only supported on Visual Studio 7 or
       later.  For all other generators PRE_BUILD will be treated as
       PRE_LINK.

       If WORKING_DIRECTORY is specified the command will be executed in the
       directory given.  If it is a relative path it will be interpreted
       relative to the build tree directory corresponding to the current
       source directory.  If COMMENT is set, the value will be displayed as a
       message before the commands are executed at build time.  If APPEND is
       specified the COMMAND and DEPENDS option values are appended to the
       custom command for the first output specified.  There must have
       already been a previous call to this command with the same output.
       The COMMENT, WORKING_DIRECTORY, and MAIN_DEPENDENCY options are
       currently ignored when APPEND is given, but may be used in the future.

       If VERBATIM is given then all arguments to the commands will be
       escaped properly for the build tool so that the invoked command
       receives each argument unchanged.  Note that one level of escapes is
       still used by the CMake language processor before add_custom_command
       even sees the arguments.  Use of VERBATIM is recommended as it enables
       correct behavior.  When VERBATIM is not given the behavior is platform
       specific because there is no protection of tool-specific special
       characters.

       If the output of the custom command is not actually created as a file
       on disk it should be marked as SYMBOLIC with
       SET_SOURCE_FILES_PROPERTIES.

       The IMPLICIT_DEPENDS option requests scanning of implicit dependencies
       of an input file.  The language given specifies the programming
       language whose corresponding dependency scanner should be used.
       Currently only C and CXX language scanners are supported.  The
       language has to be specified for every file in the IMPLICIT_DEPENDS
       list.  Dependencies discovered from the scanning are added to those of
       the custom command at build time.  Note that the IMPLICIT_DEPENDS
       option is currently supported only for Makefile generators and will be
       ignored by other generators.

       If COMMAND specifies an executable target (created by ADD_EXECUTABLE)
       it will automatically be replaced by the location of the executable
       created at build time.  Additionally a target-level dependency will be
       added so that the executable target will be built before any target
       using this custom command.  However this does NOT add a file-level
       dependency that would cause the custom command to re-run whenever the
       executable is recompiled.

       Arguments to COMMAND may use "generator expressions" with the syntax
       "$<...>".  Generator expressions are evaluated during build system
       generation to produce information specific to each build
       configuration.  Valid expressions are:

         $<0:...>                  = empty string (ignores "...")
         $<1:...>                  = content of "..."
         $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
         $<CONFIGURATION>          = configuration name
         $<BOOL:...>               = '1' if the '...' is true, else '0'
         $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
         $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
         $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
         $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
         $<JOIN:list,...>          = joins the list with the content of "..."
         $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
         $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
         $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
         $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
         $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
         $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
         $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
         $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
         $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
         $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
         $<C_COMPILER_VERSION>     = The version of the C compiler used.
         $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
         $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
         $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
         $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
         $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
         $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

       where "tgt" is the name of a target.  Target file expressions produce
       a full path, but _DIR and _NAME versions can produce the directory and
       file name components:

         $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
         $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
         $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

       

         $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

       Note that tgt is not added as a dependency of the target this
       expression is evaluated on.

         $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
         $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

       Boolean expressions:

         $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
         $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
         $<NOT:?>                  = '0' if '?' is '1', else '1'

       where '?' is always either '0' or '1'.

       Expressions with an implicit 'this' target:

         $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.

       References to target names in generator expressions imply target-level
       dependencies, but NOT file-level dependencies.  List target names with
       the DEPENDS option to add file dependencies.

       The DEPENDS option specifies files on which the command depends.  If
       any dependency is an OUTPUT of another custom command in the same
       directory (CMakeLists.txt file) CMake automatically brings the other
       custom command into the target in which this command is built.  If
       DEPENDS is not specified the command will run whenever the OUTPUT is
       missing; if the command does not actually create the OUTPUT then the
       rule will always run.  If DEPENDS specifies any target (created by an
       ADD_* command) a target-level dependency is created to make sure the
       target is built before any target using this custom command.
       Additionally, if the target is an executable or library a file-level
       dependency is created to cause the custom command to re-run whenever
       the target is recompiled.


  add_custom_target
       Add a target with no output so it will always be built.

         add_custom_target(Name [ALL] [command1 [args1...]]
                           [COMMAND command2 [args2...] ...]
                           [DEPENDS depend depend depend ... ]
                           [WORKING_DIRECTORY dir]
                           [COMMENT comment] [VERBATIM]
                           [SOURCES src1 [src2...]])

       Adds a target with the given name that executes the given commands.
       The target has no output file and is ALWAYS CONSIDERED OUT OF DATE
       even if the commands try to create a file with the name of the target.
       Use ADD_CUSTOM_COMMAND to generate a file with dependencies.  By
       default nothing depends on the custom target.  Use ADD_DEPENDENCIES to
       add dependencies to or from other targets.  If the ALL option is
       specified it indicates that this target should be added to the default
       build target so that it will be run every time (the command cannot be
       called ALL).  The command and arguments are optional and if not
       specified an empty target will be created.  If WORKING_DIRECTORY is
       set, then the command will be run in that directory.  If it is a
       relative path it will be interpreted relative to the build tree
       directory corresponding to the current source directory.  If COMMENT
       is set, the value will be displayed as a message before the commands
       are executed at build time.  Dependencies listed with the DEPENDS
       argument may reference files and outputs of custom commands created
       with add_custom_command() in the same directory (CMakeLists.txt file).

       If VERBATIM is given then all arguments to the commands will be
       escaped properly for the build tool so that the invoked command
       receives each argument unchanged.  Note that one level of escapes is
       still used by the CMake language processor before add_custom_target
       even sees the arguments.  Use of VERBATIM is recommended as it enables
       correct behavior.  When VERBATIM is not given the behavior is platform
       specific because there is no protection of tool-specific special
       characters.

       The SOURCES option specifies additional source files to be included in
       the custom target.  Specified source files will be added to IDE
       project files for convenience in editing even if they have not build
       rules.

  add_definitions
       Adds -D define flags to the compilation of source files.

         add_definitions(-DFOO -DBAR ...)

       Adds flags to the compiler command line for sources in the current
       directory and below.  This command can be used to add any flags, but
       it was originally intended to add preprocessor definitions.  Flags
       beginning in -D or /D that look like preprocessor definitions are
       automatically added to the COMPILE_DEFINITIONS property for the
       current directory.  Definitions with non-trivial values may be left in
       the set of flags instead of being converted for reasons of backwards
       compatibility.  See documentation of the directory, target, and source
       file COMPILE_DEFINITIONS properties for details on adding preprocessor
       definitions to specific scopes and configurations.

  add_dependencies
       Add a dependency between top-level targets.

         add_dependencies(target-name depend-target1
                          depend-target2 ...)

       Make a top-level target depend on other top-level targets.  A
       top-level target is one created by ADD_EXECUTABLE, ADD_LIBRARY, or
       ADD_CUSTOM_TARGET.  Adding dependencies with this command can be used
       to make sure one target is built before another target.  Dependencies
       added to an IMPORTED target are followed transitively in its place
       since the target itself does not build.  See the DEPENDS option of
       ADD_CUSTOM_TARGET and ADD_CUSTOM_COMMAND for adding file-level
       dependencies in custom rules.  See the OBJECT_DEPENDS option in
       SET_SOURCE_FILES_PROPERTIES to add file-level dependencies to object
       files.

  add_executable
       Add an executable to the project using the specified source files.

         add_executable(<name> [WIN32] [MACOSX_BUNDLE]
                        [EXCLUDE_FROM_ALL]
                        source1 source2 ... sourceN)

       Adds an executable target called <name> to be built from the source
       files listed in the command invocation.  The <name> corresponds to the
       logical target name and must be globally unique within a project.  The
       actual file name of the executable built is constructed based on
       conventions of the native platform (such as <name>.exe or just
       <name>).

       By default the executable file will be created in the build tree
       directory corresponding to the source tree directory in which the
       command was invoked.  See documentation of the
       RUNTIME_OUTPUT_DIRECTORY target property to change this location.  See
       documentation of the OUTPUT_NAME target property to change the <name>
       part of the final file name.

       If WIN32 is given the property WIN32_EXECUTABLE will be set on the
       target created.  See documentation of that target property for
       details.

       If MACOSX_BUNDLE is given the corresponding property will be set on
       the created target.  See documentation of the MACOSX_BUNDLE target
       property for details.

       If EXCLUDE_FROM_ALL is given the corresponding property will be set on
       the created target.  See documentation of the EXCLUDE_FROM_ALL target
       property for details.

       The add_executable command can also create IMPORTED executable targets
       using this signature:

         add_executable(<name> IMPORTED [GLOBAL])

       An IMPORTED executable target references an executable file located
       outside the project.  No rules are generated to build it.  The target
       name has scope in the directory in which it is created and below, but
       the GLOBAL option extends visibility.  It may be referenced like any
       target built within the project.  IMPORTED executables are useful for
       convenient reference from commands like add_custom_command.  Details
       about the imported executable are specified by setting properties
       whose names begin in "IMPORTED_".  The most important such property is
       IMPORTED_LOCATION (and its per-configuration version
       IMPORTED_LOCATION_<CONFIG>) which specifies the location of the main
       executable file on disk.  See documentation of the IMPORTED_*
       properties for more information.

       The signature

         add_executable(<name> ALIAS <target>)

       creates an alias, such that <name> can be used to refer to <target> in
       subsequent commands.  The <name> does not appear in the generated
       buildsystem as a make target.  The <target> may not be an IMPORTED
       target or an ALIAS.  Alias targets can be used as linkable targets,
       targets to read properties from, executables for custom commands and
       custom targets.  They can also be tested for existance with the
       regular if(TARGET) subcommand.  The <name> may not be used to modify
       properties of <target>, that is, it may not be used as the operand of
       set_property, set_target_properties, target_link_libraries etc.  An
       ALIAS target may not be installed of exported.

  add_library
       Add a library to the project using the specified source files.

         add_library(<name> [STATIC | SHARED | MODULE]
                     [EXCLUDE_FROM_ALL]
                     source1 source2 ... sourceN)

       Adds a library target called <name> to be built from the source files
       listed in the command invocation.  The <name> corresponds to the
       logical target name and must be globally unique within a project.  The
       actual file name of the library built is constructed based on
       conventions of the native platform (such as lib<name>.a or
       <name>.lib).

       STATIC, SHARED, or MODULE may be given to specify the type of library
       to be created.  STATIC libraries are archives of object files for use
       when linking other targets.  SHARED libraries are linked dynamically
       and loaded at runtime.  MODULE libraries are plugins that are not
       linked into other targets but may be loaded dynamically at runtime
       using dlopen-like functionality.  If no type is given explicitly the
       type is STATIC or SHARED based on whether the current value of the
       variable BUILD_SHARED_LIBS is true.  For SHARED and MODULE libraries
       the POSITION_INDEPENDENT_CODE target property is set to TRUE
       automatically.

       By default the library file will be created in the build tree
       directory corresponding to the source tree directory in which the
       command was invoked.  See documentation of the
       ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and
       RUNTIME_OUTPUT_DIRECTORY target properties to change this location.
       See documentation of the OUTPUT_NAME target property to change the
       <name> part of the final file name.

       If EXCLUDE_FROM_ALL is given the corresponding property will be set on
       the created target.  See documentation of the EXCLUDE_FROM_ALL target
       property for details.

       The add_library command can also create IMPORTED library targets using
       this signature:

         add_library(<name> <SHARED|STATIC|MODULE|UNKNOWN> IMPORTED
                     [GLOBAL])

       An IMPORTED library target references a library file located outside
       the project.  No rules are generated to build it.  The target name has
       scope in the directory in which it is created and below, but the
       GLOBAL option extends visibility.  It may be referenced like any
       target built within the project.  IMPORTED libraries are useful for
       convenient reference from commands like target_link_libraries.
       Details about the imported library are specified by setting properties
       whose names begin in "IMPORTED_".  The most important such property is
       IMPORTED_LOCATION (and its per-configuration version
       IMPORTED_LOCATION_<CONFIG>) which specifies the location of the main
       library file on disk.  See documentation of the IMPORTED_* properties
       for more information.

       The signature

         add_library(<name> OBJECT <src>...)

       creates a special "object library" target.  An object library compiles
       source files but does not archive or link their object files into a
       library.  Instead other targets created by add_library or
       add_executable may reference the objects using an expression of the
       form $<TARGET_OBJECTS:objlib> as a source, where "objlib" is the
       object library name.  For example:

         add_library(... $<TARGET_OBJECTS:objlib> ...)
         add_executable(... $<TARGET_OBJECTS:objlib> ...)

       will include objlib's object files in a library and an executable
       along with those compiled from their own sources.  Object libraries
       may contain only sources (and headers) that compile to object files.
       They may contain custom commands generating such sources, but not
       PRE_BUILD, PRE_LINK, or POST_BUILD commands.  Object libraries cannot
       be imported, exported, installed, or linked.  Some native build
       systems may not like targets that have only object files, so consider
       adding at least one real source file to any target that references
       $<TARGET_OBJECTS:objlib>.

       The signature

         add_library(<name> ALIAS <target>)

       creates an alias, such that <name> can be used to refer to <target> in
       subsequent commands.  The <name> does not appear in the generated
       buildsystem as a make target.  The <target> may not be an IMPORTED
       target or an ALIAS.  Alias targets can be used as linkable targets,
       targets to read properties from.  They can also be tested for
       existance with the regular if(TARGET) subcommand.  The <name> may not
       be used to modify properties of <target>, that is, it may not be used
       as the operand of set_property, set_target_properties,
       target_link_libraries etc.  An ALIAS target may not be installed of
       exported.

  add_subdirectory
       Add a subdirectory to the build.

         add_subdirectory(source_dir [binary_dir] 
                          [EXCLUDE_FROM_ALL])

       Add a subdirectory to the build.  The source_dir specifies the
       directory in which the source CMakeLists.txt and code files are
       located.  If it is a relative path it will be evaluated with respect
       to the current directory (the typical usage), but it may also be an
       absolute path.  The binary_dir specifies the directory in which to
       place the output files.  If it is a relative path it will be evaluated
       with respect to the current output directory, but it may also be an
       absolute path.  If binary_dir is not specified, the value of
       source_dir, before expanding any relative path, will be used (the
       typical usage).  The CMakeLists.txt file in the specified source
       directory will be processed immediately by CMake before processing in
       the current input file continues beyond this command.

       If the EXCLUDE_FROM_ALL argument is provided then targets in the
       subdirectory will not be included in the ALL target of the parent
       directory by default, and will be excluded from IDE project files.
       Users must explicitly build targets in the subdirectory.  This is
       meant for use when the subdirectory contains a separate part of the
       project that is useful but not necessary, such as a set of examples.
       Typically the subdirectory should contain its own project() command
       invocation so that a full build system will be generated in the
       subdirectory (such as a VS IDE solution file).  Note that inter-target
       dependencies supercede this exclusion.  If a target built by the
       parent project depends on a target in the subdirectory, the dependee
       target will be included in the parent project build system to satisfy
       the dependency.

  add_test
       Add a test to the project with the specified arguments.

         add_test(testname Exename arg1 arg2 ... )

       If the ENABLE_TESTING command has been run, this command adds a test
       target to the current directory.  If ENABLE_TESTING has not been run,
       this command does nothing.  The tests are run by the testing subsystem
       by executing Exename with the specified arguments.  Exename can be
       either an executable built by this project or an arbitrary executable
       on the system (like tclsh).  The test will be run with the current
       working directory set to the CMakeList.txt files corresponding
       directory in the binary tree.

       

         add_test(NAME <name> [CONFIGURATIONS [Debug|Release|...]]
                  [WORKING_DIRECTORY dir]
                  COMMAND <command> [arg1 [arg2 ...]])

       Add a test called <name>.  The test name may not contain spaces,
       quotes, or other characters special in CMake syntax.  If COMMAND
       specifies an executable target (created by add_executable) it will
       automatically be replaced by the location of the executable created at
       build time.  If a CONFIGURATIONS option is given then the test will be
       executed only when testing under one of the named configurations.  If
       a WORKING_DIRECTORY option is given then the test will be executed in
       the given directory.

       Arguments after COMMAND may use "generator expressions" with the
       syntax "$<...>".  Generator expressions are evaluated during build
       system generation to produce information specific to each build
       configuration.  Valid expressions are:

         $<0:...>                  = empty string (ignores "...")
         $<1:...>                  = content of "..."
         $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
         $<CONFIGURATION>          = configuration name
         $<BOOL:...>               = '1' if the '...' is true, else '0'
         $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
         $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
         $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
         $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
         $<JOIN:list,...>          = joins the list with the content of "..."
         $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
         $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
         $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
         $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
         $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
         $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
         $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
         $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
         $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
         $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
         $<C_COMPILER_VERSION>     = The version of the C compiler used.
         $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
         $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
         $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
         $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
         $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
         $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

       where "tgt" is the name of a target.  Target file expressions produce
       a full path, but _DIR and _NAME versions can produce the directory and
       file name components:

         $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
         $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
         $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

       

         $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

       Note that tgt is not added as a dependency of the target this
       expression is evaluated on.

         $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
         $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

       Boolean expressions:

         $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
         $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
         $<NOT:?>                  = '0' if '?' is '1', else '1'

       where '?' is always either '0' or '1'.

       Example usage:

         add_test(NAME mytest
                  COMMAND testDriver --config $<CONFIGURATION>
                                     --exe $<TARGET_FILE:myexe>)

       This creates a test "mytest" whose command runs a testDriver tool
       passing the configuration name and the full path to the executable
       file produced by target "myexe".

  aux_source_directory
       Find all source files in a directory.

         aux_source_directory(<dir> <variable>)

       Collects the names of all the source files in the specified directory
       and stores the list in the <variable> provided.  This command is
       intended to be used by projects that use explicit template
       instantiation.  Template instantiation files can be stored in a
       "Templates" subdirectory and collected automatically using this
       command to avoid manually listing all instantiations.

       It is tempting to use this command to avoid writing the list of source
       files for a library or executable target.  While this seems to work,
       there is no way for CMake to generate a build system that knows when a
       new source file has been added.  Normally the generated build system
       knows when it needs to rerun CMake because the CMakeLists.txt file is
       modified to add a new source.  When the source is just added to the
       directory without modifying this file, one would have to manually
       rerun CMake to generate a build system incorporating the new file.

  build_command
       Get the command line to build this project.

         build_command(<variable>
                       [CONFIGURATION <config>]
                       [PROJECT_NAME <projname>]
                       [TARGET <target>])

       Sets the given <variable> to a string containing the command line for
       building one configuration of a target in a project using the build
       tool appropriate for the current CMAKE_GENERATOR.

       If CONFIGURATION is omitted, CMake chooses a reasonable default value
       for multi-configuration generators.  CONFIGURATION is ignored for
       single-configuration generators.

       If PROJECT_NAME is omitted, the resulting command line will build the
       top level PROJECT in the current build tree.

       If TARGET is omitted, the resulting command line will build
       everything, effectively using build target 'all' or 'ALL_BUILD'.

         build_command(<cachevariable> <makecommand>)

       This second signature is deprecated, but still available for backwards
       compatibility.  Use the first signature instead.

       Sets the given <cachevariable> to a string containing the command to
       build this project from the root of the build tree using the build
       tool given by <makecommand>.  <makecommand> should be the full path to
       msdev, devenv, nmake, make or one of the end user build tools.

  cmake_host_system_information
       Query host system specific information.

         cmake_host_system_information(RESULT <variable> QUERY <key> ...)

       Queries system information of the host system on which cmake runs.
       One or more <key> can be provided to select the information to be
       queried.  The list of queried values is stored in <variable>.

       <key> can be one of the following values:

         NUMBER_OF_LOGICAL_CORES   = Number of logical cores.
         NUMBER_OF_PHYSICAL_CORES  = Number of physical cores.
         HOSTNAME                  = Hostname.
         FQDN                      = Fully qualified domain name.
         TOTAL_VIRTUAL_MEMORY      = Total virtual memory in megabytes.
         AVAILABLE_VIRTUAL_MEMORY  = Available virtual memory in megabytes.
         TOTAL_PHYSICAL_MEMORY     = Total physical memory in megabytes.
         AVAILABLE_PHYSICAL_MEMORY = Available physical memory in megabytes.


  cmake_minimum_required
       Set the minimum required version of cmake for a project.

         cmake_minimum_required(VERSION major[.minor[.patch[.tweak]]]
                                [FATAL_ERROR])

       If the current version of CMake is lower than that required it will
       stop processing the project and report an error.  When a version
       higher than 2.4 is specified the command implicitly invokes

         cmake_policy(VERSION major[.minor[.patch[.tweak]]])

       which sets the cmake policy version level to the version specified.
       When version 2.4 or lower is given the command implicitly invokes

         cmake_policy(VERSION 2.4)

       which enables compatibility features for CMake 2.4 and lower.

       The FATAL_ERROR option is accepted but ignored by CMake 2.6 and
       higher.  It should be specified so CMake versions 2.4 and lower fail
       with an error instead of just a warning.

  cmake_policy
       Manage CMake Policy settings.

       As CMake evolves it is sometimes necessary to change existing behavior
       in order to fix bugs or improve implementations of existing features.
       The CMake Policy mechanism is designed to help keep existing projects
       building as new versions of CMake introduce changes in behavior.  Each
       new policy (behavioral change) is given an identifier of the form
       "CMP<NNNN>" where "<NNNN>" is an integer index.  Documentation
       associated with each policy describes the OLD and NEW behavior and the
       reason the policy was introduced.  Projects may set each policy to
       select the desired behavior.  When CMake needs to know which behavior
       to use it checks for a setting specified by the project.  If no
       setting is available the OLD behavior is assumed and a warning is
       produced requesting that the policy be set.

       The cmake_policy command is used to set policies to OLD or NEW
       behavior.  While setting policies individually is supported, we
       encourage projects to set policies based on CMake versions.

         cmake_policy(VERSION major.minor[.patch[.tweak]])

       Specify that the current CMake list file is written for the given
       version of CMake.  All policies introduced in the specified version or
       earlier will be set to use NEW behavior.  All policies introduced
       after the specified version will be unset (unless variable
       CMAKE_POLICY_DEFAULT_CMP<NNNN> sets a default).  This effectively
       requests behavior preferred as of a given CMake version and tells
       newer CMake versions to warn about their new policies.  The policy
       version specified must be at least 2.4 or the command will report an
       error.  In order to get compatibility features supporting versions
       earlier than 2.4 see documentation of policy CMP0001.

         cmake_policy(SET CMP<NNNN> NEW)
         cmake_policy(SET CMP<NNNN> OLD)

       Tell CMake to use the OLD or NEW behavior for a given policy.
       Projects depending on the old behavior of a given policy may silence a
       policy warning by setting the policy state to OLD.  Alternatively one
       may fix the project to work with the new behavior and set the policy
       state to NEW.

         cmake_policy(GET CMP<NNNN> <variable>)

       Check whether a given policy is set to OLD or NEW behavior.  The
       output variable value will be "OLD" or "NEW" if the policy is set, and
       empty otherwise.

       CMake keeps policy settings on a stack, so changes made by the
       cmake_policy command affect only the top of the stack.  A new entry on
       the policy stack is managed automatically for each subdirectory to
       protect its parents and siblings.  CMake also manages a new entry for
       scripts loaded by include() and find_package() commands except when
       invoked with the NO_POLICY_SCOPE option (see also policy CMP0011).
       The cmake_policy command provides an interface to manage custom
       entries on the policy stack:

         cmake_policy(PUSH)
         cmake_policy(POP)

       Each PUSH must have a matching POP to erase any changes.  This is
       useful to make temporary changes to policy settings.

       Functions and macros record policy settings when they are created and
       use the pre-record policies when they are invoked.  If the function or
       macro implementation sets policies, the changes automatically
       propagate up through callers until they reach the closest nested
       policy stack entry.

  configure_file
       Copy a file to another location and modify its contents.

         configure_file(<input> <output>
                        [COPYONLY] [ESCAPE_QUOTES] [@ONLY] 
                        [NEWLINE_STYLE [UNIX|DOS|WIN32|LF|CRLF] ])

       Copies a file <input> to file <output> and substitutes variable values
       referenced in the file content.  If <input> is a relative path it is
       evaluated with respect to the current source directory.  The <input>
       must be a file, not a directory.  If <output> is a relative path it is
       evaluated with respect to the current binary directory.  If <output>
       names an existing directory the input file is placed in that directory
       with its original name.

       If the <input> file is modified the build system will re-run CMake to
       re-configure the file and generate the build system again.

       This command replaces any variables in the input file referenced as
       ${VAR} or @VAR@ with their values as determined by CMake.  If a
       variable is not defined, it will be replaced with nothing.  If
       COPYONLY is specified, then no variable expansion will take place.  If
       ESCAPE_QUOTES is specified then any substituted quotes will be C-style
       escaped.  The file will be configured with the current values of CMake
       variables.  If @ONLY is specified, only variables of the form @VAR@
       will be replaced and ${VAR} will be ignored.  This is useful for
       configuring scripts that use ${VAR}.

       Input file lines of the form "#cmakedefine VAR ..." will be replaced
       with either "#define VAR ..." or "/* #undef VAR */" depending on
       whether VAR is set in CMake to any value not considered a false
       constant by the if() command.  (Content of "...", if any, is processed
       as above.) Input file lines of the form "#cmakedefine01 VAR" will be
       replaced with either "#define VAR 1" or "#define VAR 0" similarly.

       With NEWLINE_STYLE the line ending could be adjusted:

           'UNIX' or 'LF' for \n, 'DOS', 'WIN32' or 'CRLF' for \r\n.

       COPYONLY must not be used with NEWLINE_STYLE.


  create_test_sourcelist
       Create a test driver and source list for building test programs.

         create_test_sourcelist(sourceListName driverName
                                test1 test2 test3
                                EXTRA_INCLUDE include.h
                                FUNCTION function)

       A test driver is a program that links together many small tests into a
       single executable.  This is useful when building static executables
       with large libraries to shrink the total required size.  The list of
       source files needed to build the test driver will be in
       sourceListName.  DriverName is the name of the test driver program.
       The rest of the arguments consist of a list of test source files, can
       be semicolon separated.  Each test source file should have a function
       in it that is the same name as the file with no extension (foo.cxx
       should have int foo(int, char*[]);) DriverName will be able to call
       each of the tests by name on the command line.  If EXTRA_INCLUDE is
       specified, then the next argument is included into the generated file.
       If FUNCTION is specified, then the next argument is taken as a
       function name that is passed a pointer to ac and av.  This can be used
       to add extra command line processing to each test.  The cmake variable
       CMAKE_TESTDRIVER_BEFORE_TESTMAIN can be set to have code that will be
       placed directly before calling the test main function.
       CMAKE_TESTDRIVER_AFTER_TESTMAIN can be set to have code that will be
       placed directly after the call to the test main function.

  define_property
       Define and document custom properties.

         define_property(<GLOBAL | DIRECTORY | TARGET | SOURCE |
                          TEST | VARIABLE | CACHED_VARIABLE>
                          PROPERTY <name> [INHERITED]
                          BRIEF_DOCS <brief-doc> [docs...]
                          FULL_DOCS <full-doc> [docs...])

       Define one property in a scope for use with the set_property and
       get_property commands.  This is primarily useful to associate
       documentation with property names that may be retrieved with the
       get_property command.  The first argument determines the kind of scope
       in which the property should be used.  It must be one of the
       following:

         GLOBAL    = associated with the global namespace
         DIRECTORY = associated with one directory
         TARGET    = associated with one target
         SOURCE    = associated with one source file
         TEST      = associated with a test named with add_test
         VARIABLE  = documents a CMake language variable
         CACHED_VARIABLE = documents a CMake cache variable

       Note that unlike set_property and get_property no actual scope needs
       to be given; only the kind of scope is important.

       The required PROPERTY option is immediately followed by the name of
       the property being defined.

       If the INHERITED option then the get_property command will chain up to
       the next higher scope when the requested property is not set in the
       scope given to the command.  DIRECTORY scope chains to GLOBAL.
       TARGET, SOURCE, and TEST chain to DIRECTORY.

       The BRIEF_DOCS and FULL_DOCS options are followed by strings to be
       associated with the property as its brief and full documentation.
       Corresponding options to the get_property command will retrieve the
       documentation.

  else
       Starts the else portion of an if block.

         else(expression)

       See the if command.

  elseif
       Starts the elseif portion of an if block.

         elseif(expression)

       See the if command.

  enable_language
       Enable a language (CXX/C/Fortran/etc)

         enable_language(<lang> [OPTIONAL] )

       This command enables support for the named language in CMake.  This is
       the same as the project command but does not create any of the extra
       variables that are created by the project command.  Example languages
       are CXX, C, Fortran.

       This command must be called in file scope, not in a function call.
       Furthermore, it must be called in the highest directory common to all
       targets using the named language directly for compiling sources or
       indirectly through link dependencies.  It is simplest to enable all
       needed languages in the top-level directory of a project.

       The OPTIONAL keyword is a placeholder for future implementation and
       does not currently work.

  enable_testing
       Enable testing for current directory and below.

         enable_testing()

       Enables testing for this directory and below.  See also the add_test
       command.  Note that ctest expects to find a test file in the build
       directory root.  Therefore, this command should be in the source
       directory root.

  execute_process
       Execute one or more child processes.

         execute_process(COMMAND <cmd1> [args1...]]
                         [COMMAND <cmd2> [args2...] [...]]
                         [WORKING_DIRECTORY <directory>]
                         [TIMEOUT <seconds>]
                         [RESULT_VARIABLE <variable>]
                         [OUTPUT_VARIABLE <variable>]
                         [ERROR_VARIABLE <variable>]
                         [INPUT_FILE <file>]
                         [OUTPUT_FILE <file>]
                         [ERROR_FILE <file>]
                         [OUTPUT_QUIET]
                         [ERROR_QUIET]
                         [OUTPUT_STRIP_TRAILING_WHITESPACE]
                         [ERROR_STRIP_TRAILING_WHITESPACE])

       Runs the given sequence of one or more commands with the standard
       output of each process piped to the standard input of the next.  A
       single standard error pipe is used for all processes.  If
       WORKING_DIRECTORY is given the named directory will be set as the
       current working directory of the child processes.  If TIMEOUT is given
       the child processes will be terminated if they do not finish in the
       specified number of seconds (fractions are allowed).  If
       RESULT_VARIABLE is given the variable will be set to contain the
       result of running the processes.  This will be an integer return code
       from the last child or a string describing an error condition.  If
       OUTPUT_VARIABLE or ERROR_VARIABLE are given the variable named will be
       set with the contents of the standard output and standard error pipes
       respectively.  If the same variable is named for both pipes their
       output will be merged in the order produced.  If INPUT_FILE,
       OUTPUT_FILE, or ERROR_FILE is given the file named will be attached to
       the standard input of the first process, standard output of the last
       process, or standard error of all processes respectively.  If
       OUTPUT_QUIET or ERROR_QUIET is given then the standard output or
       standard error results will be quietly ignored.  If more than one
       OUTPUT_* or ERROR_* option is given for the same pipe the precedence
       is not specified.  If no OUTPUT_* or ERROR_* options are given the
       output will be shared with the corresponding pipes of the CMake
       process itself.

       The execute_process command is a newer more powerful version of
       exec_program, but the old command has been kept for compatibility.

  export
       Export targets from the build tree for use by outside projects.

         export(TARGETS [target1 [target2 [...]]] [NAMESPACE <namespace>]
                [APPEND] FILE <filename> [EXPORT_LINK_INTERFACE_LIBRARIES])

       Create a file <filename> that may be included by outside projects to
       import targets from the current project's build tree.  This is useful
       during cross-compiling to build utility executables that can run on
       the host platform in one project and then import them into another
       project being compiled for the target platform.  If the NAMESPACE
       option is given the <namespace> string will be prepended to all target
       names written to the file.  If the APPEND option is given the
       generated code will be appended to the file instead of overwriting it.
       The EXPORT_LINK_INTERFACE_LIBRARIES keyword, if present, causes the
       contents of the properties matching
       (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)? to be exported, when
       policy CMP0022 is NEW.  If a library target is included in the export
       but a target to which it links is not included the behavior is
       unspecified.

       The file created by this command is specific to the build tree and
       should never be installed.  See the install(EXPORT) command to export
       targets from an installation tree.

       Do not set properties that affect the location of a target after
       passing it to this command.  These include properties whose names
       match "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
       "(IMPLIB_)?(PREFIX|SUFFIX)", or "LINKER_LANGUAGE".  Failure to follow
       this rule is not diagnosed and leaves the location of the target
       undefined.

         export(PACKAGE <name>)

       Store the current build directory in the CMake user package registry
       for package <name>.  The find_package command may consider the
       directory while searching for package <name>.  This helps dependent
       projects find and use a package from the current project's build tree
       without help from the user.  Note that the entry in the package
       registry that this command creates works only in conjunction with a
       package configuration file (<name>Config.cmake) that works with the
       build tree.

  file
       File manipulation command.

         file(WRITE filename "message to write"... )
         file(APPEND filename "message to write"... )
         file(READ filename variable [LIMIT numBytes] [OFFSET offset] [HEX])
         file(<MD5|SHA1|SHA224|SHA256|SHA384|SHA512> filename variable)
         file(STRINGS filename variable [LIMIT_COUNT num]
              [LIMIT_INPUT numBytes] [LIMIT_OUTPUT numBytes]
              [LENGTH_MINIMUM numBytes] [LENGTH_MAXIMUM numBytes]
              [NEWLINE_CONSUME] [REGEX regex]
              [NO_HEX_CONVERSION])
         file(GLOB variable [RELATIVE path] [globbing expressions]...)
         file(GLOB_RECURSE variable [RELATIVE path] 
              [FOLLOW_SYMLINKS] [globbing expressions]...)
         file(RENAME <oldname> <newname>)
         file(REMOVE [file1 ...])
         file(REMOVE_RECURSE [file1 ...])
         file(MAKE_DIRECTORY [directory1 directory2 ...])
         file(RELATIVE_PATH variable directory file)
         file(TO_CMAKE_PATH path result)
         file(TO_NATIVE_PATH path result)
         file(DOWNLOAD url file [INACTIVITY_TIMEOUT timeout]
              [TIMEOUT timeout] [STATUS status] [LOG log] [SHOW_PROGRESS]
              [EXPECTED_HASH ALGO=value] [EXPECTED_MD5 sum]
              [TLS_VERIFY on|off] [TLS_CAINFO file])
         file(UPLOAD filename url [INACTIVITY_TIMEOUT timeout]
              [TIMEOUT timeout] [STATUS status] [LOG log] [SHOW_PROGRESS])
         file(TIMESTAMP filename variable [<format string>] [UTC])
         file(GENERATE OUTPUT output_file
              <INPUT input_file|CONTENT input_content>
              [CONDITION expression])

       WRITE will write a message into a file called 'filename'.  It
       overwrites the file if it already exists, and creates the file if it
       does not exist.  (If the file is a build input, use configure_file to
       update the file only when its content changes.)

       APPEND will write a message into a file same as WRITE, except it will
       append it to the end of the file

       READ will read the content of a file and store it into the variable.
       It will start at the given offset and read up to numBytes.  If the
       argument HEX is given, the binary data will be converted to
       hexadecimal representation and this will be stored in the variable.

       MD5, SHA1, SHA224, SHA256, SHA384, and SHA512 will compute a
       cryptographic hash of the content of a file.

       STRINGS will parse a list of ASCII strings from a file and store it in
       a variable.  Binary data in the file are ignored.  Carriage return
       (CR) characters are ignored.  It works also for Intel Hex and Motorola
       S-record files, which are automatically converted to binary format
       when reading them.  Disable this using NO_HEX_CONVERSION.

       LIMIT_COUNT sets the maximum number of strings to return.  LIMIT_INPUT
       sets the maximum number of bytes to read from the input file.
       LIMIT_OUTPUT sets the maximum number of bytes to store in the output
       variable.  LENGTH_MINIMUM sets the minimum length of a string to
       return.  Shorter strings are ignored.  LENGTH_MAXIMUM sets the maximum
       length of a string to return.  Longer strings are split into strings
       no longer than the maximum length.  NEWLINE_CONSUME allows newlines to
       be included in strings instead of terminating them.

       REGEX specifies a regular expression that a string must match to be
       returned.  Typical usage

         file(STRINGS myfile.txt myfile)

       stores a list in the variable "myfile" in which each item is a line
       from the input file.

       GLOB will generate a list of all files that match the globbing
       expressions and store it into the variable.  Globbing expressions are
       similar to regular expressions, but much simpler.  If RELATIVE flag is
       specified for an expression, the results will be returned as a
       relative path to the given path.  (We do not recommend using GLOB to
       collect a list of source files from your source tree.  If no
       CMakeLists.txt file changes when a source is added or removed then the
       generated build system cannot know when to ask CMake to regenerate.)

       Examples of globbing expressions include:

          *.cxx      - match all files with extension cxx
          *.vt?      - match all files with extension vta,...,vtz
          f[3-5].txt - match files f3.txt, f4.txt, f5.txt

       GLOB_RECURSE will generate a list similar to the regular GLOB, except
       it will traverse all the subdirectories of the matched directory and
       match the files.  Subdirectories that are symlinks are only traversed
       if FOLLOW_SYMLINKS is given or cmake policy CMP0009 is not set to NEW.
       See cmake --help-policy CMP0009 for more information.

       Examples of recursive globbing include:

          /dir/*.py  - match all python files in /dir and subdirectories

       MAKE_DIRECTORY will create the given directories, also if their parent
       directories don't exist yet

       RENAME moves a file or directory within a filesystem, replacing the
       destination atomically.

       REMOVE will remove the given files, also in subdirectories

       REMOVE_RECURSE will remove the given files and directories, also
       non-empty directories

       RELATIVE_PATH will determine relative path from directory to the given
       file.

       TO_CMAKE_PATH will convert path into a cmake style path with unix /.
       The input can be a single path or a system path like "$ENV{PATH}".
       Note the double quotes around the ENV call TO_CMAKE_PATH only takes
       one argument.  This command will also convert the native list
       delimiters for a list of paths like the PATH environment variable.

       TO_NATIVE_PATH works just like TO_CMAKE_PATH, but will convert from a
       cmake style path into the native path style \ for windows and / for
       UNIX.

       DOWNLOAD will download the given URL to the given file.  If LOG var is
       specified a log of the download will be put in var.  If STATUS var is
       specified the status of the operation will be put in var.  The status
       is returned in a list of length 2.  The first element is the numeric
       return value for the operation, and the second element is a string
       value for the error.  A 0 numeric error means no error in the
       operation.  If TIMEOUT time is specified, the operation will timeout
       after time seconds, time should be specified as an integer.  The
       INACTIVITY_TIMEOUT specifies an integer number of seconds of
       inactivity after which the operation should terminate.  If
       EXPECTED_HASH ALGO=value is specified, the operation will verify that
       the downloaded file's actual hash matches the expected value, where
       ALGO is one of MD5, SHA1, SHA224, SHA256, SHA384, or SHA512.  If it
       does not match, the operation fails with an error.  ("EXPECTED_MD5
       sum" is short-hand for "EXPECTED_HASH MD5=sum".) If SHOW_PROGRESS is
       specified, progress information will be printed as status messages
       until the operation is complete.  For https URLs CMake must be built
       with OpenSSL.  TLS/SSL certificates are not checked by default.  Set
       TLS_VERIFY to ON to check certificates and/or use EXPECTED_HASH to
       verify downloaded content.  Set TLS_CAINFO to specify a custom
       Certificate Authority file.  If either TLS option is not given CMake
       will check variables CMAKE_TLS_VERIFY and CMAKE_TLS_CAINFO,
       respectively.

       UPLOAD will upload the given file to the given URL.  If LOG var is
       specified a log of the upload will be put in var.  If STATUS var is
       specified the status of the operation will be put in var.  The status
       is returned in a list of length 2.  The first element is the numeric
       return value for the operation, and the second element is a string
       value for the error.  A 0 numeric error means no error in the
       operation.  If TIMEOUT time is specified, the operation will timeout
       after time seconds, time should be specified as an integer.  The
       INACTIVITY_TIMEOUT specifies an integer number of seconds of
       inactivity after which the operation should terminate.  If
       SHOW_PROGRESS is specified, progress information will be printed as
       status messages until the operation is complete.

       TIMESTAMP will write a string representation of the modification time
       of filename to variable.

       Should the command be unable to obtain a timestamp variable will be
       set to the empty string "".

       See documentation of the string TIMESTAMP sub-command for more
       details.

       The file() command also provides COPY and INSTALL signatures:

         file(<COPY|INSTALL> files... DESTINATION <dir>
              [FILE_PERMISSIONS permissions...]
              [DIRECTORY_PERMISSIONS permissions...]
              [NO_SOURCE_PERMISSIONS] [USE_SOURCE_PERMISSIONS]
              [FILES_MATCHING]
              [[PATTERN <pattern> | REGEX <regex>]
               [EXCLUDE] [PERMISSIONS permissions...]] [...])

       The COPY signature copies files, directories, and symlinks to a
       destination folder.  Relative input paths are evaluated with respect
       to the current source directory, and a relative destination is
       evaluated with respect to the current build directory.  Copying
       preserves input file timestamps, and optimizes out a file if it exists
       at the destination with the same timestamp.  Copying preserves input
       permissions unless explicit permissions or NO_SOURCE_PERMISSIONS are
       given (default is USE_SOURCE_PERMISSIONS).  See the install(DIRECTORY)
       command for documentation of permissions, PATTERN, REGEX, and EXCLUDE
       options.

       The INSTALL signature differs slightly from COPY: it prints status
       messages, and NO_SOURCE_PERMISSIONS is default.  Installation scripts
       generated by the install() command use this signature (with some
       undocumented options for internal use).

       GENERATE will write an <output_file> with content from an
       <input_file>, or from <input_content>.  The output is generated
       conditionally based on the content of the <condition>.  The file is
       written at CMake generate-time and the input may contain generator
       expressions.  The <condition>, <output_file> and <input_file> may also
       contain generator expressions.  The <condition> must evaluate to
       either '0' or '1'.  The <output_file> must evaluate to a unique name
       among all configurations and among all invocations of file(GENERATE).

  find_file
       Find the full path to a file.

          find_file(<VAR> name1 [path1 path2 ...])

       This is the short-hand signature for the command that is sufficient in
       many cases.  It is the same as find_file(<VAR> name1 [PATHS path1
       path2 ...])

          find_file(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                     ONLY_CMAKE_FIND_ROOT_PATH |
                     NO_CMAKE_FIND_ROOT_PATH]
                   )

       This command is used to find a full path to named file.  A cache entry
       named by <VAR> is created to store the result of this command.  If the
       full path to a file is found the result is stored in the variable and
       the search will not be repeated unless the variable is cleared.  If
       nothing is found, the result will be <VAR>-NOTFOUND, and the search
       will be attempted again the next time find_file is invoked with the
       same variable.  The name of the full path to a file that is searched
       for is specified by the names listed after the NAMES argument.
       Additional search locations can be specified after the PATHS argument.
       If ENV var is found in the HINTS or PATHS section the environment
       variable var will be read and converted from a system environment
       variable to a cmake style list of paths.  For example ENV PATH would
       be a way to list the system path variable.  The argument after DOC
       will be used for the documentation string in the cache.  PATH_SUFFIXES
       specifies additional subdirectories to check below each search path.

       If NO_DEFAULT_PATH is specified, then no additional paths are added to
       the search.  If NO_DEFAULT_PATH is not specified, the search process
       is as follows:

       1.  Search paths specified in cmake-specific cache variables.  These
       are intended to be used on the command line with a -DVAR=value.  This
       can be skipped if NO_CMAKE_PATH is passed.

          <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH

       2.  Search paths specified in cmake-specific environment variables.
       These are intended to be set in the user's shell configuration.  This
       can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.

          <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH

       3.  Search the paths specified by the HINTS option.  These should be
       paths computed by system introspection, such as a hint provided by the
       location of another item already found.  Hard-coded guesses should be
       specified with the PATHS option.

       4.  Search the standard system environment variables.  This can be
       skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

          PATH
          INCLUDE

       5.  Search cmake variables defined in the Platform files for the
       current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
       passed.

          <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_INCLUDE_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH

       6.  Search the paths specified by the PATHS option or in the
       short-hand version of the command.  These are typically hard-coded
       guesses.

       On Darwin or systems supporting OS X Frameworks, the cmake variable
       CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:

          "FIRST"  - Try to find frameworks before standard
                     libraries or headers. This is the default on Darwin.
          "LAST"   - Try to find frameworks after standard
                     libraries or headers.
          "ONLY"   - Only try to find frameworks.
          "NEVER" - Never try to find frameworks.

       On Darwin or systems supporting OS X Application Bundles, the cmake
       variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
       following:

          "FIRST"  - Try to find application bundles before standard
                     programs. This is the default on Darwin.
          "LAST"   - Try to find application bundles after standard
                     programs.
          "ONLY"   - Only try to find application bundles.
          "NEVER" - Never try to find application bundles.

       The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
       directories to be prepended to all other search directories.  This
       effectively "re-roots" the entire search under given locations.  By
       default it is empty.  It is especially useful when cross-compiling to
       point to the root directory of the target environment and CMake will
       search there too.  By default at first the directories listed in
       CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
       searched.  The default behavior can be adjusted by setting
       CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.  This behavior can be manually
       overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
       the search order will be as described above.  If
       NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
       used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
       directories will be searched.

       The default search order is designed to be most-specific to
       least-specific for common use cases.  Projects may override the order
       by simply calling the command multiple times and using the NO_*
       options:

          find_file(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_file(<VAR> NAMES name)

       Once one of the calls succeeds the result variable will be set and
       stored in the cache so that no call will search again.

  find_library
       Find a library.

          find_library(<VAR> name1 [path1 path2 ...])

       This is the short-hand signature for the command that is sufficient in
       many cases.  It is the same as find_library(<VAR> name1 [PATHS path1
       path2 ...])

          find_library(
                    <VAR>
                    name | NAMES name1 [name2 ...] [NAMES_PER_DIR]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                     ONLY_CMAKE_FIND_ROOT_PATH |
                     NO_CMAKE_FIND_ROOT_PATH]
                   )

       This command is used to find a library.  A cache entry named by <VAR>
       is created to store the result of this command.  If the library is
       found the result is stored in the variable and the search will not be
       repeated unless the variable is cleared.  If nothing is found, the
       result will be <VAR>-NOTFOUND, and the search will be attempted again
       the next time find_library is invoked with the same variable.  The
       name of the library that is searched for is specified by the names
       listed after the NAMES argument.  Additional search locations can be
       specified after the PATHS argument.  If ENV var is found in the HINTS
       or PATHS section the environment variable var will be read and
       converted from a system environment variable to a cmake style list of
       paths.  For example ENV PATH would be a way to list the system path
       variable.  The argument after DOC will be used for the documentation
       string in the cache.  PATH_SUFFIXES specifies additional
       subdirectories to check below each search path.

       If NO_DEFAULT_PATH is specified, then no additional paths are added to
       the search.  If NO_DEFAULT_PATH is not specified, the search process
       is as follows:

       1.  Search paths specified in cmake-specific cache variables.  These
       are intended to be used on the command line with a -DVAR=value.  This
       can be skipped if NO_CMAKE_PATH is passed.

          <prefix>/lib/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/lib for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_LIBRARY_PATH
          CMAKE_FRAMEWORK_PATH

       2.  Search paths specified in cmake-specific environment variables.
       These are intended to be set in the user's shell configuration.  This
       can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.

          <prefix>/lib/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/lib for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_LIBRARY_PATH
          CMAKE_FRAMEWORK_PATH

       3.  Search the paths specified by the HINTS option.  These should be
       paths computed by system introspection, such as a hint provided by the
       location of another item already found.  Hard-coded guesses should be
       specified with the PATHS option.

       4.  Search the standard system environment variables.  This can be
       skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

          PATH
          LIB

       5.  Search cmake variables defined in the Platform files for the
       current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
       passed.

          <prefix>/lib/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/lib for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_LIBRARY_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH

       6.  Search the paths specified by the PATHS option or in the
       short-hand version of the command.  These are typically hard-coded
       guesses.

       On Darwin or systems supporting OS X Frameworks, the cmake variable
       CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:

          "FIRST"  - Try to find frameworks before standard
                     libraries or headers. This is the default on Darwin.
          "LAST"   - Try to find frameworks after standard
                     libraries or headers.
          "ONLY"   - Only try to find frameworks.
          "NEVER" - Never try to find frameworks.

       On Darwin or systems supporting OS X Application Bundles, the cmake
       variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
       following:

          "FIRST"  - Try to find application bundles before standard
                     programs. This is the default on Darwin.
          "LAST"   - Try to find application bundles after standard
                     programs.
          "ONLY"   - Only try to find application bundles.
          "NEVER" - Never try to find application bundles.

       The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
       directories to be prepended to all other search directories.  This
       effectively "re-roots" the entire search under given locations.  By
       default it is empty.  It is especially useful when cross-compiling to
       point to the root directory of the target environment and CMake will
       search there too.  By default at first the directories listed in
       CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
       searched.  The default behavior can be adjusted by setting
       CMAKE_FIND_ROOT_PATH_MODE_LIBRARY.  This behavior can be manually
       overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
       the search order will be as described above.  If
       NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
       used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
       directories will be searched.

       The default search order is designed to be most-specific to
       least-specific for common use cases.  Projects may override the order
       by simply calling the command multiple times and using the NO_*
       options:

          find_library(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_library(<VAR> NAMES name)

       Once one of the calls succeeds the result variable will be set and
       stored in the cache so that no call will search again.

       When more than one value is given to the NAMES option this command by
       default will consider one name at a time and search every directory
       for it.  The NAMES_PER_DIR option tells this command to consider one
       directory at a time and search for all names in it.

       If the library found is a framework, then VAR will be set to the full
       path to the framework <fullPath>/A.framework.  When a full path to a
       framework is used as a library, CMake will use a -framework A, and a
       -F<fullPath> to link the framework to the target.

       If the global property FIND_LIBRARY_USE_LIB64_PATHS is set all search
       paths will be tested as normal, with "64/" appended, and with all
       matches of "lib/" replaced with "lib64/".  This property is
       automatically set for the platforms that are known to need it if at
       least one of the languages supported by the PROJECT command is
       enabled.

  find_package
       Load settings for an external project.

         find_package(<package> [version] [EXACT] [QUIET] [MODULE]
                      [REQUIRED] [[COMPONENTS] [components...]]
                      [OPTIONAL_COMPONENTS components...]
                      [NO_POLICY_SCOPE])

       Finds and loads settings from an external project.  <package>_FOUND
       will be set to indicate whether the package was found.  When the
       package is found package-specific information is provided through
       variables and imported targets documented by the package itself.  The
       QUIET option disables messages if the package cannot be found.  The
       MODULE option disables the second signature documented below.  The
       REQUIRED option stops processing with an error message if the package
       cannot be found.

       A package-specific list of required components may be listed after the
       COMPONENTS option (or after the REQUIRED option if present).
       Additional optional components may be listed after
       OPTIONAL_COMPONENTS.  Available components and their influence on
       whether a package is considered to be found are defined by the target
       package.

       The [version] argument requests a version with which the package found
       should be compatible (format is major[.minor[.patch[.tweak]]]).  The
       EXACT option requests that the version be matched exactly.  If no
       [version] and/or component list is given to a recursive invocation
       inside a find-module, the corresponding arguments are forwarded
       automatically from the outer call (including the EXACT flag for
       [version]).  Version support is currently provided only on a
       package-by-package basis (details below).

       User code should generally look for packages using the above simple
       signature.  The remainder of this command documentation specifies the
       full command signature and details of the search process.  Project
       maintainers wishing to provide a package to be found by this command
       are encouraged to read on.

       The command has two modes by which it searches for packages: "Module"
       mode and "Config" mode.  Module mode is available when the command is
       invoked with the above reduced signature.  CMake searches for a file
       called "Find<package>.cmake" in the CMAKE_MODULE_PATH followed by the
       CMake installation.  If the file is found, it is read and processed by
       CMake.  It is responsible for finding the package, checking the
       version, and producing any needed messages.  Many find-modules provide
       limited or no support for versioning; check the module documentation.
       If no module is found and the MODULE option is not given the command
       proceeds to Config mode.

       The complete Config mode command signature is:

         find_package(<package> [version] [EXACT] [QUIET]
                      [REQUIRED] [[COMPONENTS] [components...]]
                      [CONFIG|NO_MODULE]
                      [NO_POLICY_SCOPE]
                      [NAMES name1 [name2 ...]]
                      [CONFIGS config1 [config2 ...]]
                      [HINTS path1 [path2 ... ]]
                      [PATHS path1 [path2 ... ]]
                      [PATH_SUFFIXES suffix1 [suffix2 ...]]
                      [NO_DEFAULT_PATH]
                      [NO_CMAKE_ENVIRONMENT_PATH]
                      [NO_CMAKE_PATH]
                      [NO_SYSTEM_ENVIRONMENT_PATH]
                      [NO_CMAKE_PACKAGE_REGISTRY]
                      [NO_CMAKE_BUILDS_PATH]
                      [NO_CMAKE_SYSTEM_PATH]
                      [NO_CMAKE_SYSTEM_PACKAGE_REGISTRY]
                      [CMAKE_FIND_ROOT_PATH_BOTH |
                       ONLY_CMAKE_FIND_ROOT_PATH |
                       NO_CMAKE_FIND_ROOT_PATH])

       The CONFIG option may be used to skip Module mode explicitly and
       switch to Config mode.  It is synonymous to using NO_MODULE.  Config
       mode is also implied by use of options not specified in the reduced
       signature.

       Config mode attempts to locate a configuration file provided by the
       package to be found.  A cache entry called <package>_DIR is created to
       hold the directory containing the file.  By default the command
       searches for a package with the name <package>.  If the NAMES option
       is given the names following it are used instead of <package>.  The
       command searches for a file called "<name>Config.cmake" or
       "<lower-case-name>-config.cmake" for each name specified.  A
       replacement set of possible configuration file names may be given
       using the CONFIGS option.  The search procedure is specified below.
       Once found, the configuration file is read and processed by CMake.
       Since the file is provided by the package it already knows the
       location of package contents.  The full path to the configuration file
       is stored in the cmake variable <package>_CONFIG.

       All configuration files which have been considered by CMake while
       searching for an installation of the package with an appropriate
       version are stored in the cmake variable <package>_CONSIDERED_CONFIGS,
       the associated versions in <package>_CONSIDERED_VERSIONS.

       If the package configuration file cannot be found CMake will generate
       an error describing the problem unless the QUIET argument is
       specified.  If REQUIRED is specified and the package is not found a
       fatal error is generated and the configure step stops executing.  If
       <package>_DIR has been set to a directory not containing a
       configuration file CMake will ignore it and search from scratch.

       When the [version] argument is given Config mode will only find a
       version of the package that claims compatibility with the requested
       version (format is major[.minor[.patch[.tweak]]]).  If the EXACT
       option is given only a version of the package claiming an exact match
       of the requested version may be found.  CMake does not establish any
       convention for the meaning of version numbers.  Package version
       numbers are checked by "version" files provided by the packages
       themselves.  For a candidate package configuration file
       "<config-file>.cmake" the corresponding version file is located next
       to it and named either "<config-file>-version.cmake" or
       "<config-file>Version.cmake".  If no such version file is available
       then the configuration file is assumed to not be compatible with any
       requested version.  A basic version file containing generic version
       matching code can be created using the macro
       write_basic_package_version_file(), see its documentation for more
       details.  When a version file is found it is loaded to check the
       requested version number.  The version file is loaded in a nested
       scope in which the following variables have been defined:

         PACKAGE_FIND_NAME          = the <package> name
         PACKAGE_FIND_VERSION       = full requested version string
         PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0
         PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0
         PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0
         PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0
         PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4

       The version file checks whether it satisfies the requested version and
       sets these variables:

         PACKAGE_VERSION            = full provided version string
         PACKAGE_VERSION_EXACT      = true if version is exact match
         PACKAGE_VERSION_COMPATIBLE = true if version is compatible
         PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version

       These variables are checked by the find_package command to determine
       whether the configuration file provides an acceptable version.  They
       are not available after the find_package call returns.  If the version
       is acceptable the following variables are set:

         <package>_VERSION       = full provided version string
         <package>_VERSION_MAJOR = major version if provided, else 0
         <package>_VERSION_MINOR = minor version if provided, else 0
         <package>_VERSION_PATCH = patch version if provided, else 0
         <package>_VERSION_TWEAK = tweak version if provided, else 0
         <package>_VERSION_COUNT = number of version components, 0 to 4

       and the corresponding package configuration file is loaded.  When
       multiple package configuration files are available whose version files
       claim compatibility with the version requested it is unspecified which
       one is chosen.  No attempt is made to choose a highest or closest
       version number.

       Config mode provides an elaborate interface and search procedure.
       Much of the interface is provided for completeness and for use
       internally by find-modules loaded by Module mode.  Most user code
       should simply call

         find_package(<package> [major[.minor]] [EXACT] [REQUIRED|QUIET])

       in order to find a package.  Package maintainers providing CMake
       package configuration files are encouraged to name and install them
       such that the procedure outlined below will find them without
       requiring use of additional options.

       CMake constructs a set of possible installation prefixes for the
       package.  Under each prefix several directories are searched for a
       configuration file.  The tables below show the directories searched.
       Each entry is meant for installation trees following Windows (W), UNIX
       (U), or Apple (A) conventions.

         <prefix>/                                               (W)
         <prefix>/(cmake|CMake)/                                 (W)
         <prefix>/<name>*/                                       (W)
         <prefix>/<name>*/(cmake|CMake)/                         (W)
         <prefix>/(lib/<arch>|lib|share)/cmake/<name>*/          (U)
         <prefix>/(lib/<arch>|lib|share)/<name>*/                (U)
         <prefix>/(lib/<arch>|lib|share)/<name>*/(cmake|CMake)/  (U)

       On systems supporting OS X Frameworks and Application Bundles the
       following directories are searched for frameworks or bundles
       containing a configuration file:

         <prefix>/<name>.framework/Resources/                    (A)
         <prefix>/<name>.framework/Resources/CMake/              (A)
         <prefix>/<name>.framework/Versions/*/Resources/         (A)
         <prefix>/<name>.framework/Versions/*/Resources/CMake/   (A)
         <prefix>/<name>.app/Contents/Resources/                 (A)
         <prefix>/<name>.app/Contents/Resources/CMake/           (A)

       In all cases the <name> is treated as case-insensitive and corresponds
       to any of the names specified (<package> or names given by NAMES).
       Paths with lib/<arch> are enabled if CMAKE_LIBRARY_ARCHITECTURE is
       set.  If PATH_SUFFIXES is specified the suffixes are appended to each
       (W) or (U) directory entry one-by-one.

       This set of directories is intended to work in cooperation with
       projects that provide configuration files in their installation trees.
       Directories above marked with (W) are intended for installations on
       Windows where the prefix may point at the top of an application's
       installation directory.  Those marked with (U) are intended for
       installations on UNIX platforms where the prefix is shared by multiple
       packages.  This is merely a convention, so all (W) and (U) directories
       are still searched on all platforms.  Directories marked with (A) are
       intended for installations on Apple platforms.  The cmake variables
       CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE determine the order of
       preference as specified below.

       The set of installation prefixes is constructed using the following
       steps.  If NO_DEFAULT_PATH is specified all NO_* options are enabled.

       1.  Search paths specified in cmake-specific cache variables.  These
       are intended to be used on the command line with a -DVAR=value.  This
       can be skipped if NO_CMAKE_PATH is passed.

          CMAKE_PREFIX_PATH
          CMAKE_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH

       2.  Search paths specified in cmake-specific environment variables.
       These are intended to be set in the user's shell configuration.  This
       can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.

          <package>_DIR
          CMAKE_PREFIX_PATH
          CMAKE_FRAMEWORK_PATH
          CMAKE_APPBUNDLE_PATH

       3.  Search paths specified by the HINTS option.  These should be paths
       computed by system introspection, such as a hint provided by the
       location of another item already found.  Hard-coded guesses should be
       specified with the PATHS option.

       4.  Search the standard system environment variables.  This can be
       skipped if NO_SYSTEM_ENVIRONMENT_PATH is passed.  Path entries ending
       in "/bin" or "/sbin" are automatically converted to their parent
       directories.

          PATH

       5.  Search project build trees recently configured in a CMake GUI.
       This can be skipped if NO_CMAKE_BUILDS_PATH is passed.  It is intended
       for the case when a user is building multiple dependent projects one
       after another.

       6.  Search paths stored in the CMake user package registry.  This can
       be skipped if NO_CMAKE_PACKAGE_REGISTRY is passed.  On Windows a
       <package> may appear under registry key

         HKEY_CURRENT_USER\Software\Kitware\CMake\Packages\<package>

       as a REG_SZ value, with arbitrary name, that specifies the directory
       containing the package configuration file.  On UNIX platforms a
       <package> may appear under the directory

         ~/.cmake/packages/<package>

       as a file, with arbitrary name, whose content specifies the directory
       containing the package configuration file.  See the export(PACKAGE)
       command to create user package registry entries for project build
       trees.

       7.  Search cmake variables defined in the Platform files for the
       current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
       passed.

          CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH
          CMAKE_SYSTEM_APPBUNDLE_PATH

       8.  Search paths stored in the CMake system package registry.  This
       can be skipped if NO_CMAKE_SYSTEM_PACKAGE_REGISTRY is passed.  On
       Windows a <package> may appear under registry key

         HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<package>

       as a REG_SZ value, with arbitrary name, that specifies the directory
       containing the package configuration file.  There is no system package
       registry on non-Windows platforms.

       9.  Search paths specified by the PATHS option.  These are typically
       hard-coded guesses.

       On Darwin or systems supporting OS X Frameworks, the cmake variable
       CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:

          "FIRST"  - Try to find frameworks before standard
                     libraries or headers. This is the default on Darwin.
          "LAST"   - Try to find frameworks after standard
                     libraries or headers.
          "ONLY"   - Only try to find frameworks.
          "NEVER" - Never try to find frameworks.

       On Darwin or systems supporting OS X Application Bundles, the cmake
       variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
       following:

          "FIRST"  - Try to find application bundles before standard
                     programs. This is the default on Darwin.
          "LAST"   - Try to find application bundles after standard
                     programs.
          "ONLY"   - Only try to find application bundles.
          "NEVER" - Never try to find application bundles.

       The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
       directories to be prepended to all other search directories.  This
       effectively "re-roots" the entire search under given locations.  By
       default it is empty.  It is especially useful when cross-compiling to
       point to the root directory of the target environment and CMake will
       search there too.  By default at first the directories listed in
       CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
       searched.  The default behavior can be adjusted by setting
       CMAKE_FIND_ROOT_PATH_MODE_PACKAGE.  This behavior can be manually
       overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
       the search order will be as described above.  If
       NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
       used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
       directories will be searched.

       The default search order is designed to be most-specific to
       least-specific for common use cases.  Projects may override the order
       by simply calling the command multiple times and using the NO_*
       options:

          find_package(<package> PATHS paths... NO_DEFAULT_PATH)
          find_package(<package>)

       Once one of the calls succeeds the result variable will be set and
       stored in the cache so that no call will search again.

       Every non-REQUIRED find_package() call can be disabled by setting the
       variable CMAKE_DISABLE_FIND_PACKAGE_<package> to TRUE.  See the
       documentation for the CMAKE_DISABLE_FIND_PACKAGE_<package> variable
       for more information.

       When loading a find module or package configuration file find_package
       defines variables to provide information about the call arguments (and
       restores their original state before returning):

        <package>_FIND_REQUIRED      = true if REQUIRED option was given
        <package>_FIND_QUIETLY       = true if QUIET option was given
        <package>_FIND_VERSION       = full requested version string
        <package>_FIND_VERSION_MAJOR = major version if requested, else 0
        <package>_FIND_VERSION_MINOR = minor version if requested, else 0
        <package>_FIND_VERSION_PATCH = patch version if requested, else 0
        <package>_FIND_VERSION_TWEAK = tweak version if requested, else 0
        <package>_FIND_VERSION_COUNT = number of version components, 0 to 4
        <package>_FIND_VERSION_EXACT = true if EXACT option was given
        <package>_FIND_COMPONENTS    = list of requested components
        <package>_FIND_REQUIRED_<c>  = true if component <c> is required
                                       false if component <c> is optional

       In Module mode the loaded find module is responsible to honor the
       request detailed by these variables; see the find module for details.
       In Config mode find_package handles REQUIRED, QUIET, and version
       options automatically but leaves it to the package configuration file
       to handle components in a way that makes sense for the package.  The
       package configuration file may set <package>_FOUND to false to tell
       find_package that component requirements are not satisfied.

       See the cmake_policy() command documentation for discussion of the
       NO_POLICY_SCOPE option.

  find_path
       Find the directory containing a file.

          find_path(<VAR> name1 [path1 path2 ...])

       This is the short-hand signature for the command that is sufficient in
       many cases.  It is the same as find_path(<VAR> name1 [PATHS path1
       path2 ...])

          find_path(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                     ONLY_CMAKE_FIND_ROOT_PATH |
                     NO_CMAKE_FIND_ROOT_PATH]
                   )

       This command is used to find a directory containing the named file.  A
       cache entry named by <VAR> is created to store the result of this
       command.  If the file in a directory is found the result is stored in
       the variable and the search will not be repeated unless the variable
       is cleared.  If nothing is found, the result will be <VAR>-NOTFOUND,
       and the search will be attempted again the next time find_path is
       invoked with the same variable.  The name of the file in a directory
       that is searched for is specified by the names listed after the NAMES
       argument.  Additional search locations can be specified after the
       PATHS argument.  If ENV var is found in the HINTS or PATHS section the
       environment variable var will be read and converted from a system
       environment variable to a cmake style list of paths.  For example ENV
       PATH would be a way to list the system path variable.  The argument
       after DOC will be used for the documentation string in the cache.
       PATH_SUFFIXES specifies additional subdirectories to check below each
       search path.

       If NO_DEFAULT_PATH is specified, then no additional paths are added to
       the search.  If NO_DEFAULT_PATH is not specified, the search process
       is as follows:

       1.  Search paths specified in cmake-specific cache variables.  These
       are intended to be used on the command line with a -DVAR=value.  This
       can be skipped if NO_CMAKE_PATH is passed.

          <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH

       2.  Search paths specified in cmake-specific environment variables.
       These are intended to be set in the user's shell configuration.  This
       can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.

          <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/include for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_INCLUDE_PATH
          CMAKE_FRAMEWORK_PATH

       3.  Search the paths specified by the HINTS option.  These should be
       paths computed by system introspection, such as a hint provided by the
       location of another item already found.  Hard-coded guesses should be
       specified with the PATHS option.

       4.  Search the standard system environment variables.  This can be
       skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

          PATH
          INCLUDE

       5.  Search cmake variables defined in the Platform files for the
       current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
       passed.

          <prefix>/include/<arch> if CMAKE_LIBRARY_ARCHITECTURE is set, and
          <prefix>/include for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_INCLUDE_PATH
          CMAKE_SYSTEM_FRAMEWORK_PATH

       6.  Search the paths specified by the PATHS option or in the
       short-hand version of the command.  These are typically hard-coded
       guesses.

       On Darwin or systems supporting OS X Frameworks, the cmake variable
       CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:

          "FIRST"  - Try to find frameworks before standard
                     libraries or headers. This is the default on Darwin.
          "LAST"   - Try to find frameworks after standard
                     libraries or headers.
          "ONLY"   - Only try to find frameworks.
          "NEVER" - Never try to find frameworks.

       On Darwin or systems supporting OS X Application Bundles, the cmake
       variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
       following:

          "FIRST"  - Try to find application bundles before standard
                     programs. This is the default on Darwin.
          "LAST"   - Try to find application bundles after standard
                     programs.
          "ONLY"   - Only try to find application bundles.
          "NEVER" - Never try to find application bundles.

       The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
       directories to be prepended to all other search directories.  This
       effectively "re-roots" the entire search under given locations.  By
       default it is empty.  It is especially useful when cross-compiling to
       point to the root directory of the target environment and CMake will
       search there too.  By default at first the directories listed in
       CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
       searched.  The default behavior can be adjusted by setting
       CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.  This behavior can be manually
       overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
       the search order will be as described above.  If
       NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
       used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
       directories will be searched.

       The default search order is designed to be most-specific to
       least-specific for common use cases.  Projects may override the order
       by simply calling the command multiple times and using the NO_*
       options:

          find_path(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_path(<VAR> NAMES name)

       Once one of the calls succeeds the result variable will be set and
       stored in the cache so that no call will search again.

       When searching for frameworks, if the file is specified as A/b.h, then
       the framework search will look for A.framework/Headers/b.h.  If that
       is found the path will be set to the path to the framework.  CMake
       will convert this to the correct -F option to include the file.

  find_program
       Find an executable program.

          find_program(<VAR> name1 [path1 path2 ...])

       This is the short-hand signature for the command that is sufficient in
       many cases.  It is the same as find_program(<VAR> name1 [PATHS path1
       path2 ...])

          find_program(
                    <VAR>
                    name | NAMES name1 [name2 ...]
                    [HINTS path1 [path2 ... ENV var]]
                    [PATHS path1 [path2 ... ENV var]]
                    [PATH_SUFFIXES suffix1 [suffix2 ...]]
                    [DOC "cache documentation string"]
                    [NO_DEFAULT_PATH]
                    [NO_CMAKE_ENVIRONMENT_PATH]
                    [NO_CMAKE_PATH]
                    [NO_SYSTEM_ENVIRONMENT_PATH]
                    [NO_CMAKE_SYSTEM_PATH]
                    [CMAKE_FIND_ROOT_PATH_BOTH |
                     ONLY_CMAKE_FIND_ROOT_PATH |
                     NO_CMAKE_FIND_ROOT_PATH]
                   )

       This command is used to find a program.  A cache entry named by <VAR>
       is created to store the result of this command.  If the program is
       found the result is stored in the variable and the search will not be
       repeated unless the variable is cleared.  If nothing is found, the
       result will be <VAR>-NOTFOUND, and the search will be attempted again
       the next time find_program is invoked with the same variable.  The
       name of the program that is searched for is specified by the names
       listed after the NAMES argument.  Additional search locations can be
       specified after the PATHS argument.  If ENV var is found in the HINTS
       or PATHS section the environment variable var will be read and
       converted from a system environment variable to a cmake style list of
       paths.  For example ENV PATH would be a way to list the system path
       variable.  The argument after DOC will be used for the documentation
       string in the cache.  PATH_SUFFIXES specifies additional
       subdirectories to check below each search path.

       If NO_DEFAULT_PATH is specified, then no additional paths are added to
       the search.  If NO_DEFAULT_PATH is not specified, the search process
       is as follows:

       1.  Search paths specified in cmake-specific cache variables.  These
       are intended to be used on the command line with a -DVAR=value.  This
       can be skipped if NO_CMAKE_PATH is passed.

          <prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_PROGRAM_PATH
          CMAKE_APPBUNDLE_PATH

       2.  Search paths specified in cmake-specific environment variables.
       These are intended to be set in the user's shell configuration.  This
       can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.

          <prefix>/[s]bin for each <prefix> in CMAKE_PREFIX_PATH
          CMAKE_PROGRAM_PATH
          CMAKE_APPBUNDLE_PATH

       3.  Search the paths specified by the HINTS option.  These should be
       paths computed by system introspection, such as a hint provided by the
       location of another item already found.  Hard-coded guesses should be
       specified with the PATHS option.

       4.  Search the standard system environment variables.  This can be
       skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.

          PATH
          

       5.  Search cmake variables defined in the Platform files for the
       current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
       passed.

          <prefix>/[s]bin for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
          CMAKE_SYSTEM_PROGRAM_PATH
          CMAKE_SYSTEM_APPBUNDLE_PATH

       6.  Search the paths specified by the PATHS option or in the
       short-hand version of the command.  These are typically hard-coded
       guesses.

          "LAST"   - Try to find frameworks after standard
                     libraries or headers.
          "ONLY"   - Only try to find frameworks.
          "NEVER" - Never try to find frameworks.

       On Darwin or systems supporting OS X Application Bundles, the cmake
       variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
       following:

          "FIRST"  - Try to find application bundles before standard
                     programs. This is the default on Darwin.
          "LAST"   - Try to find application bundles after standard
                     programs.
          "ONLY"   - Only try to find application bundles.
          "NEVER" - Never try to find application bundles.

       The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
       directories to be prepended to all other search directories.  This
       effectively "re-roots" the entire search under given locations.  By
       default it is empty.  It is especially useful when cross-compiling to
       point to the root directory of the target environment and CMake will
       search there too.  By default at first the directories listed in
       CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be

          find_program(<VAR> NAMES name PATHS paths... NO_DEFAULT_PATH)
          find_program(<VAR> NAMES name)

       Once one of the calls succeeds the result variable will be set and
       stored in the cache so that no call will search again.

  fltk_wrap_ui
       Create FLTK user interfaces Wrappers.

         fltk_wrap_ui(resultingLibraryName source1
                      source2 ... sourceN )

       Produce .h and .cxx files for all the .fl and .fld files listed.  The
       resulting .h and .cxx files will be added to a variable named
       resultingLibraryName_FLTK_UI_SRCS which should be added to your
       library.

  foreach
       Evaluate a group of commands for each value in a list.

         foreach(loop_var arg1 arg2 ...)
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         endforeach(loop_var)

       All commands between foreach and the matching endforeach are recorded
       without being invoked.  Once the endforeach is evaluated, the recorded
       list of commands is invoked once for each argument listed in the
       original foreach command.  Before each iteration of the loop
       "${loop_var}" will be set as a variable with the current value in the
       list.

         foreach(loop_var RANGE total)
         foreach(loop_var RANGE start stop [step])

       Foreach can also iterate over a generated range of numbers.  There are
       three types of this iteration:

       * When specifying single number, the range will have elements 0 to
       "total".

       * When specifying two numbers, the range will have elements from the
       first number to the second number.

       * The third optional number is the increment used to iterate from the
       first number to the second number.

         foreach(loop_var IN [LISTS [list1 [...]]]
                             [ITEMS [item1 [...]]])

       Iterates over a precise list of items.  The LISTS option names
       list-valued variables to be traversed, including empty elements (an
       empty string is a zero-length list).  The ITEMS option ends argument
       parsing and includes all arguments following it in the iteration.

  function
       Start recording a function for later invocation as a command.

         function(<name> [arg1 [arg2 [arg3 ...]]])
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         endfunction(<name>)

       Define a function named <name> that takes arguments named arg1 arg2
       arg3 (...).  Commands listed after function, but before the matching
       endfunction, are not invoked until the function is invoked.  When it
       is invoked, the commands recorded in the function are first modified
       by replacing formal parameters (${arg1}) with the arguments passed,
       and then invoked as normal commands.  In addition to referencing the
       formal parameters you can reference the variable ARGC which will be
       set to the number of arguments passed into the function as well as
       ARGV0 ARGV1 ARGV2 ...  which will have the actual values of the
       arguments passed in.  This facilitates creating functions with
       optional arguments.  Additionally ARGV holds the list of all arguments
       given to the function and ARGN holds the list of arguments past the
       last expected argument.

       A function opens a new scope: see set(var PARENT_SCOPE) for details.

       See the cmake_policy() command documentation for the behavior of
       policies inside functions.

  get_cmake_property
       Get a property of the CMake instance.

         get_cmake_property(VAR property)

       Get a property from the CMake instance.  The value of the property is
       stored in the variable VAR.  If the property is not found, VAR will be
       set to "NOTFOUND".  Some supported properties include: VARIABLES,
       CACHE_VARIABLES, COMMANDS, MACROS, and COMPONENTS.

       See also the more general get_property() command.

  get_directory_property
       Get a property of DIRECTORY scope.

         get_directory_property(<variable> [DIRECTORY <dir>] <prop-name>)

       Store a property of directory scope in the named variable.  If the
       property is not defined the empty-string is returned.  The DIRECTORY
       argument specifies another directory from which to retrieve the
       property value.  The specified directory must have already been
       traversed by CMake.

         get_directory_property(<variable> [DIRECTORY <dir>]
                                DEFINITION <var-name>)

       Get a variable definition from a directory.  This form is useful to
       get a variable definition from another directory.

       See also the more general get_property() command.

  get_filename_component
       Get a specific component of a full filename.

         get_filename_component(<VAR> <FileName> <COMP> [CACHE])

       Set <VAR> to a component of <FileName>, where <COMP> is one of:

        DIRECTORY = Directory without file name
        NAME      = File name without directory
        EXT       = File name longest extension (.b.c from d/a.b.c)
        NAME_WE   = File name without directory or longest extension
        ABSOLUTE  = Full path to file
        REALPATH  = Full path to existing file with symlinks resolved
        PATH      = Legacy alias for DIRECTORY (use for CMake <= 2.8.11)

       Paths are returned with forward slashes and have no trailing slahes.
       The longest file extension is always considered.  If the optional
       CACHE argument is specified, the result variable is added to the
       cache.

         get_filename_component(<VAR> FileName
                                PROGRAM [PROGRAM_ARGS <ARG_VAR>]
                                [CACHE])

       The program in FileName will be found in the system search path or
       left as a full path.  If PROGRAM_ARGS is present with PROGRAM, then
       any command-line arguments present in the FileName string are split
       from the program name and stored in <ARG_VAR>.  This is used to
       separate a program name from its arguments in a command line string.

  get_property
       Get a property.

         get_property(<variable>
                      <GLOBAL             |
                       DIRECTORY [dir]    |
                       TARGET    <target> |
                       SOURCE    <source> |
                       TEST      <test>   |
                       CACHE     <entry>  |
                       VARIABLE>
                      PROPERTY <name>
                      [SET | DEFINED | BRIEF_DOCS | FULL_DOCS])

       Get one property from one object in a scope.  The first argument
       specifies the variable in which to store the result.  The second
       argument determines the scope from which to get the property.  It must
       be one of the following:

       GLOBAL scope is unique and does not accept a name.

       DIRECTORY scope defaults to the current directory but another
       directory (already processed by CMake) may be named by full or
       relative path.

       TARGET scope must name one existing target.

       SOURCE scope must name one source file.

       TEST scope must name one existing test.

       CACHE scope must name one cache entry.

       VARIABLE scope is unique and does not accept a name.

       The required PROPERTY option is immediately followed by the name of
       the property to get.  If the property is not set an empty value is
       returned.  If the SET option is given the variable is set to a boolean
       value indicating whether the property has been set.  If the DEFINED
       option is given the variable is set to a boolean value indicating
       whether the property has been defined such as with define_property.
       If BRIEF_DOCS or FULL_DOCS is given then the variable is set to a
       string containing documentation for the requested property.  If
       documentation is requested for a property that has not been defined
       NOTFOUND is returned.

  get_source_file_property
       Get a property for a source file.

         get_source_file_property(VAR file property)

       Get a property from a source file.  The value of the property is
       stored in the variable VAR.  If the property is not found, VAR will be
       set to "NOTFOUND".  Use set_source_files_properties to set property
       values.  Source file properties usually control how the file is built.
       One property that is always there is LOCATION

       See also the more general get_property() command.

  get_target_property
       Get a property from a target.

         get_target_property(VAR target property)

       Get a property from a target.  The value of the property is stored in
       the variable VAR.  If the property is not found, VAR will be set to
       "NOTFOUND".  Use set_target_properties to set property values.
       Properties are usually used to control how a target is built, but some
       query the target instead.  This command can get properties for any
       target so far created.  The targets do not need to be in the current
       CMakeLists.txt file.

       See also the more general get_property() command.

  get_test_property
       Get a property of the test.

         get_test_property(test property VAR)

       Get a property from the Test.  The value of the property is stored in
       the variable VAR.  If the property is not found, VAR will be set to
       "NOTFOUND".  For a list of standard properties you can type cmake
       --help-property-list

       See also the more general get_property() command.

  if
       Conditionally execute a group of commands.

         if(expression)
           # then section.
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         elseif(expression2)
           # elseif section.
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         else(expression)
           # else section.
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         endif(expression)

       Evaluates the given expression.  If the result is true, the commands
       in the THEN section are invoked.  Otherwise, the commands in the else
       section are invoked.  The elseif and else sections are optional.  You
       may have multiple elseif clauses.  Note that the expression in the
       else and endif clause is optional.  Long expressions can be used and
       there is a traditional order of precedence.  Parenthetical expressions
       are evaluated first followed by unary operators such as EXISTS,
       COMMAND, and DEFINED.  Then any EQUAL, LESS, GREATER, STRLESS,
       STRGREATER, STREQUAL, MATCHES will be evaluated.  Then NOT operators
       and finally AND, OR operators will be evaluated.  Possible expressions
       are:

         if(<constant>)

       True if the constant is 1, ON, YES, TRUE, Y, or a non-zero number.
       False if the constant is 0, OFF, NO, FALSE, N, IGNORE, NOTFOUND, '',
       or ends in the suffix '-NOTFOUND'.  Named boolean constants are
       case-insensitive.  If the argument is not one of these constants, it
       is treated as a variable:

         if(<variable>)

       True if the variable is defined to a value that is not a false
       constant.  False otherwise.  (Note macro arguments are not variables.)

         if(NOT <expression>)

       True if the expression is not true.

         if(<expr1> AND <expr2>)

       True if both expressions would be considered true individually.

         if(<expr1> OR <expr2>)

       True if either expression would be considered true individually.

         if(COMMAND command-name)

       True if the given name is a command, macro or function that can be
       invoked.

         if(POLICY policy-id)

       True if the given name is an existing policy (of the form CMP<NNNN>).

         if(TARGET target-name)

       True if the given name is an existing target, built or imported.

         if(EXISTS file-name)
         if(EXISTS directory-name)

       True if the named file or directory exists.  Behavior is well-defined
       only for full paths.

         if(file1 IS_NEWER_THAN file2)

       True if file1 is newer than file2 or if one of the two files doesn't
       exist.  Behavior is well-defined only for full paths.  If the file
       time stamps are exactly the same, an IS_NEWER_THAN comparison returns
       true, so that any dependent build operations will occur in the event
       of a tie.  This includes the case of passing the same file name for
       both file1 and file2.

         if(IS_DIRECTORY directory-name)

       True if the given name is a directory.  Behavior is well-defined only
       for full paths.

         if(IS_SYMLINK file-name)

       True if the given name is a symbolic link.  Behavior is well-defined
       only for full paths.

         if(IS_ABSOLUTE path)

       True if the given path is an absolute path.

         if(<variable|string> MATCHES regex)

       True if the given string or variable's value matches the given regular
       expression.

         if(<variable|string> LESS <variable|string>)
         if(<variable|string> GREATER <variable|string>)
         if(<variable|string> EQUAL <variable|string>)

       True if the given string or variable's value is a valid number and the
       inequality or equality is true.

         if(<variable|string> STRLESS <variable|string>)
         if(<variable|string> STRGREATER <variable|string>)
         if(<variable|string> STREQUAL <variable|string>)

       True if the given string or variable's value is lexicographically less
       (or greater, or equal) than the string or variable on the right.

         if(<variable|string> VERSION_LESS <variable|string>)
         if(<variable|string> VERSION_EQUAL <variable|string>)
         if(<variable|string> VERSION_GREATER <variable|string>)

       Component-wise integer version number comparison (version format is
       major[.minor[.patch[.tweak]]]).

         if(DEFINED <variable>)

       True if the given variable is defined.  It does not matter if the
       variable is true or false just if it has been set.

         if((expression) AND (expression OR (expression)))

       The expressions inside the parenthesis are evaluated first and then
       the remaining expression is evaluated as in the previous examples.
       Where there are nested parenthesis the innermost are evaluated as part
       of evaluating the expression that contains them.

       The if command was written very early in CMake's history, predating
       the ${} variable evaluation syntax, and for convenience evaluates
       variables named by its arguments as shown in the above signatures.
       Note that normal variable evaluation with ${} applies before the if
       command even receives the arguments.  Therefore code like

         set(var1 OFF)
         set(var2 "var1")
         if(${var2})

       appears to the if command as

         if(var1)

       and is evaluated according to the if(<variable>) case documented
       above.  The result is OFF which is false.  However, if we remove the
       ${} from the example then the command sees

         if(var2)

       which is true because var2 is defined to "var1" which is not a false
       constant.

       Automatic evaluation applies in the other cases whenever the
       above-documented signature accepts <variable|string>:

       1) The left hand argument to MATCHES is first checked to see if it is
       a defined variable, if so the variable's value is used, otherwise the
       original value is used.

       2) If the left hand argument to MATCHES is missing it returns false
       without error

       3) Both left and right hand arguments to LESS GREATER EQUAL are
       independently tested to see if they are defined variables, if so their
       defined values are used otherwise the original value is used.

       4) Both left and right hand arguments to STRLESS STREQUAL STRGREATER
       are independently tested to see if they are defined variables, if so
       their defined values are used otherwise the original value is used.

       5) Both left and right hand argumemnts to VERSION_LESS VERSION_EQUAL
       VERSION_GREATER are independently tested to see if they are defined
       variables, if so their defined values are used otherwise the original
       value is used.

       6) The right hand argument to NOT is tested to see if it is a boolean
       constant, if so the value is used, otherwise it is assumed to be a
       variable and it is dereferenced.

       7) The left and right hand arguments to AND OR are independently
       tested to see if they are boolean constants, if so they are used as
       such, otherwise they are assumed to be variables and are dereferenced.



  include
       Load and run CMake code from a file or module.

         include(<file|module> [OPTIONAL] [RESULT_VARIABLE <VAR>]
                               [NO_POLICY_SCOPE])

       Load and run CMake code from the file given.  Variable reads and
       writes access the scope of the caller (dynamic scoping).  If OPTIONAL
       is present, then no error is raised if the file does not exist.  If
       RESULT_VARIABLE is given the variable will be set to the full filename
       which has been included or NOTFOUND if it failed.

       If a module is specified instead of a file, the file with name
       <modulename>.cmake is searched first in CMAKE_MODULE_PATH, then in the
       CMake module directory.  There is one exception to this: if the file
       which calls include() is located itself in the CMake module directory,
       then first the CMake module directory is searched and
       CMAKE_MODULE_PATH afterwards.  See also policy CMP0017.

       See the cmake_policy() command documentation for discussion of the
       NO_POLICY_SCOPE option.

  include_directories
       Add include directories to the build.

         include_directories([AFTER|BEFORE] [SYSTEM] dir1 dir2 ...)

       Add the given directories to those the compiler uses to search for
       include files.  Relative paths are interpreted as relative to the
       current source directory.

       The include directories are added to the directory property
       INCLUDE_DIRECTORIES for the current CMakeLists file.  They are also
       added to the target property INCLUDE_DIRECTORIES for each target in
       the current CMakeLists file.  The target property values are the ones
       used by the generators.

       By default the directories are appended onto the current list of
       directories.  This default behavior can be changed by setting
       CMAKE_INCLUDE_DIRECTORIES_BEFORE to ON.  By using AFTER or BEFORE
       explicitly, you can select between appending and prepending,
       independent of the default.

       If the SYSTEM option is given, the compiler will be told the
       directories are meant as system include directories on some platforms
       (signalling this setting might achieve effects such as the compiler
       skipping warnings, or these fixed-install system files not being
       considered in dependency calculations - see compiler docs).

  include_external_msproject
       Include an external Microsoft project file in a workspace.

         include_external_msproject(projectname location
                                    [TYPE projectTypeGUID]
                                    [GUID projectGUID]
                                    [PLATFORM platformName]
                                    dep1 dep2 ...)

       Includes an external Microsoft project in the generated workspace
       file.  Currently does nothing on UNIX.  This will create a target
       named [projectname].  This can be used in the add_dependencies command
       to make things depend on the external project.

       TYPE, GUID and PLATFORM are optional parameters that allow one to
       specify the type of project, id (GUID) of the project and the name of
       the target platform.  This is useful for projects requiring values
       other than the default (e.g.  WIX projects).  These options are not
       supported by the Visual Studio 6 generator.

  include_regular_expression
       Set the regular expression used for dependency checking.

         include_regular_expression(regex_match [regex_complain])

       Set the regular expressions used in dependency checking.  Only files
       matching regex_match will be traced as dependencies.  Only files
       matching regex_complain will generate warnings if they cannot be found
       (standard header paths are not searched).  The defaults are:

         regex_match    = "^.*$" (match everything)
         regex_complain = "^$" (match empty string only)

  install
       Specify rules to run at install time.

       This command generates installation rules for a project.  Rules
       specified by calls to this command within a source directory are
       executed in order during installation.  The order across directories
       is not defined.

       There are multiple signatures for this command.  Some of them define
       installation properties for files and targets.  Properties common to
       multiple signatures are covered here but they are valid only for
       signatures that specify them.

       DESTINATION arguments specify the directory on disk to which a file
       will be installed.  If a full path (with a leading slash or drive
       letter) is given it is used directly.  If a relative path is given it
       is interpreted relative to the value of CMAKE_INSTALL_PREFIX.  The
       prefix can be relocated at install time using DESTDIR mechanism
       explained in the CMAKE_INSTALL_PREFIX variable documentation.

       PERMISSIONS arguments specify permissions for installed files.  Valid
       permissions are OWNER_READ, OWNER_WRITE, OWNER_EXECUTE, GROUP_READ,
       GROUP_WRITE, GROUP_EXECUTE, WORLD_READ, WORLD_WRITE, WORLD_EXECUTE,
       SETUID, and SETGID.  Permissions that do not make sense on certain
       platforms are ignored on those platforms.

       The CONFIGURATIONS argument specifies a list of build configurations
       for which the install rule applies (Debug, Release, etc.).

       The COMPONENT argument specifies an installation component name with
       which the install rule is associated, such as "runtime" or
       "development".  During component-specific installation only install
       rules associated with the given component name will be executed.
       During a full installation all components are installed.  If COMPONENT
       is not provided a default component "Unspecified" is created.  The
       default component name may be controlled with the
       CMAKE_INSTALL_DEFAULT_COMPONENT_NAME variable.

       The RENAME argument specifies a name for an installed file that may be
       different from the original file.  Renaming is allowed only when a
       single file is installed by the command.

       The OPTIONAL argument specifies that it is not an error if the file to
       be installed does not exist.

       The TARGETS signature:

         install(TARGETS targets... [EXPORT <export-name>]
                 [[ARCHIVE|LIBRARY|RUNTIME|FRAMEWORK|BUNDLE|
                   PRIVATE_HEADER|PUBLIC_HEADER|RESOURCE]
                  [DESTINATION <dir>]
                  [INCLUDES DESTINATION [<dir> ...]]
                  [PERMISSIONS permissions...]
                  [CONFIGURATIONS [Debug|Release|...]]
                  [COMPONENT <component>]
                  [OPTIONAL] [NAMELINK_ONLY|NAMELINK_SKIP]
                 ] [...])

       The TARGETS form specifies rules for installing targets from a
       project.  There are five kinds of target files that may be installed:
       ARCHIVE, LIBRARY, RUNTIME, FRAMEWORK, and BUNDLE.  Executables are
       treated as RUNTIME targets, except that those marked with the
       MACOSX_BUNDLE property are treated as BUNDLE targets on OS X.  Static
       libraries are always treated as ARCHIVE targets.  Module libraries are
       always treated as LIBRARY targets.  For non-DLL platforms shared
       libraries are treated as LIBRARY targets, except that those marked
       with the FRAMEWORK property are treated as FRAMEWORK targets on OS X.
       For DLL platforms the DLL part of a shared library is treated as a
       RUNTIME target and the corresponding import library is treated as an
       ARCHIVE target.  All Windows-based systems including Cygwin are DLL
       platforms.  The ARCHIVE, LIBRARY, RUNTIME, and FRAMEWORK arguments
       change the type of target to which the subsequent properties apply.
       If none is given the installation properties apply to all target
       types.  If only one is given then only targets of that type will be
       installed (which can be used to install just a DLL or just an import
       library).The INCLUDES DESTINATION specifies a list of directories
       which will be added to the INTERFACE_INCLUDE_DIRECTORIES of the
       <targets> when exported by install(EXPORT).  If a relative path is
       specified, it is treated as relative to the $<INSTALL_PREFIX>.

       The PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE arguments cause
       subsequent properties to be applied to installing a FRAMEWORK shared
       library target's associated files on non-Apple platforms.  Rules
       defined by these arguments are ignored on Apple platforms because the
       associated files are installed into the appropriate locations inside
       the framework folder.  See documentation of the PRIVATE_HEADER,
       PUBLIC_HEADER, and RESOURCE target properties for details.

       Either NAMELINK_ONLY or NAMELINK_SKIP may be specified as a LIBRARY
       option.  On some platforms a versioned shared library has a symbolic
       link such as

         lib<name>.so -> lib<name>.so.1

       where "lib<name>.so.1" is the soname of the library and "lib<name>.so"
       is a "namelink" allowing linkers to find the library when given
       "-l<name>".  The NAMELINK_ONLY option causes installation of only the
       namelink when a library target is installed.  The NAMELINK_SKIP option
       causes installation of library files other than the namelink when a
       library target is installed.  When neither option is given both
       portions are installed.  On platforms where versioned shared libraries
       do not have namelinks or when a library is not versioned the
       NAMELINK_SKIP option installs the library and the NAMELINK_ONLY option
       installs nothing.  See the VERSION and SOVERSION target properties for
       details on creating versioned shared libraries.

       One or more groups of properties may be specified in a single call to
       the TARGETS form of this command.  A target may be installed more than
       once to different locations.  Consider hypothetical targets "myExe",
       "mySharedLib", and "myStaticLib".  The code

           install(TARGETS myExe mySharedLib myStaticLib
                   RUNTIME DESTINATION bin
                   LIBRARY DESTINATION lib
                   ARCHIVE DESTINATION lib/static)
           install(TARGETS mySharedLib DESTINATION /some/full/path)

       will install myExe to <prefix>/bin and myStaticLib to
       <prefix>/lib/static.  On non-DLL platforms mySharedLib will be
       installed to <prefix>/lib and /some/full/path.  On DLL platforms the
       mySharedLib DLL will be installed to <prefix>/bin and /some/full/path
       and its import library will be installed to <prefix>/lib/static and
       /some/full/path.

       The EXPORT option associates the installed target files with an export
       called <export-name>.  It must appear before any RUNTIME, LIBRARY, or
       ARCHIVE options.  To actually install the export file itself, call
       install(EXPORT).  See documentation of the install(EXPORT ...)
       signature below for details.

       Installing a target with EXCLUDE_FROM_ALL set to true has undefined
       behavior.

       The FILES signature:

         install(FILES files... DESTINATION <dir>
                 [PERMISSIONS permissions...]
                 [CONFIGURATIONS [Debug|Release|...]]
                 [COMPONENT <component>]
                 [RENAME <name>] [OPTIONAL])

       The FILES form specifies rules for installing files for a project.
       File names given as relative paths are interpreted with respect to the
       current source directory.  Files installed by this form are by default
       given permissions OWNER_WRITE, OWNER_READ, GROUP_READ, and WORLD_READ
       if no PERMISSIONS argument is given.

       The PROGRAMS signature:

         install(PROGRAMS files... DESTINATION <dir>
                 [PERMISSIONS permissions...]
                 [CONFIGURATIONS [Debug|Release|...]]
                 [COMPONENT <component>]
                 [RENAME <name>] [OPTIONAL])

       The PROGRAMS form is identical to the FILES form except that the
       default permissions for the installed file also include OWNER_EXECUTE,
       GROUP_EXECUTE, and WORLD_EXECUTE.  This form is intended to install
       programs that are not targets, such as shell scripts.  Use the TARGETS
       form to install targets built within the project.

       The DIRECTORY signature:

         install(DIRECTORY dirs... DESTINATION <dir>
                 [FILE_PERMISSIONS permissions...]
                 [DIRECTORY_PERMISSIONS permissions...]
                 [USE_SOURCE_PERMISSIONS] [OPTIONAL]
                 [CONFIGURATIONS [Debug|Release|...]]
                 [COMPONENT <component>] [FILES_MATCHING]
                 [[PATTERN <pattern> | REGEX <regex>]
                  [EXCLUDE] [PERMISSIONS permissions...]] [...])

       The DIRECTORY form installs contents of one or more directories to a
       given destination.  The directory structure is copied verbatim to the
       destination.  The last component of each directory name is appended to
       the destination directory but a trailing slash may be used to avoid
       this because it leaves the last component empty.  Directory names
       given as relative paths are interpreted with respect to the current
       source directory.  If no input directory names are given the
       destination directory will be created but nothing will be installed
       into it.  The FILE_PERMISSIONS and DIRECTORY_PERMISSIONS options
       specify permissions given to files and directories in the destination.
       If USE_SOURCE_PERMISSIONS is specified and FILE_PERMISSIONS is not,
       file permissions will be copied from the source directory structure.
       If no permissions are specified files will be given the default
       permissions specified in the FILES form of the command, and the
       directories will be given the default permissions specified in the
       PROGRAMS form of the command.

       Installation of directories may be controlled with fine granularity
       using the PATTERN or REGEX options.  These "match" options specify a
       globbing pattern or regular expression to match directories or files
       encountered within input directories.  They may be used to apply
       certain options (see below) to a subset of the files and directories
       encountered.  The full path to each input file or directory (with
       forward slashes) is matched against the expression.  A PATTERN will
       match only complete file names: the portion of the full path matching
       the pattern must occur at the end of the file name and be preceded by
       a slash.  A REGEX will match any portion of the full path but it may
       use '/' and '$' to simulate the PATTERN behavior.  By default all
       files and directories are installed whether or not they are matched.
       The FILES_MATCHING option may be given before the first match option
       to disable installation of files (but not directories) not matched by
       any expression.  For example, the code

         install(DIRECTORY src/ DESTINATION include/myproj
                 FILES_MATCHING PATTERN "*.h")

       will extract and install header files from a source tree.

       Some options may follow a PATTERN or REGEX expression and are applied
       only to files or directories matching them.  The EXCLUDE option will
       skip the matched file or directory.  The PERMISSIONS option overrides
       the permissions setting for the matched file or directory.  For
       example the code

         install(DIRECTORY icons scripts/ DESTINATION share/myproj
                 PATTERN "CVS" EXCLUDE
                 PATTERN "scripts/*"
                 PERMISSIONS OWNER_EXECUTE OWNER_WRITE OWNER_READ
                             GROUP_EXECUTE GROUP_READ)

       will install the icons directory to share/myproj/icons and the scripts
       directory to share/myproj.  The icons will get default file
       permissions, the scripts will be given specific permissions, and any
       CVS directories will be excluded.

       The SCRIPT and CODE signature:

         install([[SCRIPT <file>] [CODE <code>]] [...])

       The SCRIPT form will invoke the given CMake script files during
       installation.  If the script file name is a relative path it will be
       interpreted with respect to the current source directory.  The CODE
       form will invoke the given CMake code during installation.  Code is
       specified as a single argument inside a double-quoted string.  For
       example, the code

         install(CODE "MESSAGE(\"Sample install message.\")")

       will print a message during installation.

       The EXPORT signature:

         install(EXPORT <export-name> DESTINATION <dir>
                 [NAMESPACE <namespace>] [FILE <name>.cmake]
                 [PERMISSIONS permissions...]
                 [CONFIGURATIONS [Debug|Release|...]]
                 [EXPORT_LINK_INTERFACE_LIBRARIES]
                 [COMPONENT <component>])

       The EXPORT form generates and installs a CMake file containing code to
       import targets from the installation tree into another project.
       Target installations are associated with the export <export-name>
       using the EXPORT option of the install(TARGETS ...) signature
       documented above.  The NAMESPACE option will prepend <namespace> to
       the target names as they are written to the import file.  By default
       the generated file will be called <export-name>.cmake but the FILE
       option may be used to specify a different name.  The value given to
       the FILE option must be a file name with the ".cmake" extension.  If a
       CONFIGURATIONS option is given then the file will only be installed
       when one of the named configurations is installed.  Additionally, the
       generated import file will reference only the matching target
       configurations.  The EXPORT_LINK_INTERFACE_LIBRARIES keyword, if
       present, causes the contents of the properties matching
       (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)? to be exported, when
       policy CMP0022 is NEW.  If a COMPONENT option is specified that does
       not match that given to the targets associated with <export-name> the
       behavior is undefined.  If a library target is included in the export
       but a target to which it links is not included the behavior is
       unspecified.

       The EXPORT form is useful to help outside projects use targets built
       and installed by the current project.  For example, the code

         install(TARGETS myexe EXPORT myproj DESTINATION bin)
         install(EXPORT myproj NAMESPACE mp_ DESTINATION lib/myproj)

       will install the executable myexe to <prefix>/bin and code to import
       it in the file "<prefix>/lib/myproj/myproj.cmake".  An outside project
       may load this file with the include command and reference the myexe
       executable from the installation tree using the imported target name
       mp_myexe as if the target were built in its own tree.

       NOTE: This command supercedes the INSTALL_TARGETS command and the
       target properties PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT.  It also
       replaces the FILES forms of the INSTALL_FILES and INSTALL_PROGRAMS
       commands.  The processing order of these install rules relative to
       those generated by INSTALL_TARGETS, INSTALL_FILES, and
       INSTALL_PROGRAMS commands is not defined.


  link_directories
       Specify directories in which the linker will look for libraries.

         link_directories(directory1 directory2 ...)

       Specify the paths in which the linker should search for libraries.
       The command will apply only to targets created after it is called.
       Relative paths given to this command are interpreted as relative to
       the current source directory, see CMP0015.

       Note that this command is rarely necessary.  Library locations
       returned by find_package() and find_library() are absolute paths.
       Pass these absolute library file paths directly to the
       target_link_libraries() command.  CMake will ensure the linker finds
       them.

  list
       List operations.

         list(LENGTH <list> <output variable>)
         list(GET <list> <element index> [<element index> ...]
              <output variable>)
         list(APPEND <list> <element> [<element> ...])
         list(FIND <list> <value> <output variable>)
         list(INSERT <list> <element_index> <element> [<element> ...])
         list(REMOVE_ITEM <list> <value> [<value> ...])
         list(REMOVE_AT <list> <index> [<index> ...])
         list(REMOVE_DUPLICATES <list>)
         list(REVERSE <list>)
         list(SORT <list>)

       LENGTH will return a given list's length.

       GET will return list of elements specified by indices from the list.

       APPEND will append elements to the list.

       FIND will return the index of the element specified in the list or -1
       if it wasn't found.

       INSERT will insert elements to the list to the specified location.

       REMOVE_AT and REMOVE_ITEM will remove items from the list.  The
       difference is that REMOVE_ITEM will remove the given items, while
       REMOVE_AT will remove the items at the given indices.

       REMOVE_DUPLICATES will remove duplicated items in the list.

       REVERSE reverses the contents of the list in-place.

       SORT sorts the list in-place alphabetically.

       The list subcommands APPEND, INSERT, REMOVE_AT, REMOVE_ITEM,
       REMOVE_DUPLICATES, REVERSE and SORT may create new values for the list
       within the current CMake variable scope.  Similar to the SET command,
       the LIST command creates new variable values in the current scope,
       even if the list itself is actually defined in a parent scope.  To
       propagate the results of these operations upwards, use SET with
       PARENT_SCOPE, SET with CACHE INTERNAL, or some other means of value
       propagation.

       NOTES: A list in cmake is a ; separated group of strings.  To create a
       list the set command can be used.  For example, set(var a b c d e)
       creates a list with a;b;c;d;e, and set(var "a b c d e") creates a
       string or a list with one item in it.

       When specifying index values, if <element index> is 0 or greater, it
       is indexed from the beginning of the list, with 0 representing the
       first list element.  If <element index> is -1 or lesser, it is indexed
       from the end of the list, with -1 representing the last list element.
       Be careful when counting with negative indices: they do not start from
       0.  -0 is equivalent to 0, the first list element.


  load_cache
       Load in the values from another project's CMake cache.

         load_cache(pathToCacheFile READ_WITH_PREFIX
                    prefix entry1...)

       Read the cache and store the requested entries in variables with their
       name prefixed with the given prefix.  This only reads the values, and
       does not create entries in the local project's cache.

         load_cache(pathToCacheFile [EXCLUDE entry1...]
                    [INCLUDE_INTERNALS entry1...])

       Load in the values from another cache and store them in the local
       project's cache as internal entries.  This is useful for a project
       that depends on another project built in a different tree.  EXCLUDE
       option can be used to provide a list of entries to be excluded.
       INCLUDE_INTERNALS can be used to provide a list of internal entries to
       be included.  Normally, no internal entries are brought in.  Use of
       this form of the command is strongly discouraged, but it is provided
       for backward compatibility.

  load_command
       Load a command into a running CMake.

         load_command(COMMAND_NAME <loc1> [loc2 ...])

       The given locations are searched for a library whose name is
       cmCOMMAND_NAME.  If found, it is loaded as a module and the command is
       added to the set of available CMake commands.  Usually, TRY_COMPILE is
       used before this command to compile the module.  If the command is
       successfully loaded a variable named

         CMAKE_LOADED_COMMAND_<COMMAND_NAME>

       will be set to the full path of the module that was loaded.  Otherwise
       the variable will not be set.

  macro
       Start recording a macro for later invocation as a command.

         macro(<name> [arg1 [arg2 [arg3 ...]]])
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         endmacro(<name>)

       Define a macro named <name> that takes arguments named arg1 arg2 arg3
       (...).  Commands listed after macro, but before the matching endmacro,
       are not invoked until the macro is invoked.  When it is invoked, the
       commands recorded in the macro are first modified by replacing formal
       parameters (${arg1}) with the arguments passed, and then invoked as
       normal commands.  In addition to referencing the formal parameters you
       can reference the values ${ARGC} which will be set to the number of
       arguments passed into the function as well as ${ARGV0} ${ARGV1}
       ${ARGV2} ...  which will have the actual values of the arguments
       passed in.  This facilitates creating macros with optional arguments.
       Additionally ${ARGV} holds the list of all arguments given to the
       macro and ${ARGN} holds the list of arguments past the last expected
       argument.  Note that the parameters to a macro and values such as ARGN
       are not variables in the usual CMake sense.  They are string
       replacements much like the C preprocessor would do with a macro.  If
       you want true CMake variables and/or better CMake scope control you
       should look at the function command.

       See the cmake_policy() command documentation for the behavior of
       policies inside macros.

  mark_as_advanced
       Mark cmake cached variables as advanced.

         mark_as_advanced([CLEAR|FORCE] VAR VAR2 VAR...)

       Mark the named cached variables as advanced.  An advanced variable
       will not be displayed in any of the cmake GUIs unless the show
       advanced option is on.  If CLEAR is the first argument advanced
       variables are changed back to unadvanced.  If FORCE is the first
       argument, then the variable is made advanced.  If neither FORCE nor
       CLEAR is specified, new values will be marked as advanced, but if the
       variable already has an advanced/non-advanced state, it will not be
       changed.

       It does nothing in script mode.

  math
       Mathematical expressions.

         math(EXPR <output variable> <math expression>)

       EXPR evaluates mathematical expression and returns result in the
       output variable.  Example mathematical expression is '5 * ( 10 + 13
       )'.  Supported operators are + - * / % | & ^ ~ << >> * / %.  They have
       the same meaning as they do in C code.

  message
       Display a message to the user.

         message([STATUS|WARNING|AUTHOR_WARNING|FATAL_ERROR|SEND_ERROR]
                 "message to display" ...)

       The optional keyword determines the type of message:

         (none)         = Important information
         STATUS         = Incidental information
         WARNING        = CMake Warning, continue processing
         AUTHOR_WARNING = CMake Warning (dev), continue processing
         SEND_ERROR     = CMake Error, continue processing,
                                       but skip generation
         FATAL_ERROR    = CMake Error, stop processing and generation

       The CMake command-line tool displays STATUS messages on stdout and all
       other message types on stderr.  The CMake GUI displays all messages in
       its log area.  The interactive dialogs (ccmake and CMakeSetup) show
       STATUS messages one at a time on a status line and other messages in
       interactive pop-up boxes.

       CMake Warning and Error message text displays using a simple markup
       language.  Non-indented text is formatted in line-wrapped paragraphs
       delimited by newlines.  Indented text is considered pre-formatted.

  option
       Provides an option that the user can optionally select.

         option(<option_variable> "help string describing option"
                [initial value])

       Provide an option for the user to select as ON or OFF.  If no initial
       value is provided, OFF is used.

       If you have options that depend on the values of other options, see
       the module help for CMakeDependentOption.

  project
       Set a name for the entire project.

         project(<projectname> [languageName1 languageName2 ... ] )

       Sets the name of the project.  Additionally this sets the variables
       <projectName>_BINARY_DIR and <projectName>_SOURCE_DIR to the
       respective values.

       Optionally you can specify which languages your project supports.
       Example languages are CXX (i.e.  C++), C, Fortran, etc.  By default C
       and CXX are enabled.  E.g.  if you do not have a C++ compiler, you can
       disable the check for it by explicitly listing the languages you want
       to support, e.g.  C.  By using the special language "NONE" all checks
       for any language can be disabled.  If a variable exists called
       CMAKE_PROJECT_<projectName>_INCLUDE, the file pointed to by that
       variable will be included as the last step of the project command.

       The top-level CMakeLists.txt file for a project must contain a
       literal, direct call to the project() command; loading one through the
       include() command is not sufficient.  If no such call exists CMake
       will implicitly add one to the top that enables the default languages
       (C and CXX).

  qt_wrap_cpp
       Create Qt Wrappers.

         qt_wrap_cpp(resultingLibraryName DestName
                     SourceLists ...)

       Produce moc files for all the .h files listed in the SourceLists.  The
       moc files will be added to the library using the DestName source list.

  qt_wrap_ui
       Create Qt user interfaces Wrappers.

         qt_wrap_ui(resultingLibraryName HeadersDestName
                    SourcesDestName SourceLists ...)

       Produce .h and .cxx files for all the .ui files listed in the
       SourceLists.  The .h files will be added to the library using the
       HeadersDestNamesource list.  The .cxx files will be added to the
       library using the SourcesDestNamesource list.

  remove_definitions
       Removes -D define flags added by add_definitions.

         remove_definitions(-DFOO -DBAR ...)

       Removes flags (added by add_definitions) from the compiler command
       line for sources in the current directory and below.

  return
       Return from a file, directory or function.

         return()

       Returns from a file, directory or function.  When this command is
       encountered in an included file (via include() or find_package()), it
       causes processing of the current file to stop and control is returned
       to the including file.  If it is encountered in a file which is not
       included by another file, e.g.  a CMakeLists.txt, control is returned
       to the parent directory if there is one.  If return is called in a
       function, control is returned to the caller of the function.  Note
       that a macro is not a function and does not handle return like a
       function does.

  separate_arguments
       Parse space-separated arguments into a semicolon-separated list.

         separate_arguments(<var> <UNIX|WINDOWS>_COMMAND "<args>")

       Parses a unix- or windows-style command-line string "<args>" and
       stores a semicolon-separated list of the arguments in <var>.  The
       entire command line must be given in one "<args>" argument.

       The UNIX_COMMAND mode separates arguments by unquoted whitespace.  It
       recognizes both single-quote and double-quote pairs.  A backslash
       escapes the next literal character (\" is "); there are no special
       escapes (\n is just n).

       The WINDOWS_COMMAND mode parses a windows command-line using the same
       syntax the runtime library uses to construct argv at startup.  It
       separates arguments by whitespace that is not double-quoted.
       Backslashes are literal unless they precede double-quotes.  See the
       MSDN article "Parsing C Command-Line Arguments" for details.

         separate_arguments(VARIABLE)

       Convert the value of VARIABLE to a semi-colon separated list.  All
       spaces are replaced with ';'.  This helps with generating command
       lines.

  set
       Set a CMake, cache or environment variable to a given value.

         set(<variable> <value>
             [[CACHE <type> <docstring> [FORCE]] | PARENT_SCOPE])

       Within CMake sets <variable> to the value <value>.  <value> is
       expanded before <variable> is set to it.  Normally, set will set a
       regular CMake variable.  If CACHE is present, then the <variable> is
       put in the cache instead, unless it is already in the cache.  See
       section 'Variable types in CMake' below for details of regular and
       cache variables and their interactions.  If CACHE is used, <type> and
       <docstring> are required.  <type> is used by the CMake GUI to choose a
       widget with which the user sets a value.  The value for <type> may be
       one of

         FILEPATH = File chooser dialog.
         PATH     = Directory chooser dialog.
         STRING   = Arbitrary string.
         BOOL     = Boolean ON/OFF checkbox.
         INTERNAL = No GUI entry (used for persistent variables).

       If <type> is INTERNAL, the cache variable is marked as internal, and
       will not be shown to the user in tools like cmake-gui.  This is
       intended for values that should be persisted in the cache, but which
       users should not normally change.  INTERNAL implies FORCE.

       Normally, set(...CACHE...) creates cache variables, but does not
       modify them.  If FORCE is specified, the value of the cache variable
       is set, even if the variable is already in the cache.  This should
       normally be avoided, as it will remove any changes to the cache
       variable's value by the user.

       If PARENT_SCOPE is present, the variable will be set in the scope
       above the current scope.  Each new directory or function creates a new
       scope.  This command will set the value of a variable into the parent
       directory or calling function (whichever is applicable to the case at
       hand).  PARENT_SCOPE cannot be combined with CACHE.

       If <value> is not specified then the variable is removed instead of
       set.  See also: the unset() command.

         set(<variable> <value1> ... <valueN>)

       In this case <variable> is set to a semicolon separated list of
       values.

       <variable> can be an environment variable such as:

         set( ENV{PATH} /home/martink )

       in which case the environment variable will be set.

       *** Variable types in CMake ***

       In CMake there are two types of variables: normal variables and cache
       variables.  Normal variables are meant for the internal use of the
       script (just like variables in most programming languages); they are
       not persisted across CMake runs.  Cache variables (unless set with
       INTERNAL) are mostly intended for configuration settings where the
       first CMake run determines a suitable default value, which the user
       can then override, by editing the cache with tools such as ccmake or
       cmake-gui.  Cache variables are stored in the CMake cache file, and
       are persisted across CMake runs.

       Both types can exist at the same time with the same name but different
       values.  When ${FOO} is evaluated, CMake first looks for a normal
       variable 'FOO' in scope and uses it if set.  If and only if no normal
       variable exists then it falls back to the cache variable 'FOO'.

       Some examples:

       The code 'set(FOO "x")' sets the normal variable 'FOO'.  It does not
       touch the cache, but it will hide any existing cache value 'FOO'.

       The code 'set(FOO "x" CACHE ...)' checks for 'FOO' in the cache,
       ignoring any normal variable of the same name.  If 'FOO' is in the
       cache then nothing happens to either the normal variable or the cache
       variable.  If 'FOO' is not in the cache, then it is added to the
       cache.

       Finally, whenever a cache variable is added or modified by a command,
       CMake also *removes* the normal variable of the same name from the
       current scope so that an immediately following evaluation of it will
       expose the newly cached value.

       Normally projects should avoid using normal and cache variables of the
       same name, as this interaction can be hard to follow.  However, in
       some situations it can be useful.  One example (used by some
       projects):

       A project has a subproject in its source tree.  The child project has
       its own CMakeLists.txt, which is included from the parent
       CMakeLists.txt using add_subdirectory().  Now, if the parent and the
       child project provide the same option (for example a compiler option),
       the parent gets the first chance to add a user-editable option to the
       cache.  Normally, the child would then use the same value that the
       parent uses.  However, it may be necessary to hard-code the value for
       the child project's option while still allowing the user to edit the
       value used by the parent project.  The parent project can achieve this
       simply by setting a normal variable with the same name as the option
       in a scope sufficient to hide the option's cache variable from the
       child completely.  The parent has already set the cache variable, so
       the child's set(...CACHE...) will do nothing, and evaluating the
       option variable will use the value from the normal variable, which
       hides the cache variable.

  set_directory_properties
       Set a property of the directory.

         set_directory_properties(PROPERTIES prop1 value1 prop2 value2)

       Set a property for the current directory and subdirectories.  If the
       property is not found, CMake will report an error.  The properties
       include: INCLUDE_DIRECTORIES, LINK_DIRECTORIES,
       INCLUDE_REGULAR_EXPRESSION, and ADDITIONAL_MAKE_CLEAN_FILES.
       ADDITIONAL_MAKE_CLEAN_FILES is a list of files that will be cleaned as
       a part of "make clean" stage.

  set_property
       Set a named property in a given scope.

         set_property(<GLOBAL                            |
                       DIRECTORY [dir]                   |
                       TARGET    [target1 [target2 ...]] |
                       SOURCE    [src1 [src2 ...]]       |
                       TEST      [test1 [test2 ...]]     |
                       CACHE     [entry1 [entry2 ...]]>
                      [APPEND] [APPEND_STRING]
                      PROPERTY <name> [value1 [value2 ...]])

       Set one property on zero or more objects of a scope.  The first
       argument determines the scope in which the property is set.  It must
       be one of the following:

       GLOBAL scope is unique and does not accept a name.

       DIRECTORY scope defaults to the current directory but another
       directory (already processed by CMake) may be named by full or
       relative path.

       TARGET scope may name zero or more existing targets.

       SOURCE scope may name zero or more source files.  Note that source
       file properties are visible only to targets added in the same
       directory (CMakeLists.txt).

       TEST scope may name zero or more existing tests.

       CACHE scope must name zero or more cache existing entries.

       The required PROPERTY option is immediately followed by the name of
       the property to set.  Remaining arguments are used to compose the
       property value in the form of a semicolon-separated list.  If the
       APPEND option is given the list is appended to any existing property
       value.If the APPEND_STRING option is given the string is append to any
       existing property value as string, i.e.  it results in a longer string
       and not a list of strings.

  set_source_files_properties
       Source files can have properties that affect how they are built.

         set_source_files_properties([file1 [file2 [...]]]
                                     PROPERTIES prop1 value1
                                     [prop2 value2 [...]])

       Set properties associated with source files using a key/value paired
       list.  See properties documentation for those known to CMake.
       Unrecognized properties are ignored.  Source file properties are
       visible only to targets added in the same directory (CMakeLists.txt).

  set_target_properties
       Targets can have properties that affect how they are built.

         set_target_properties(target1 target2 ...
                               PROPERTIES prop1 value1
                               prop2 value2 ...)

       Set properties on a target.  The syntax for the command is to list all
       the files you want to change, and then provide the values you want to
       set next.  You can use any prop value pair you want and extract it
       later with the GET_TARGET_PROPERTY command.

       Properties that affect the name of a target's output file are as
       follows.  The PREFIX and SUFFIX properties override the default target
       name prefix (such as "lib") and suffix (such as ".so").  IMPORT_PREFIX
       and IMPORT_SUFFIX are the equivalent properties for the import library
       corresponding to a DLL (for SHARED library targets).  OUTPUT_NAME sets
       the real name of a target when it is built and can be used to help
       create two targets of the same name even though CMake requires unique
       logical target names.  There is also a <CONFIG>_OUTPUT_NAME that can
       set the output name on a per-configuration basis.  <CONFIG>_POSTFIX
       sets a postfix for the real name of the target when it is built under
       the configuration named by <CONFIG> (in upper-case, such as
       "DEBUG_POSTFIX").  The value of this property is initialized when the
       target is created to the value of the variable CMAKE_<CONFIG>_POSTFIX
       (except for executable targets because earlier CMake versions which
       did not use this variable for executables).

       The LINK_FLAGS property can be used to add extra flags to the link
       step of a target.  LINK_FLAGS_<CONFIG> will add to the configuration
       <CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO.
       DEFINE_SYMBOL sets the name of the preprocessor symbol defined when
       compiling sources in a shared library.  If not set here then it is set
       to target_EXPORTS by default (with some substitutions if the target is
       not a valid C identifier).  This is useful for headers to know whether
       they are being included from inside their library or outside to
       properly setup dllexport/dllimport decorations.  The COMPILE_FLAGS
       property sets additional compiler flags used to build sources within
       the target.  It may also be used to pass additional preprocessor
       definitions.

       The LINKER_LANGUAGE property is used to change the tool used to link
       an executable or shared library.  The default is set the language to
       match the files in the library.  CXX and C are common values for this
       property.

       For shared libraries VERSION and SOVERSION can be used to specify the
       build version and API version respectively.  When building or
       installing appropriate symlinks are created if the platform supports
       symlinks and the linker supports so-names.  If only one of both is
       specified the missing is assumed to have the same version number.  For
       executables VERSION can be used to specify the build version.  When
       building or installing appropriate symlinks are created if the
       platform supports symlinks.  For shared libraries and executables on
       Windows the VERSION attribute is parsed to extract a "major.minor"
       version number.  These numbers are used as the image version of the
       binary.

       There are a few properties used to specify RPATH rules.  INSTALL_RPATH
       is a semicolon-separated list specifying the rpath to use in installed
       targets (for platforms that support it).  INSTALL_RPATH_USE_LINK_PATH
       is a boolean that if set to true will append directories in the linker
       search path and outside the project to the INSTALL_RPATH.
       SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic
       generation of an rpath allowing the target to run from the build tree.
       BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the
       target in the build tree with the INSTALL_RPATH.  This takes
       precedence over SKIP_BUILD_RPATH and avoids the need for relinking
       before installation.  INSTALL_NAME_DIR is a string specifying the
       directory portion of the "install_name" field of shared libraries on
       Mac OSX to use in the installed targets.  When the target is created
       the values of the variables CMAKE_INSTALL_RPATH,
       CMAKE_INSTALL_RPATH_USE_LINK_PATH, CMAKE_SKIP_BUILD_RPATH,
       CMAKE_BUILD_WITH_INSTALL_RPATH, and CMAKE_INSTALL_NAME_DIR are used to
       initialize these properties.

       PROJECT_LABEL can be used to change the name of the target in an IDE
       like visual studio.  VS_KEYWORD can be set to change the visual studio
       keyword, for example Qt integration works better if this is set to
       Qt4VSv1.0.

       VS_SCC_PROJECTNAME, VS_SCC_LOCALPATH, VS_SCC_PROVIDER and
       VS_SCC_AUXPATH can be set to add support for source control bindings
       in a Visual Studio project file.

       VS_GLOBAL_<variable> can be set to add a Visual Studio
       project-specific global variable.  Qt integration works better if
       VS_GLOBAL_QtVersion is set to the Qt version FindQt4.cmake found.  For
       example, "4.7.3"

       The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
       way to specify CMake scripts to run before and after installing a
       target.  They are used only when the old INSTALL_TARGETS command is
       used to install the target.  Use the INSTALL command instead.

       The EXCLUDE_FROM_DEFAULT_BUILD property is used by the visual studio
       generators.  If it is set to 1 the target will not be part of the
       default build when you select "Build Solution".  This can also be set
       on a per-configuration basis using
       EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG>.

  set_tests_properties
       Set a property of the tests.

         set_tests_properties(test1 [test2...] PROPERTIES prop1 value1 prop2 value2)

       Set a property for the tests.  If the property is not found, CMake
       will report an error.  The properties include:

       WILL_FAIL: If set to true, this will invert the pass/fail flag of the
       test.

       PASS_REGULAR_EXPRESSION: If set, the test output will be checked
       against the specified regular expressions and at least one of the
       regular expressions has to match, otherwise the test will fail.

         Example: PASS_REGULAR_EXPRESSION "TestPassed;All ok"

       FAIL_REGULAR_EXPRESSION: If set, if the output will match to one of
       specified regular expressions, the test will fail.

         Example: PASS_REGULAR_EXPRESSION "[^a-z]Error;ERROR;Failed"

       Both PASS_REGULAR_EXPRESSION and FAIL_REGULAR_EXPRESSION expect a list
       of regular expressions.

       TIMEOUT: Setting this will limit the test runtime to the number of
       seconds specified.


  site_name
       Set the given variable to the name of the computer.

         site_name(variable)


  source_group
       Define a grouping for sources in the makefile.

         source_group(name [REGULAR_EXPRESSION regex] [FILES src1 src2 ...])

       Defines a group into which sources will be placed in project files.
       This is mainly used to setup file tabs in Visual Studio.  Any file
       whose name is listed or matches the regular expression will be placed
       in this group.  If a file matches multiple groups, the LAST group that
       explicitly lists the file will be favored, if any.  If no group
       explicitly lists the file, the LAST group whose regular expression
       matches the file will be favored.

       The name of the group may contain backslashes to specify subgroups:

         source_group(outer\\inner ...)

       For backwards compatibility, this command also supports the format:

         source_group(name regex)

  string
       String operations.

         string(REGEX MATCH <regular_expression>
                <output variable> <input> [<input>...])
         string(REGEX MATCHALL <regular_expression>
                <output variable> <input> [<input>...])
         string(REGEX REPLACE <regular_expression>
                <replace_expression> <output variable>
                <input> [<input>...])
         string(REPLACE <match_string>
                <replace_string> <output variable>
                <input> [<input>...])
         string(<MD5|SHA1|SHA224|SHA256|SHA384|SHA512>
                <output variable> <input>)
         string(COMPARE EQUAL <string1> <string2> <output variable>)
         string(COMPARE NOTEQUAL <string1> <string2> <output variable>)
         string(COMPARE LESS <string1> <string2> <output variable>)
         string(COMPARE GREATER <string1> <string2> <output variable>)
         string(ASCII <number> [<number> ...] <output variable>)
         string(CONFIGURE <string1> <output variable>
                [@ONLY] [ESCAPE_QUOTES])
         string(TOUPPER <string1> <output variable>)
         string(TOLOWER <string1> <output variable>)
         string(LENGTH <string> <output variable>)
         string(SUBSTRING <string> <begin> <length> <output variable>)
         string(STRIP <string> <output variable>)
         string(RANDOM [LENGTH <length>] [ALPHABET <alphabet>]
                [RANDOM_SEED <seed>] <output variable>)
         string(FIND <string> <substring> <output variable> [REVERSE])
         string(TIMESTAMP <output variable> [<format string>] [UTC])
         string(MAKE_C_IDENTIFIER <input string> <output variable>)

       REGEX MATCH will match the regular expression once and store the match
       in the output variable.

       REGEX MATCHALL will match the regular expression as many times as
       possible and store the matches in the output variable as a list.

       REGEX REPLACE will match the regular expression as many times as
       possible and substitute the replacement expression for the match in
       the output.  The replace expression may refer to paren-delimited
       subexpressions of the match using \1, \2, ..., \9.  Note that two
       backslashes (\\1) are required in CMake code to get a backslash
       through argument parsing.

       REPLACE will replace all occurrences of match_string in the input with
       replace_string and store the result in the output.

       MD5, SHA1, SHA224, SHA256, SHA384, and SHA512 will compute a
       cryptographic hash of the input string.

       COMPARE EQUAL/NOTEQUAL/LESS/GREATER will compare the strings and store
       true or false in the output variable.

       ASCII will convert all numbers into corresponding ASCII characters.

       CONFIGURE will transform a string like CONFIGURE_FILE transforms a
       file.

       TOUPPER/TOLOWER will convert string to upper/lower characters.

       LENGTH will return a given string's length.

       SUBSTRING will return a substring of a given string.  If length is -1
       the remainder of the string starting at begin will be returned.

       STRIP will return a substring of a given string with leading and
       trailing spaces removed.

       RANDOM will return a random string of given length consisting of
       characters from the given alphabet.  Default length is 5 characters
       and default alphabet is all numbers and upper and lower case letters.
       If an integer RANDOM_SEED is given, its value will be used to seed the
       random number generator.

       FIND will return the position where the given substring was found in
       the supplied string.  If the REVERSE flag was used, the command will
       search for the position of the last occurrence of the specified
       substring.

       The following characters have special meaning in regular expressions:

          ^         Matches at beginning of input
          $         Matches at end of input
          .         Matches any single character
          [ ]       Matches any character(s) inside the brackets
          [^ ]      Matches any character(s) not inside the brackets
           -        Inside brackets, specifies an inclusive range between
                    characters on either side e.g. [a-f] is [abcdef]
                    To match a literal - using brackets, make it the first
                    or the last character e.g. [+*/-] matches basic
                    mathematical operators.
          *         Matches preceding pattern zero or more times
          +         Matches preceding pattern one or more times
          ?         Matches preceding pattern zero or once only
          |         Matches a pattern on either side of the |
          ()        Saves a matched subexpression, which can be referenced 
                    in the REGEX REPLACE operation. Additionally it is saved
                    by all regular expression-related commands, including 
                    e.g. if( MATCHES ), in the variables CMAKE_MATCH_(0..9).

       *, + and ? have higher precedence than concatenation.  | has lower
       precedence than concatenation.  This means that the regular expression
       "^ab+d$" matches "abbd" but not "ababd", and the regular expression
       "^(ab|cd)$" matches "ab" but not "abd".

       TIMESTAMP will write a string representation of the current date
       and/or time to the output variable.

       Should the command be unable to obtain a timestamp the output variable
       will be set to the empty string "".

       The optional UTC flag requests the current date/time representation to
       be in Coordinated Universal Time (UTC) rather than local time.

       The optional <format string> may contain the following format
       specifiers:

          %d        The day of the current month (01-31).
          %H        The hour on a 24-hour clock (00-23).
          %I        The hour on a 12-hour clock (01-12).
          %j        The day of the current year (001-366).
          %m        The month of the current year (01-12).
          %M        The minute of the current hour (00-59).
          %S        The second of the current minute.
                    60 represents a leap second. (00-60)
          %U        The week number of the current year (00-53).
          %w        The day of the current week. 0 is Sunday. (0-6)
          %y        The last two digits of the current year (00-99)
          %Y        The current year. 

       Unknown format specifiers will be ignored and copied to the output
       as-is.

       If no explicit <format string> is given it will default to:

          %Y-%m-%dT%H:%M:%S    for local time.
          %Y-%m-%dT%H:%M:%SZ   for UTC.

       MAKE_C_IDENTIFIER will write a string which can be used as an
       identifier in C.

  target_compile_definitions
       Add compile definitions to a target.

         target_compile_definitions(<target> <INTERFACE|PUBLIC|PRIVATE> [items1...]
           [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...])

       Specify compile definitions to use when compiling a given target.  The
       named <target> must have been created by a command such as
       add_executable or add_library and must not be an IMPORTED target.  The
       INTERFACE, PUBLIC and PRIVATE keywords are required to specify the
       scope of the following arguments.  PRIVATE and PUBLIC items will
       populate the COMPILE_DEFINITIONS property of <target>.  PUBLIC and
       INTERFACE items will populate the INTERFACE_COMPILE_DEFINITIONS
       property of <target>.  The following arguments specify compile
       definitions.  Repeated calls for the same <target> append items in the
       order called.

       Arguments to target_compile_definitions may use "generator
       expressions" with the syntax "$<...>".  Generator expressions are
       evaluated during build system generation to produce information

         target_compile_options(<target> [BEFORE] <INTERFACE|PUBLIC|PRIVATE> [items1...]
           [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...])

       Specify compile options to use when compiling a given target.  The
       named <target> must have been created by a command such as
       add_executable or add_library and must not be an IMPORTED target.  If
       BEFORE is specified, the content will be prepended to the property
       instead of being appended.

       The INTERFACE, PUBLIC and PRIVATE keywords are required to specify the
       scope of the following arguments.  PRIVATE and PUBLIC items will
       populate the COMPILE_OPTIONS property of <target>.  PUBLIC and
       INTERFACE items will populate the INTERFACE_COMPILE_OPTIONS property
       of <target>.  The following arguments specify compile opitions.
       Repeated calls for the same <target> append items in the order called.

       Arguments to target_compile_options may use "generator expressions"
       with the syntax "$<...>".  Generator expressions are evaluated during

  target_include_directories
       Add include directories to a target.

         target_include_directories(<target> [SYSTEM] [BEFORE] <INTERFACE|PUBLIC|PRIVATE> [items1...]
           [<INTERFACE|PUBLIC|PRIVATE> [items2...] ...])

       Specify include directories or targets to use when compiling a given
       target.  The named <target> must have been created by a command such
       as add_executable or add_library and must not be an IMPORTED target.

       If BEFORE is specified, the content will be prepended to the property
       instead of being appended.

       The INTERFACE, PUBLIC and PRIVATE keywords are required to specify the
       scope of the following arguments.  PRIVATE and PUBLIC items will
       populate the INCLUDE_DIRECTORIES property of <target>.  PUBLIC and
       INTERFACE items will populate the INTERFACE_INCLUDE_DIRECTORIES
       property of <target>.  The following arguments specify include
       directories.  Specified include directories may be absolute paths or
       relative paths.  Repeated calls for the same <target> append items in
       the order called.If SYSTEM is specified, the compiler will be told the
       directories are meant as system include directories on some platforms
       (signalling this setting might achieve effects such as the compiler
       skipping warnings, or these fixed-install system files not being
       considered in dependency calculations - see compiler docs).  If SYSTEM
       is used together with PUBLIC or INTERFACE, the
       INTERFACE_SYSTEM_INCLUDE_DIRECTORIES target property will be populated
       with the specified directories.

       Arguments to target_include_directories may use "generator
       expressions" with the syntax "$<...>".  Generator expressions are
       evaluated during build system generation to produce information

       Expressions with an implicit 'this' target:

         $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.


  target_link_libraries
       Link a target to given libraries.

         target_link_libraries(<target> [item1 [item2 [...]]]
                               [[debug|optimized|general] <item>] ...)

       Specify libraries or flags to use when linking a given target.  The
       named <target> must have been created in the current directory by a
       command such as add_executable or add_library.  The remaining
       arguments specify library names or flags.  Repeated calls for the same
       <target> append items in the order called.

       If a library name matches that of another target in the project a
       dependency will automatically be added in the build system to make
       sure the library being linked is up-to-date before the target links.
       Item names starting with '-', but not '-l' or '-framework', are
       treated as linker flags.

       A "debug", "optimized", or "general" keyword indicates that the
       library immediately following it is to be used only for the
       corresponding build configuration.  The "debug" keyword corresponds to
       the Debug configuration (or to configurations named in the
       DEBUG_CONFIGURATIONS global property if it is set).  The "optimized"
       keyword corresponds to all other configurations.  The "general"
       keyword corresponds to all configurations, and is purely optional
       (assumed if omitted).  Higher granularity may be achieved for
       per-configuration rules by creating and linking to IMPORTED library
       targets.  See the IMPORTED mode of the add_library command for more
       information.

       Library dependencies are transitive by default with this signature.
       When this target is linked into another target then the libraries
       linked to this target will appear on the link line for the other
       target too.  This transitive "link interface" is stored in the
       INTERFACE_LINK_LIBRARIES target property when policy CMP0022 is set to
       NEW and may be overridden by setting the property directly.  (When
       CMP0022 is not set to NEW, transitive linking is builtin but may be
       overridden by the LINK_INTERFACE_LIBRARIES property.  Calls to other
       signatures of this command may set the property making any libraries
       linked exclusively by this signature private.)

       CMake will also propagate "usage requirements" from linked library
       targets.  Usage requirements affect compilation of sources in the
       <target>.  They are specified by properties defined on linked targets.
       During generation of the build system, CMake integrates usage
       requirement property values with the corresponding build properties
       for <target>:

        INTERFACE_COMPILE_DEFINITONS: Appends to COMPILE_DEFINITONS
        INTERFACE_INCLUDE_DIRECTORIES: Appends to INCLUDE_DIRECTORIES
        INTERFACE_POSITION_INDEPENDENT_CODE: Sets POSITION_INDEPENDENT_CODE
          or checked for consistency with existing value

       

       If an <item> is a library in a Mac OX framework, the Headers directory
       of the framework will also be processed as a "usage requirement".
       This has the same effect as passing the framework directory as an
       include directory.  target_link_libraries(<target>

                             <PRIVATE|PUBLIC|INTERFACE> <lib> ...
                             [<PRIVATE|PUBLIC|INTERFACE> <lib> ... ] ...])

       The PUBLIC, PRIVATE and INTERFACE keywords can be used to specify both
       the link dependencies and the link interface in one command.
       Libraries and targets following PUBLIC are linked to, and are made
       part of the link interface.  Libraries and targets following PRIVATE
       are linked to, but are not made part of the link interface.  Libraries
       following INTERFACE are appended to the link interface and are not
       used for linking <target>.

         target_link_libraries(<target> LINK_INTERFACE_LIBRARIES
                               [[debug|optimized|general] <lib>] ...)

       The LINK_INTERFACE_LIBRARIES mode appends the libraries to the
       INTERFACE_LINK_LIBRARIES target property instead of using them for
       linking.  If policy CMP0022 is not NEW, then this mode also appends
       libraries to the LINK_INTERFACE_LIBRARIES and its per-configuration
       equivalent.  This signature is for compatibility only.  Prefer the
       INTERFACE mode instead.  Libraries specified as "debug" are wrapped in
       a generator expression to correspond to debug builds.  If policy
       CMP0022 is not NEW, the libraries are also appended to the
       LINK_INTERFACE_LIBRARIES_DEBUG property (or to the properties
       corresponding to configurations listed in the DEBUG_CONFIGURATIONS
       global property if it is set).  Libraries specified as "optimized" are
       appended to the INTERFACE_LINK_LIBRARIES property.  If policy CMP0022
       is not NEW, they are also appended to the LINK_INTERFACE_LIBRARIES
       property.  Libraries specified as "general" (or without any keyword)
       are treated as if specified for both "debug" and "optimized".

         target_link_libraries(<target>
                               <LINK_PRIVATE|LINK_PUBLIC>
                                 [[debug|optimized|general] <lib>] ...
                               [<LINK_PRIVATE|LINK_PUBLIC>
                                 [[debug|optimized|general] <lib>] ...])

       The LINK_PUBLIC and LINK_PRIVATE modes can be used to specify both the
       link dependencies and the link interface in one command.  This
       signature is for compatibility only.  Prefer the PUBLIC or PRIVATE
       keywords instead.  Libraries and targets following LINK_PUBLIC are
       linked to, and are made part of the INTERFACE_LINK_LIBRARIES.  If
       policy CMP0022 is not NEW, they are also made part of the
       LINK_INTERFACE_LIBRARIES.  Libraries and targets following
       LINK_PRIVATE are linked to, but are not made part of the
       INTERFACE_LINK_LIBRARIES (or LINK_INTERFACE_LIBRARIES).

       The library dependency graph is normally acyclic (a DAG), but in the
       case of mutually-dependent STATIC libraries CMake allows the graph to
       contain cycles (strongly connected components).  When another target
       links to one of the libraries CMake repeats the entire connected
       component.  For example, the code

         add_library(A STATIC a.c)
         add_library(B STATIC b.c)
         target_link_libraries(A B)
         target_link_libraries(B A)
         add_executable(main main.c)
         target_link_libraries(main A)

       links 'main' to 'A B A B'.  (While one repetition is usually
       sufficient, pathological object file and symbol arrangements can
       require more.  One may handle such cases by manually repeating the
       component in the last target_link_libraries call.  However, if two
       archives are really so interdependent they should probably be combined
       into a single archive.)

       Arguments to target_link_libraries may use "generator expressions"
       with the syntax "$<...>".  Note however, that generator expressions
       will not be used in OLD handling of CMP0003 or CMP0004.

       Generator expressions are evaluated during build system generation to
       produce information specific to each build configuration.  Valid
       expressions are:

         $<0:...>                  = empty string (ignores "...")
         $<1:...>                  = content of "..."
         $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
         $<CONFIGURATION>          = configuration name
         $<BOOL:...>               = '1' if the '...' is true, else '0'
         $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
         $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
         $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
         $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
         $<JOIN:list,...>          = joins the list with the content of "..."
         $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
         $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
         $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
         $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
         $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
         $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
         $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
         $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
         $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
         $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
         $<C_COMPILER_VERSION>     = The version of the C compiler used.
         $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
         $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
         $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
         $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
         $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
         $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

       where "tgt" is the name of a target.  Target file expressions produce
       a full path, but _DIR and _NAME versions can produce the directory and
       file name components:

         $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
         $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
         $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

       

         $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

       Note that tgt is not added as a dependency of the target this
       expression is evaluated on.

         $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
         $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

       Boolean expressions:

         $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
         $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
         $<NOT:?>                  = '0' if '?' is '1', else '1'

       where '?' is always either '0' or '1'.

       Expressions with an implicit 'this' target:

         $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.


  try_compile
       Try building some code.

         try_compile(RESULT_VAR <bindir> <srcdir>
                     <projectName> [targetName] [CMAKE_FLAGS flags...]
                     [OUTPUT_VARIABLE <var>])

       Try building a project.  In this form, srcdir should contain a
       complete CMake project with a CMakeLists.txt file and all sources.
       The bindir and srcdir will not be deleted after this command is run.
       Specify targetName to build a specific target instead of the 'all' or
       'ALL_BUILD' target.

         try_compile(RESULT_VAR <bindir> <srcfile|SOURCES srcfile...>
                     [CMAKE_FLAGS flags...]
                     [COMPILE_DEFINITIONS flags...]
                     [LINK_LIBRARIES libs...]
                     [OUTPUT_VARIABLE <var>]
                     [COPY_FILE <fileName> [COPY_FILE_ERROR <var>]])

       Try building an executable from one or more source files.  In this
       form the user need only supply one or more source files that include a
       definition for 'main'.  CMake will create a CMakeLists.txt file to
       build the source(s) as an executable.  Specify COPY_FILE to get a copy
       of the linked executable at the given fileName and optionally
       COPY_FILE_ERROR to capture any error.

       In this version all files in bindir/CMakeFiles/CMakeTmp will be
       cleaned automatically.  For debugging, --debug-trycompile can be
       passed to cmake to avoid this clean.  However, multiple sequential
       try_compile operations reuse this single output directory.  If you use
       --debug-trycompile, you can only debug one try_compile call at a time.
       The recommended procedure is to configure with cmake all the way
       through once, then delete the cache entry associated with the
       try_compile call of interest, and then re-run cmake again with
       --debug-trycompile.

       Some extra flags that can be included are, INCLUDE_DIRECTORIES,
       LINK_DIRECTORIES, and LINK_LIBRARIES.  COMPILE_DEFINITIONS are
       -Ddefinition that will be passed to the compile line.

       The srcfile signature also accepts a LINK_LIBRARIES argument which may
       contain a list of libraries or IMPORTED targets which will be linked
       to in the generated project.  If LINK_LIBRARIES is specified as a
       parameter to try_compile, then any LINK_LIBRARIES passed as
       CMAKE_FLAGS will be ignored.

       try_compile creates a CMakeList.txt file on the fly that looks like
       this:

         add_definitions( <expanded COMPILE_DEFINITIONS from calling cmake>)
         include_directories(${INCLUDE_DIRECTORIES})
         link_directories(${LINK_DIRECTORIES})
         add_executable(cmTryCompileExec sources)
         target_link_libraries(cmTryCompileExec ${LINK_LIBRARIES})

       In both versions of the command, if OUTPUT_VARIABLE is specified, then
       the output from the build process is stored in the given variable.
       The success or failure of the try_compile, i.e.  TRUE or FALSE
       respectively, is returned in RESULT_VAR.  CMAKE_FLAGS can be used to
       pass -DVAR:TYPE=VALUE flags to the cmake that is run during the build.
       Set variable CMAKE_TRY_COMPILE_CONFIGURATION to choose a build
       configuration.

  try_run
       Try compiling and then running some code.

         try_run(RUN_RESULT_VAR COMPILE_RESULT_VAR
                 bindir srcfile [CMAKE_FLAGS <Flags>]
                 [COMPILE_DEFINITIONS <flags>]
                 [COMPILE_OUTPUT_VARIABLE comp]
                 [RUN_OUTPUT_VARIABLE run]
                 [OUTPUT_VARIABLE var]
                 [ARGS <arg1> <arg2>...])

       Try compiling a srcfile.  Return TRUE or FALSE for success or failure
       in COMPILE_RESULT_VAR.  Then if the compile succeeded, run the
       executable and return its exit code in RUN_RESULT_VAR.  If the
       executable was built, but failed to run, then RUN_RESULT_VAR will be
       set to FAILED_TO_RUN.  COMPILE_OUTPUT_VARIABLE specifies the variable
       where the output from the compile step goes.  RUN_OUTPUT_VARIABLE
       specifies the variable where the output from the running executable
       goes.

       For compatibility reasons OUTPUT_VARIABLE is still supported, which
       gives you the output from the compile and run step combined.

       Cross compiling issues

       When cross compiling, the executable compiled in the first step
       usually cannot be run on the build host.  try_run() checks the
       CMAKE_CROSSCOMPILING variable to detect whether CMake is in
       crosscompiling mode.  If that's the case, it will still try to compile
       the executable, but it will not try to run the executable.  Instead it
       will create cache variables which must be filled by the user or by
       presetting them in some CMake script file to the values the executable
       would have produced if it had been run on its actual target platform.
       These variables are RUN_RESULT_VAR (explanation see above) and if
       RUN_OUTPUT_VARIABLE (or OUTPUT_VARIABLE) was used, an additional cache
       variable RUN_RESULT_VAR__COMPILE_RESULT_VAR__TRYRUN_OUTPUT.This is
       intended to hold stdout and stderr from the executable.

       In order to make cross compiling your project easier, use try_run only
       if really required.  If you use try_run, use RUN_OUTPUT_VARIABLE (or
       OUTPUT_VARIABLE) only if really required.  Using them will require
       that when crosscompiling, the cache variables will have to be set
       manually to the output of the executable.  You can also "guard" the
       calls to try_run with if(CMAKE_CROSSCOMPILING) and provide an
       easy-to-preset alternative for this case.

       Set variable CMAKE_TRY_COMPILE_CONFIGURATION to choose a build
       configuration.

  unset
       Unset a variable, cache variable, or environment variable.

         unset(<variable> [CACHE])

       Removes the specified variable causing it to become undefined.  If
       CACHE is present then the variable is removed from the cache instead
       of the current scope.

       <variable> can be an environment variable such as:

         unset(ENV{LD_LIBRARY_PATH})

       in which case the variable will be removed from the current
       environment.

  variable_watch
       Watch the CMake variable for change.

         variable_watch(<variable name> [<command to execute>])

       If the specified variable changes, the message will be printed about
       the variable being changed.  If the command is specified, the command
       will be executed.  The command will receive the following arguments:
       COMMAND(<variable> <access> <value> <current list file> <stack>)

  while
       Evaluate a group of commands while a condition is true

         while(condition)
           COMMAND1(ARGS ...)
           COMMAND2(ARGS ...)
           ...
         endwhile(condition)

       All commands between while and the matching endwhile are recorded
       without being invoked.  Once the endwhile is evaluated, the recorded
       list of commands is invoked as long as the condition is true.  The
       condition is evaluated using the same logic as the if command.

------------------------------------------------------------------------------
Properties

  CMake Properties - Properties supported by CMake, the Cross-Platform Makefile Generator.

This is the documentation for the properties supported by CMake.  Properties
can have different scopes.  They can either be assigned to a source file, a
directory, a target or globally to CMake.  By modifying the values of
properties the behaviour of the build system can be customized.

------------------------------------------------------------------------------
Properties of Global Scope

  ALLOW_DUPLICATE_CUSTOM_TARGETS
       Allow duplicate custom targets to be created.

       Normally CMake requires that all targets built in a project have
       globally unique logical names (see policy CMP0002).  This is necessary
       to generate meaningful project file names in Xcode and VS IDE
       generators.  It also allows the target names to be referenced
       unambiguously.

       Makefile generators are capable of supporting duplicate custom target
       names.  For projects that care only about Makefile generators and do
       not wish to support Xcode or VS IDE generators, one may set this
       property to true to allow duplicate custom targets.  The property
       allows multiple add_custom_target command calls in different
       directories to specify the same target name.  However, setting this
       property will cause non-Makefile generators to produce an error and
       refuse to generate the project.

  AUTOMOC_TARGETS_FOLDER
       Name of FOLDER for *_automoc targets that are added automatically by
       CMake for targets for which AUTOMOC is enabled.

       If not set, CMake uses the FOLDER property of the parent target as a
       default value for this property.  See also the documentation for the
       FOLDER target property and the AUTOMOC target property.

  DEBUG_CONFIGURATIONS
       Specify which configurations are for debugging.

       The value must be a semi-colon separated list of configuration names.
       Currently this property is used only by the target_link_libraries
       command (see its documentation for details).  Additional uses may be
       defined in the future.

       This property must be set at the top level of the project and before
       the first target_link_libraries command invocation.  If any entry in
       the list does not match a valid configuration for the project the
       behavior is undefined.

  DISABLED_FEATURES
       List of features which are disabled during the CMake run.

       List of features which are disabled during the CMake run.  By default
       it contains the names of all packages which were not found.  This is
       determined using the <NAME>_FOUND variables.  Packages which are
       searched QUIET are not listed.  A project can add its own features to
       this list.  This property is used by the macros in
       FeatureSummary.cmake.

  ENABLED_FEATURES
       List of features which are enabled during the CMake run.

       List of features which are enabled during the CMake run.  By default
       it contains the names of all packages which were found.  This is
       determined using the <NAME>_FOUND variables.  Packages which are
       searched QUIET are not listed.  A project can add its own features to
       this list.  This property is used by the macros in
       FeatureSummary.cmake.

  ENABLED_LANGUAGES
       Read-only property that contains the list of currently enabled
       languages

       Set to list of currently enabled languages.

  FIND_LIBRARY_USE_LIB64_PATHS
       Whether FIND_LIBRARY should automatically search lib64 directories.

       FIND_LIBRARY_USE_LIB64_PATHS is a boolean specifying whether the
       FIND_LIBRARY command should automatically search the lib64 variant of
       directories called lib in the search path when building 64-bit
       binaries.

  FIND_LIBRARY_USE_OPENBSD_VERSIONING
       Whether FIND_LIBRARY should find OpenBSD-style shared libraries.

       This property is a boolean specifying whether the FIND_LIBRARY command
       should find shared libraries with OpenBSD-style versioned extension:
       ".so.<major>.<minor>".  The property is set to true on OpenBSD and
       false on other platforms.

  GLOBAL_DEPENDS_DEBUG_MODE
       Enable global target dependency graph debug mode.

       CMake automatically analyzes the global inter-target dependency graph
       at the beginning of native build system generation.  This property
       causes it to display details of its analysis to stderr.

  GLOBAL_DEPENDS_NO_CYCLES
       Disallow global target dependency graph cycles.

       CMake automatically analyzes the global inter-target dependency graph
       at the beginning of native build system generation.  It reports an
       error if the dependency graph contains a cycle that does not consist
       of all STATIC library targets.  This property tells CMake to disallow
       all cycles completely, even among static libraries.

  IN_TRY_COMPILE
       Read-only property that is true during a try-compile configuration.

       True when building a project inside a TRY_COMPILE or TRY_RUN command.

  PACKAGES_FOUND
       List of packages which were found during the CMake run.

       List of packages which were found during the CMake run.  Whether a
       package has been found is determined using the <NAME>_FOUND variables.

  PACKAGES_NOT_FOUND
       List of packages which were not found during the CMake run.

       List of packages which were not found during the CMake run.  Whether a
       package has been found is determined using the <NAME>_FOUND variables.

  PREDEFINED_TARGETS_FOLDER
       Name of FOLDER for targets that are added automatically by CMake.

       If not set, CMake uses "CMakePredefinedTargets" as a default value for
       this property.  Targets such as INSTALL, PACKAGE and RUN_TESTS will be
       organized into this FOLDER.  See also the documentation for the FOLDER
       target property.

  REPORT_UNDEFINED_PROPERTIES
       If set, report any undefined properties to this file.

       If this property is set to a filename then when CMake runs it will
       report any properties or variables that were accessed but not defined
       into the filename specified in this property.

  RULE_LAUNCH_COMPILE
       Specify a launcher for compile rules.

       Makefile generators prefix compiler commands with the given launcher
       command line.  This is intended to allow launchers to intercept build
       problems with high granularity.  Non-Makefile generators currently
       ignore this property.

  RULE_LAUNCH_CUSTOM
       Specify a launcher for custom rules.

       Makefile generators prefix custom commands with the given launcher
       command line.  This is intended to allow launchers to intercept build
       problems with high granularity.  Non-Makefile generators currently
       ignore this property.

  RULE_LAUNCH_LINK
       Specify a launcher for link rules.

       Makefile generators prefix link and archive commands with the given
       launcher command line.  This is intended to allow launchers to
       intercept build problems with high granularity.  Non-Makefile
       generators currently ignore this property.

  RULE_MESSAGES
       Specify whether to report a message for each make rule.

       This property specifies whether Makefile generators should add a
       progress message describing what each build rule does.  If the
       property is not set the default is ON.  Set the property to OFF to
       disable granular messages and report only as each target completes.
       This is intended to allow scripted builds to avoid the build time cost
       of detailed reports.  If a CMAKE_RULE_MESSAGES cache entry exists its
       value initializes the value of this property.  Non-Makefile generators
       currently ignore this property.

  TARGET_ARCHIVES_MAY_BE_SHARED_LIBS
       Set if shared libraries may be named like archives.

       On AIX shared libraries may be named "lib<name>.a".  This property is
       set to true on such platforms.

  TARGET_SUPPORTS_SHARED_LIBS
       Does the target platform support shared libraries.

       TARGET_SUPPORTS_SHARED_LIBS is a boolean specifying whether the target
       platform supports shared libraries.  Basically all current general
       general purpose OS do so, the exception are usually embedded systems
       with no or special OSs.

  USE_FOLDERS
       Use the FOLDER target property to organize targets into folders.

       If not set, CMake treats this property as OFF by default.  CMake
       generators that are capable of organizing into a hierarchy of folders
       use the values of the FOLDER target property to name those folders.
       See also the documentation for the FOLDER target property.

  __CMAKE_DELETE_CACHE_CHANGE_VARS_
       Internal property

       Used to detect compiler changes, Do not set.

------------------------------------------------------------------------------
Properties on Directories

  ADDITIONAL_MAKE_CLEAN_FILES
       Additional files to clean during the make clean stage.

       A list of files that will be cleaned as a part of the "make clean"
       stage.

  CACHE_VARIABLES
       List of cache variables available in the current directory.

       This read-only property specifies the list of CMake cache variables
       currently defined.  It is intended for debugging purposes.

  CLEAN_NO_CUSTOM
       Should the output of custom commands be left.

       If this is true then the outputs of custom commands for this directory
       will not be removed during the "make clean" stage.

  COMPILE_DEFINITIONS
       Preprocessor definitions for compiling a directory's sources.

       The COMPILE_DEFINITIONS property may be set to a semicolon-separated
       list of preprocessor definitions using the syntax VAR or VAR=value.
       Function-style definitions are not supported.  CMake will
       automatically escape the value correctly for the native build system
       (note that CMake language syntax may require escapes to specify some
       values).  This property may be set on a per-configuration basis using
       the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case
       name (ex.  "COMPILE_DEFINITIONS_DEBUG").  This property will be
       initialized in each directory by its value in the directory's parent.

       CMake will automatically drop some definitions that are not supported
       by the native build tool.  The VS6 IDE does not support definition
       values with spaces (but NMake does).

       Disclaimer: Most native build tools have poor support for escaping
       certain values.  CMake has work-arounds for many cases but some values
       may just not be possible to pass correctly.  If a value does not seem
       to be escaped correctly, do not attempt to work-around the problem by
       adding escape sequences to the value.  Your work-around may break in a
       future version of CMake that has improved escape support.  Instead
       consider defining the macro in a (configured) header file.  Then
       report the limitation.  Known limitations include:

         #          - broken almost everywhere
         ;          - broken in VS IDE 7.0 and Borland Makefiles
         ,          - broken in VS IDE
         %          - broken in some cases in NMake
         & |        - broken in some cases on MinGW
         ^ < > \"   - broken in most Make tools on Windows

       CMake does not reject these values outright because they do work in
       some cases.  Use with caution.

  COMPILE_DEFINITIONS_<CONFIG>
       Per-configuration preprocessor definitions in a directory.

       This is the configuration-specific version of COMPILE_DEFINITIONS.
       This property will be initialized in each directory by its value in
       the directory's parent.


  COMPILE_OPTIONS
       List of options to pass to the compiler.

       This property specifies the list of directories given so far for this
       property.  This property exists on directories and targets.

       The target property values are used by the generators to set the
       options for the compiler.

       Contents of COMPILE_OPTIONS may use "generator expressions" with the
       syntax "$<...>".  Generator expressions are evaluated during build
       system generation to produce information specific to each build
       configuration.  Valid expressions are:

         $<0:...>                  = empty string (ignores "...")
         $<1:...>                  = content of "..."
         $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
         $<CONFIGURATION>          = configuration name
         $<BOOL:...>               = '1' if the '...' is true, else '0'
         $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
         $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
         $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
         $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
         $<JOIN:list,...>          = joins the list with the content of "..."
         $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
         $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
         $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
         $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
         $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
         $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
         $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
         $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
         $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
         $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
         $<C_COMPILER_VERSION>     = The version of the C compiler used.
         $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
         $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
         $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
         $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
         $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
         $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

       where "tgt" is the name of a target.  Target file expressions produce
       a full path, but _DIR and _NAME versions can produce the directory and
       file name components:

         $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
         $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
         $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

       

         $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

       Note that tgt is not added as a dependency of the target this
       expression is evaluated on.

         $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
         $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

       Boolean expressions:

         $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
         $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
         $<NOT:?>                  = '0' if '?' is '1', else '1'

       where '?' is always either '0' or '1'.

       Expressions with an implicit 'this' target:

         $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.


  DEFINITIONS
       For CMake 2.4 compatibility only.  Use COMPILE_DEFINITIONS instead.

       This read-only property specifies the list of flags given so far to
       the add_definitions command.  It is intended for debugging purposes.
       Use the COMPILE_DEFINITIONS instead.

  EXCLUDE_FROM_ALL
       Exclude the directory from the all target of its parent.

       A property on a directory that indicates if its targets are excluded
       from the default build target.  If it is not, then with a Makefile for
       example typing make will cause the targets to be built.  The same
       concept applies to the default build of other generators.

  IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
       Specify #include line transforms for dependencies in a directory.

       This property specifies rules to transform macro-like #include lines
       during implicit dependency scanning of C and C++ source files.  The
       list of rules must be semicolon-separated with each entry of the form
       "A_MACRO(%)=value-with-%" (the % must be literal).  During dependency
       scanning occurrences of A_MACRO(...) on #include lines will be
       replaced by the value given with the macro argument substituted for
       '%'.  For example, the entry

         MYDIR(%)=<mydir/%>

       will convert lines of the form

         #include MYDIR(myheader.h)

       to

         #include <mydir/myheader.h>

       allowing the dependency to be followed.

       This property applies to sources in all targets within a directory.
       The property value is initialized in each directory by its value in
       the directory's parent.

  INCLUDE_DIRECTORIES
       List of preprocessor include file search directories.

       This property specifies the list of directories given so far to the
       include_directories command.  This property exists on directories and
       targets.  In addition to accepting values from the include_directories
       command, values may be set directly on any directory or any target
       using the set_property command.  A target gets its initial value for
       this property from the value of the directory property.  A directory
       gets its initial value from its parent directory if it has one.  Both
       directory and target property values are adjusted by calls to the
       include_directories command.

       The target property values are used by the generators to set the
       include paths for the compiler.  See also the include_directories
       command.

  INCLUDE_REGULAR_EXPRESSION
       Include file scanning regular expression.

       This read-only property specifies the regular expression used during
       dependency scanning to match include files that should be followed.
       See the include_regular_expression command.

  INTERPROCEDURAL_OPTIMIZATION
       Enable interprocedural optimization for targets in a directory.

       If set to true, enables interprocedural optimizations if they are
       known to be supported by the compiler.

  INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
       Per-configuration interprocedural optimization for a directory.

       This is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION.
       If set, this property overrides the generic property for the named
       configuration.

  LINK_DIRECTORIES
       List of linker search directories.

       This read-only property specifies the list of directories given so far
       to the link_directories command.  It is intended for debugging
       purposes.

  LISTFILE_STACK
       The current stack of listfiles being processed.

       This property is mainly useful when trying to debug errors in your
       CMake scripts.  It returns a list of what list files are currently
       being processed, in order.  So if one listfile does an INCLUDE command
       then that is effectively pushing the included listfile onto the stack.

  MACROS
       List of macro commands available in the current directory.

       This read-only property specifies the list of CMake macros currently
       defined.  It is intended for debugging purposes.  See the macro
       command.

  PARENT_DIRECTORY
       Source directory that added current subdirectory.

       This read-only property specifies the source directory that added the
       current source directory as a subdirectory of the build.  In the
       top-level directory the value is the empty-string.

  RULE_LAUNCH_COMPILE
       Specify a launcher for compile rules.

       See the global property of the same name for details.  This overrides
       the global property for a directory.

  RULE_LAUNCH_CUSTOM
       Specify a launcher for custom rules.

       See the global property of the same name for details.  This overrides
       the global property for a directory.

  RULE_LAUNCH_LINK
       Specify a launcher for link rules.

       See the global property of the same name for details.  This overrides
       the global property for a directory.

  TEST_INCLUDE_FILE
       A cmake file that will be included when ctest is run.

       If you specify TEST_INCLUDE_FILE, that file will be included and
       processed when ctest is run on the directory.

  VARIABLES
       List of variables defined in the current directory.

       This read-only property specifies the list of CMake variables
       currently defined.  It is intended for debugging purposes.

  VS_GLOBAL_SECTION_POST_<section>
       Specify a postSolution global section in Visual Studio.

       Setting a property like this generates an entry of the following form
       in the solution file:

         GlobalSection(<section>) = postSolution
           <contents based on property value>
         EndGlobalSection

       The property must be set to a semicolon-separated list of key=value
       pairs.  Each such pair will be transformed into an entry in the
       solution global section.  Whitespace around key and value is ignored.
       List elements which do not contain an equal sign are skipped.

       This property only works for Visual Studio 7 and above; it is ignored
       on other generators.  The property only applies when set on a
       directory whose CMakeLists.txt contains a project() command.

       Note that CMake generates postSolution sections ExtensibilityGlobals
       and ExtensibilityAddIns by default.  If you set the corresponding
       property, it will override the default section.  For example, setting
       VS_GLOBAL_SECTION_POST_ExtensibilityGlobals will override the default
       contents of the ExtensibilityGlobals section, while keeping
       ExtensibilityAddIns on its default.

  VS_GLOBAL_SECTION_PRE_<section>
       Specify a preSolution global section in Visual Studio.

       Setting a property like this generates an entry of the following form
       in the solution file:

         GlobalSection(<section>) = preSolution
           <contents based on property value>
         EndGlobalSection

       The property must be set to a semicolon-separated list of key=value
       pairs.  Each such pair will be transformed into an entry in the
       solution global section.  Whitespace around key and value is ignored.
       List elements which do not contain an equal sign are skipped.

       This property only works for Visual Studio 7 and above; it is ignored
       on other generators.  The property only applies when set on a
       directory whose CMakeLists.txt contains a project() command.

------------------------------------------------------------------------------
Properties on Targets

  <CONFIG>_OUTPUT_NAME
       Old per-configuration target file base name.

       This is a configuration-specific version of OUTPUT_NAME.  Use
       OUTPUT_NAME_<CONFIG> instead.

  <CONFIG>_POSTFIX
       Postfix to append to the target file name for configuration <CONFIG>.

       When building with configuration <CONFIG> the value of this property
       is appended to the target file name built on disk.  For non-executable
       targets, this property is initialized by the value of the variable
       CMAKE_<CONFIG>_POSTFIX if it is set when a target is created.  This
       property is ignored on the Mac for Frameworks and App Bundles.

  <LANG>_VISIBILITY_PRESET
       Value for symbol visibility compile flags

       The <LANG>_VISIBILITY_PRESET property determines the value passed in a
       visibility related compile option, such as -fvisibility= for <LANG>.
       This property only has an affect for libraries and executables with
       exports.  This property is initialized by the value of the variable
       CMAKE_<LANG>_VISIBILITY_PRESET if it is set when a target is created.

  ALIASED_TARGET
       Name of target aliased by this target.

       If this is an ALIAS target, this property contains the name of the
       target aliased.

  ARCHIVE_OUTPUT_DIRECTORY
       Output directory in which to build ARCHIVE target files.

       This property specifies the directory into which archive target files
       should be built.  Multi-configuration generators (VS, Xcode) append a
       per-configuration subdirectory to the specified directory.  There are
       three kinds of target files that may be built: archive, library, and
       runtime.  Executables are always treated as runtime targets.  Static
       libraries are always treated as archive targets.  Module libraries are
       always treated as library targets.  For non-DLL platforms shared
       libraries are treated as library targets.  For DLL platforms the DLL
       part of a shared library is treated as a runtime target and the
       corresponding import library is treated as an archive target.  All
       Windows-based systems including Cygwin are DLL platforms.  This
       property is initialized by the value of the variable
       CMAKE_ARCHIVE_OUTPUT_DIRECTORY if it is set when a target is created.

  ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>
       Per-configuration output directory for ARCHIVE target files.

       This is a per-configuration version of ARCHIVE_OUTPUT_DIRECTORY, but
       multi-configuration generators (VS, Xcode) do NOT append a
       per-configuration subdirectory to the specified directory.  This
       property is initialized by the value of the variable
       CMAKE_ARCHIVE_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
       created.

  ARCHIVE_OUTPUT_NAME
       Output name for ARCHIVE target files.

       This property specifies the base name for archive target files.  It
       overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  There are
       three kinds of target files that may be built: archive, library, and
       runtime.  Executables are always treated as runtime targets.  Static
       libraries are always treated as archive targets.  Module libraries are
       always treated as library targets.  For non-DLL platforms shared
       libraries are treated as library targets.  For DLL platforms the DLL
       part of a shared library is treated as a runtime target and the
       corresponding import library is treated as an archive target.  All
       Windows-based systems including Cygwin are DLL platforms.

  ARCHIVE_OUTPUT_NAME_<CONFIG>
       Per-configuration output name for ARCHIVE target files.

       This is the configuration-specific version of ARCHIVE_OUTPUT_NAME.

  AUTOMOC
       Should the target be processed with automoc (for Qt projects).

       AUTOMOC is a boolean specifying whether CMake will handle the Qt moc
       preprocessor automatically, i.e.  without having to use the
       QT4_WRAP_CPP() or QT5_WRAP_CPP() macro.  Currently Qt4 and Qt5 are
       supported.  When this property is set to TRUE, CMake will scan the
       source files at build time and invoke moc accordingly.  If an #include
       statement like #include "moc_foo.cpp" is found, the Q_OBJECT class
       declaration is expected in the header, and moc is run on the header
       file.  If an #include statement like #include "foo.moc" is found, then
       a Q_OBJECT is expected in the current source file and moc is run on
       the file itself.  Additionally, all header files are parsed for
       Q_OBJECT macros, and if found, moc is also executed on those files.
       The resulting moc files, which are not included as shown above in any
       of the source files are included in a generated
       <targetname>_automoc.cpp file, which is compiled as part of the
       target.This property is initialized by the value of the variable
       CMAKE_AUTOMOC if it is set when a target is created.

       Additional command line options for moc can be set via the
       AUTOMOC_MOC_OPTIONS property.

       By setting the CMAKE_AUTOMOC_RELAXED_MODE variable to TRUE the rules
       for searching the files which will be processed by moc can be relaxed.
       See the documentation for this variable for more details.

       The global property AUTOMOC_TARGETS_FOLDER can be used to group the
       automoc targets together in an IDE, e.g.  in MSVS.

  AUTOMOC_MOC_OPTIONS
       Additional options for moc when using automoc (see the AUTOMOC
       property)

       This property is only used if the AUTOMOC property is set to TRUE for
       this target.  In this case, it holds additional command line options
       which will be used when moc is executed during the build, i.e.  it is
       equivalent to the optional OPTIONS argument of the qt4_wrap_cpp()
       macro.

       By default it is empty.

  BUILD_WITH_INSTALL_RPATH
       Should build tree targets have install tree rpaths.

       BUILD_WITH_INSTALL_RPATH is a boolean specifying whether to link the
       target in the build tree with the INSTALL_RPATH.  This takes
       precedence over SKIP_BUILD_RPATH and avoids the need for relinking
       before installation.  This property is initialized by the value of the
       variable CMAKE_BUILD_WITH_INSTALL_RPATH if it is set when a target is
       created.

  BUNDLE
       This target is a CFBundle on the Mac.

       If a module library target has this property set to true it will be
       built as a CFBundle when built on the mac.  It will have the directory
       structure required for a CFBundle and will be suitable to be used for
       creating Browser Plugins or other application resources.

  BUNDLE_EXTENSION
       The file extension used to name a BUNDLE target on the Mac.

       The default value is "bundle" - you can also use "plugin" or whatever
       file extension is required by the host app for your bundle.

  COMPATIBLE_INTERFACE_BOOL
       Properties which must be compatible with their link interface

       The COMPATIBLE_INTERFACE_BOOL property may contain a list of
       propertiesfor this target which must be consistent when evaluated as a
       boolean in the INTERFACE of all linked dependees.  For example, if a
       property "FOO" appears in the list, then for each dependee, the
       "INTERFACE_FOO" property content in all of its dependencies must be
       consistent with each other, and with the "FOO" property in the
       dependee.  Consistency in this sense has the meaning that if the
       property is set, then it must have the same boolean value as all
       others, and if the property is not set, then it is ignored.  Note that
       for each dependee, the set of properties from this property must not
       intersect with the set of properties from the
       COMPATIBLE_INTERFACE_STRING property.

  COMPATIBLE_INTERFACE_STRING
       Properties which must be string-compatible with their link interface

       The COMPATIBLE_INTERFACE_STRING property may contain a list of
       properties for this target which must be the same when evaluated as a
       string in the INTERFACE of all linked dependees.  For example, if a
       property "FOO" appears in the list, then for each dependee, the
       "INTERFACE_FOO" property content in all of its dependencies must be
       equal with each other, and with the "FOO" property in the dependee.
       If the property is not set, then it is ignored.  Note that for each
       dependee, the set of properties from this property must not intersect
       with the set of properties from the COMPATIBLE_INTERFACE_BOOL
       property.

  COMPILE_DEFINITIONS
       Preprocessor definitions for compiling a target's sources.

       The COMPILE_DEFINITIONS property may be set to a semicolon-separated
       list of preprocessor definitions using the syntax VAR or VAR=value.
       Function-style definitions are not supported.  CMake will
       automatically escape the value correctly for the native build system
       (note that CMake language syntax may require escapes to specify some
       values).  This property may be set on a per-configuration basis using
       the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case
       name (ex.  "COMPILE_DEFINITIONS_DEBUG").

       CMake will automatically drop some definitions that are not supported
       by the native build tool.  The VS6 IDE does not support definition
       values with spaces (but NMake does).

       Contents of COMPILE_DEFINITIONS may use "generator expressions" with
       the syntax "$<...>".  Generator expressions are evaluated during build
       system generation to produce information specific to each build
       configuration.  Valid expressions are:

         $<0:...>                  = empty string (ignores "...")
         $<1:...>                  = content of "..."
         $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
         $<CONFIGURATION>          = configuration name
         $<BOOL:...>               = '1' if the '...' is true, else '0'
         $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
         $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
         $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
         $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
         $<JOIN:list,...>          = joins the list with the content of "..."
         $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
         $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
         $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
         $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
         $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
         $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
         $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
         $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
         $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
         $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
         $<C_COMPILER_VERSION>     = The version of the C compiler used.
         $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
         $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
         $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
         $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
         $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
         $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

       where "tgt" is the name of a target.  Target file expressions produce
       a full path, but _DIR and _NAME versions can produce the directory and
       file name components:

         $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
         $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
         $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

       

         $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

       Note that tgt is not added as a dependency of the target this
       expression is evaluated on.

         $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
         $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

       Boolean expressions:

         $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
         $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
         $<NOT:?>                  = '0' if '?' is '1', else '1'

       where '?' is always either '0' or '1'.

       Expressions with an implicit 'this' target:

         $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.

       Disclaimer: Most native build tools have poor support for escaping
       certain values.  CMake has work-arounds for many cases but some values
       may just not be possible to pass correctly.  If a value does not seem
       to be escaped correctly, do not attempt to work-around the problem by
       adding escape sequences to the value.  Your work-around may break in a
       future version of CMake that has improved escape support.  Instead
       consider defining the macro in a (configured) header file.  Then
       report the limitation.  Known limitations include:

         #          - broken almost everywhere
         ;          - broken in VS IDE 7.0 and Borland Makefiles
         ,          - broken in VS IDE
         %          - broken in some cases in NMake
         & |        - broken in some cases on MinGW
         ^ < > \"   - broken in most Make tools on Windows

       CMake does not reject these values outright because they do work in
       some cases.  Use with caution.

  COMPILE_DEFINITIONS_<CONFIG>
       Per-configuration preprocessor definitions on a target.

       This is the configuration-specific version of COMPILE_DEFINITIONS.

  COMPILE_FLAGS
       Additional flags to use when compiling this target's sources.

       The COMPILE_FLAGS property sets additional compiler flags used to
       build sources within the target.  Use COMPILE_DEFINITIONS to pass
       additional preprocessor definitions.

  COMPILE_OPTIONS
       List of options to pass to the compiler.

       This property specifies the list of options specified so far for this
       property.  This property exists on directories and targets.

       The target property values are used by the generators to set the
       options for the compiler.

       Contents of COMPILE_OPTIONS may use "generator expressions" with the
       syntax "$<...>".  Generator expressions are evaluated during build
       system generation to produce information specific to each build
       configuration.  Valid expressions are:

         $<0:...>                  = empty string (ignores "...")
         $<1:...>                  = content of "..."
         $<CONFIG:cfg>             = '1' if config is "cfg", else '0'
         $<CONFIGURATION>          = configuration name
         $<BOOL:...>               = '1' if the '...' is true, else '0'
         $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
         $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
         $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
         $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
         $<JOIN:list,...>          = joins the list with the content of "..."
         $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
         $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
         $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.
         $<C_COMPILER_ID>          = The CMake-id of the C compiler used.
         $<C_COMPILER_ID:comp>     = '1' if the CMake-id of the C compiler matches comp, otherwise '0'.
         $<CXX_COMPILER_ID>        = The CMake-id of the CXX compiler used.
         $<CXX_COMPILER_ID:comp>   = '1' if the CMake-id of the CXX compiler matches comp, otherwise '0'.
         $<VERSION_GREATER:v1,v2>  = '1' if v1 is a version greater than v2, else '0'.
         $<VERSION_LESS:v1,v2>     = '1' if v1 is a version less than v2, else '0'.
         $<VERSION_EQUAL:v1,v2>    = '1' if v1 is the same version as v2, else '0'.
         $<C_COMPILER_VERSION>     = The version of the C compiler used.
         $<C_COMPILER_VERSION:ver> = '1' if the version of the C compiler matches ver, otherwise '0'.
         $<CXX_COMPILER_VERSION>   = The version of the CXX compiler used.
         $<CXX_COMPILER_VERSION:ver> = '1' if the version of the CXX compiler matches ver, otherwise '0'.
         $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
         $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
         $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

       where "tgt" is the name of a target.  Target file expressions produce
       a full path, but _DIR and _NAME versions can produce the directory and
       file name components:

         $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
         $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
         $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

       

         $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

       Note that tgt is not added as a dependency of the target this
       expression is evaluated on.

         $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
         $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

       Boolean expressions:

         $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
         $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
         $<NOT:?>                  = '0' if '?' is '1', else '1'

       where '?' is always either '0' or '1'.

       Expressions with an implicit 'this' target:

         $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.


  DEBUG_POSTFIX
       See target property <CONFIG>_POSTFIX.

       This property is a special case of the more-general <CONFIG>_POSTFIX
       property for the DEBUG configuration.

  DEFINE_SYMBOL
       Define a symbol when compiling this target's sources.

       DEFINE_SYMBOL sets the name of the preprocessor symbol defined when
       compiling sources in a shared library.  If not set here then it is set
       to target_EXPORTS by default (with some substitutions if the target is
       not a valid C identifier).  This is useful for headers to know whether
       they are being included from inside their library or outside to
       properly setup dllexport/dllimport decorations.

  ENABLE_EXPORTS
       Specify whether an executable exports symbols for loadable modules.

       Normally an executable does not export any symbols because it is the
       final program.  It is possible for an executable to export symbols to
       be used by loadable modules.  When this property is set to true CMake
       will allow other targets to "link" to the executable with the
       TARGET_LINK_LIBRARIES command.  On all platforms a target-level
       dependency on the executable is created for targets that link to it.
       For DLL platforms an import library will be created for the exported
       symbols and then used for linking.  All Windows-based systems
       including Cygwin are DLL platforms.  For non-DLL platforms that
       require all symbols to be resolved at link time, such as Mac OS X, the
       module will "link" to the executable using a flag like
       "-bundle_loader".  For other non-DLL platforms the link rule is simply
       ignored since the dynamic loader will automatically bind symbols when
       the module is loaded.

  EXCLUDE_FROM_ALL
       Exclude the target from the all target.

       A property on a target that indicates if the target is excluded from
       the default build target.  If it is not, then with a Makefile for
       example typing make will cause this target to be built.  The same
       concept applies to the default build of other generators.  Installing
       a target with EXCLUDE_FROM_ALL set to true has undefined behavior.

  EXCLUDE_FROM_DEFAULT_BUILD
       Exclude target from "Build Solution".

       This property is only used by Visual Studio generators 7 and above.
       When set to TRUE, the target will not be built when you press "Build
       Solution".

  EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG>
       Per-configuration version of target exclusion from "Build Solution".

       This is the configuration-specific version of
       EXCLUDE_FROM_DEFAULT_BUILD.  If the generic EXCLUDE_FROM_DEFAULT_BUILD
       is also set on a target, EXCLUDE_FROM_DEFAULT_BUILD_<CONFIG> takes
       precedence in configurations for which it has a value.

  EXPORT_NAME
       Exported name for target files.

       This sets the name for the IMPORTED target generated when it this
       target is is exported.  If not set, the logical target name is used by
       default.

  EchoString
       A message to be displayed when the target is built.

       A message to display on some generators (such as makefiles) when the
       target is built.

  FOLDER
       Set the folder name.  Use to organize targets in an IDE.

       Targets with no FOLDER property will appear as top level entities in
       IDEs like Visual Studio.  Targets with the same FOLDER property value
       will appear next to each other in a folder of that name.  To nest
       folders, use FOLDER values such as 'GUI/Dialogs' with '/' characters
       separating folder levels.

  FRAMEWORK
       This target is a framework on the Mac.

       If a shared library target has this property set to true it will be
       built as a framework when built on the mac.  It will have the
       directory structure required for a framework and will be suitable to
       be used with the -framework option

  Fortran_FORMAT
       Set to FIXED or FREE to indicate the Fortran source layout.

       This property tells CMake whether the Fortran source files in a target
       use fixed-format or free-format.  CMake will pass the corresponding
       format flag to the compiler.  Use the source-specific Fortran_FORMAT
       property to change the format of a specific source file.  If the
       variable CMAKE_Fortran_FORMAT is set when a target is created its
       value is used to initialize this property.

  Fortran_MODULE_DIRECTORY
       Specify output directory for Fortran modules provided by the target.

       If the target contains Fortran source files that provide modules and
       the compiler supports a module output directory this specifies the
       directory in which the modules will be placed.  When this property is
       not set the modules will be placed in the build directory
       corresponding to the target's source directory.  If the variable
       CMAKE_Fortran_MODULE_DIRECTORY is set when a target is created its
       value is used to initialize this property.

       Note that some compilers will automatically search the module output
       directory for modules USEd during compilation but others will not.  If
       your sources USE modules their location must be specified by
       INCLUDE_DIRECTORIES regardless of this property.

  GENERATOR_FILE_NAME
       Generator's file for this target.

       An internal property used by some generators to record the name of the
       project or dsp file associated with this target.  Note that at
       configure time, this property is only set for targets created by
       include_external_msproject().

  GNUtoMS
       Convert GNU import library (.dll.a) to MS format (.lib).

       When linking a shared library or executable that exports symbols using
       GNU tools on Windows (MinGW/MSYS) with Visual Studio installed convert
       the import library (.dll.a) from GNU to MS format (.lib).  Both import
       libraries will be installed by install(TARGETS) and exported by
       install(EXPORT) and export() to be linked by applications with either
       GNU- or MS-compatible tools.

       If the variable CMAKE_GNUtoMS is set when a target is created its
       value is used to initialize this property.  The variable must be set
       prior to the first command that enables a language such as project()
       or enable_language().  CMake provides the variable as an option to the
       user automatically when configuring on Windows with GNU tools.

  HAS_CXX
       Link the target using the C++ linker tool (obsolete).

       This is equivalent to setting the LINKER_LANGUAGE property to CXX.
       See that property's documentation for details.

  IMPLICIT_DEPENDS_INCLUDE_TRANSFORM
       Specify #include line transforms for dependencies in a target.

       This property specifies rules to transform macro-like #include lines
       during implicit dependency scanning of C and C++ source files.  The
       list of rules must be semicolon-separated with each entry of the form
       "A_MACRO(%)=value-with-%" (the % must be literal).  During dependency
       scanning occurrences of A_MACRO(...) on #include lines will be
       replaced by the value given with the macro argument substituted for
       '%'.  For example, the entry

         MYDIR(%)=<mydir/%>

       will convert lines of the form

         #include MYDIR(myheader.h)

       to

         #include <mydir/myheader.h>

       allowing the dependency to be followed.

       This property applies to sources in the target on which it is set.

  IMPORTED
       Read-only indication of whether a target is IMPORTED.

       The boolean value of this property is true for targets created with
       the IMPORTED option to add_executable or add_library.  It is false for
       targets built within the project.

  IMPORTED_CONFIGURATIONS
       Configurations provided for an IMPORTED target.

       Set this to the list of configuration names available for an IMPORTED
       target.  The names correspond to configurations defined in the project
       from which the target is imported.  If the importing project uses a
       different set of configurations the names may be mapped using the
       MAP_IMPORTED_CONFIG_<CONFIG> property.  Ignored for non-imported
       targets.

  IMPORTED_IMPLIB
       Full path to the import library for an IMPORTED target.

       Set this to the location of the ".lib" part of a windows DLL.  Ignored
       for non-imported targets.

  IMPORTED_IMPLIB_<CONFIG>
       <CONFIG>-specific version of IMPORTED_IMPLIB property.

       Configuration names correspond to those provided by the project from
       which the target is imported.

  IMPORTED_LINK_DEPENDENT_LIBRARIES
       Dependent shared libraries of an imported shared library.

       Shared libraries may be linked to other shared libraries as part of
       their implementation.  On some platforms the linker searches for the
       dependent libraries of shared libraries they are including in the
       link.  Set this property to the list of dependent shared libraries of
       an imported library.  The list should be disjoint from the list of
       interface libraries in the INTERFACE_LINK_LIBRARIES property.  On
       platforms requiring dependent shared libraries to be found at link
       time CMake uses this list to add appropriate files or paths to the
       link command line.  Ignored for non-imported targets.

  IMPORTED_LINK_DEPENDENT_LIBRARIES_<CONFIG>
       <CONFIG>-specific version of IMPORTED_LINK_DEPENDENT_LIBRARIES.

       Configuration names correspond to those provided by the project from
       which the target is imported.  If set, this property completely
       overrides the generic property for the named configuration.

  IMPORTED_LINK_INTERFACE_LANGUAGES
       Languages compiled into an IMPORTED static library.

       Set this to the list of languages of source files compiled to produce
       a STATIC IMPORTED library (such as "C" or "CXX").  CMake accounts for
       these languages when computing how to link a target to the imported
       library.  For example, when a C executable links to an imported C++
       static library CMake chooses the C++ linker to satisfy language
       runtime dependencies of the static library.

       This property is ignored for targets that are not STATIC libraries.
       This property is ignored for non-imported targets.

  IMPORTED_LINK_INTERFACE_LANGUAGES_<CONFIG>
       <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LANGUAGES.

       Configuration names correspond to those provided by the project from
       which the target is imported.  If set, this property completely
       overrides the generic property for the named configuration.

  IMPORTED_LINK_INTERFACE_LIBRARIES
       Transitive link interface of an IMPORTED target.

       Set this to the list of libraries whose interface is included when an
       IMPORTED library target is linked to another target.  The libraries
       will be included on the link line for the target.  Unlike the
       LINK_INTERFACE_LIBRARIES property, this property applies to all
       imported target types, including STATIC libraries.  This property is
       ignored for non-imported targets.

       This property is ignored if the target also has a non-empty
       INTERFACE_LINK_LIBRARIES property.

       This property is deprecated.  Use INTERFACE_LINK_LIBRARIES instead.

  IMPORTED_LINK_INTERFACE_LIBRARIES_<CONFIG>
       <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_LIBRARIES.

       Configuration names correspond to those provided by the project from
       which the target is imported.  If set, this property completely
       overrides the generic property for the named configuration.

       This property is ignored if the target also has a non-empty
       INTERFACE_LINK_LIBRARIES property.

       This property is deprecated.  Use INTERFACE_LINK_LIBRARIES instead.

  IMPORTED_LINK_INTERFACE_MULTIPLICITY
       Repetition count for cycles of IMPORTED static libraries.

       This is LINK_INTERFACE_MULTIPLICITY for IMPORTED targets.

  IMPORTED_LINK_INTERFACE_MULTIPLICITY_<CONFIG>
       <CONFIG>-specific version of IMPORTED_LINK_INTERFACE_MULTIPLICITY.

       If set, this property completely overrides the generic property for
       the named configuration.

  IMPORTED_LOCATION
       Full path to the main file on disk for an IMPORTED target.

       Set this to the location of an IMPORTED target file on disk.  For
       executables this is the location of the executable file.  For bundles
       on OS X this is the location of the executable file inside
       Contents/MacOS under the application bundle folder.  For static
       libraries and modules this is the location of the library or module.
       For shared libraries on non-DLL platforms this is the location of the
       shared library.  For frameworks on OS X this is the location of the
       library file symlink just inside the framework folder.  For DLLs this
       is the location of the ".dll" part of the library.  For UNKNOWN
       libraries this is the location of the file to be linked.  Ignored for
       non-imported targets.

       Projects may skip IMPORTED_LOCATION if the configuration-specific
       property IMPORTED_LOCATION_<CONFIG> is set.  To get the location of an
       imported target read one of the LOCATION or LOCATION_<CONFIG>
       properties.

  IMPORTED_LOCATION_<CONFIG>
       <CONFIG>-specific version of IMPORTED_LOCATION property.

       Configuration names correspond to those provided by the project from
       which the target is imported.

  IMPORTED_NO_SONAME
       Specifies that an IMPORTED shared library target has no "soname".

       Set this property to true for an imported shared library file that has
       no "soname" field.  CMake may adjust generated link commands for some
       platforms to prevent the linker from using the path to the library in
       place of its missing soname.  Ignored for non-imported targets.

  IMPORTED_NO_SONAME_<CONFIG>
       <CONFIG>-specific version of IMPORTED_NO_SONAME property.

       Configuration names correspond to those provided by the project from
       which the target is imported.

  IMPORTED_SONAME
       The "soname" of an IMPORTED target of shared library type.

       Set this to the "soname" embedded in an imported shared library.  This
       is meaningful only on platforms supporting the feature.  Ignored for
       non-imported targets.

  IMPORTED_SONAME_<CONFIG>
       <CONFIG>-specific version of IMPORTED_SONAME property.

       Configuration names correspond to those provided by the project from
       which the target is imported.

  IMPORT_PREFIX
       What comes before the import library name.

       Similar to the target property PREFIX, but used for import libraries
       (typically corresponding to a DLL) instead of regular libraries.  A
       target property that can be set to override the prefix (such as "lib")
       on an import library name.

  IMPORT_SUFFIX
       What comes after the import library name.

       Similar to the target property SUFFIX, but used for import libraries
       (typically corresponding to a DLL) instead of regular libraries.  A
       target property that can be set to override the suffix (such as
       ".lib") on an import library name.

  INCLUDE_DIRECTORIES
       List of preprocessor include file search directories.

       This property specifies the list of directories given so far to the
       include_directories command.  This property exists on directories and
       targets.  In addition to accepting values from the include_directories
       command, values may be set directly on any directory or any target
       using the set_property command.  A target gets its initial value for
       this property from the value of the directory property.  A directory
       gets its initial value from its parent directory if it has one.  Both
       directory and target property values are adjusted by calls to the
       include_directories command.

       The target property values are used by the generators to set the
       include paths for the compiler.  See also the include_directories
       command.

       Contents of INCLUDE_DIRECTORIES may use "generator expressions" with
       the syntax "$<...>".  Generator expressions are evaluated during build
       system generation to produce information specific to each build
       configuration.  Valid expressions are:

         $<0:...>                  = empty string (ignores "...")
         $<1:...>                  = content of "..."

         $<STREQUAL:a,b>           = '1' if a is STREQUAL b, else '0'
         $<ANGLE-R>                = A literal '>'. Used to compare strings which contain a '>' for example.
         $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
         $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.
         $<JOIN:list,...>          = joins the list with the content of "..."
         $<TARGET_NAME:...>        = Marks ... as being the name of a target.  This is required if exporting targets to multiple dependent export sets.  The '...' must be a literal name of a target- it may not contain generator expressions.
         $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
         $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.

         $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

       where "tgt" is the name of a target.  Target file expressions produce
       a full path, but _DIR and _NAME versions can produce the directory and
       file name components:

       Note that tgt is not added as a dependency of the target this
       expression is evaluated on.

         $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
         $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

       Boolean expressions:

       Add paths to linker search and installed rpath.

       INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will
       append directories in the linker search path and outside the project
       to the INSTALL_RPATH.  This property is initialized by the value of

       target is created.

  INTERFACE_COMPILE_DEFINITIONS
       List of public compile definitions for a library.

       Targets may populate this property to publish the compile definitions

       Expressions with an implicit 'this' target:

         $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.


  INTERFACE_POSITION_INDEPENDENT_CODE
       Whether consumers need to create a position-independent target

       The INTERFACE_POSITION_INDEPENDENT_CODE property informs consumers of
       this target whether they must set their POSITION_INDEPENDENT_CODE
       property to ON.  If this property is set to ON, then the
       POSITION_INDEPENDENT_CODE property on all consumers will be set to ON.
       Similarly, if this property is set to OFF, then the
       POSITION_INDEPENDENT_CODE property on all consumers will be set to
       OFF.  If this property is undefined, then consumers will determine
       their POSITION_INDEPENDENT_CODE property by other means.  Consumers
       must ensure that the targets that they link to have a consistent
       requirement for their INTERFACE_POSITION_INDEPENDENT_CODE property.

  INTERFACE_SYSTEM_INCLUDE_DIRECTORIES
       List of public system include directories for a library.

       Targets may populate this property to publish the include directories
       which contain system headers, and therefore should not result in
       compiler warnings.  Consuming targets will then mark the same include
       directories as system headers.

       Generator expressions are evaluated during build system generation to
       produce information specific to each build configuration.  Valid
       expressions are:

         $<0:...>                  = empty string (ignores "...")
         $<1:...>                  = content of "..."

       where "tgt" is the name of a target.  Target file expressions produce
       a full path, but _DIR and _NAME versions can produce the directory and
       file name components:

         $<TARGET_FILE_DIR:tgt>/$<TARGET_FILE_NAME:tgt>
         $<TARGET_LINKER_FILE_DIR:tgt>/$<TARGET_LINKER_FILE_NAME:tgt>
         $<TARGET_SONAME_FILE_DIR:tgt>/$<TARGET_SONAME_FILE_NAME:tgt>

       

         $<TARGET_PROPERTY:tgt,prop>   = The value of the property prop on the target tgt.

       Note that tgt is not added as a dependency of the target this
       expression is evaluated on.

         $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
         $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

       Boolean expressions:

         $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'

       where '?' is always either '0' or '1'.

       Expressions with an implicit 'this' target:

         $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.


  INTERPROCEDURAL_OPTIMIZATION
       Enable interprocedural optimization for a target.

       If set to true, enables interprocedural optimizations if they are
       known to be supported by the compiler.

  INTERPROCEDURAL_OPTIMIZATION_<CONFIG>
       Per-configuration interprocedural optimization for a target.

       This is a per-configuration version of INTERPROCEDURAL_OPTIMIZATION.
       If set, this property overrides the generic property for the named
       configuration.

  LABELS
       Specify a list of text labels associated with a target.

       Target label semantics are currently unspecified.

  LIBRARY_OUTPUT_DIRECTORY
       Output directory in which to build LIBRARY target files.

       This property specifies the directory into which library target files
       should be built.  Multi-configuration generators (VS, Xcode) append a
       per-configuration subdirectory to the specified directory.  There are
       three kinds of target files that may be built: archive, library, and
       runtime.  Executables are always treated as runtime targets.  Static
       libraries are always treated as archive targets.  Module libraries are
       always treated as library targets.  For non-DLL platforms shared
       libraries are treated as library targets.  For DLL platforms the DLL
       part of a shared library is treated as a runtime target and the
       corresponding import library is treated as an archive target.  All
       Windows-based systems including Cygwin are DLL platforms.  This
       property is initialized by the value of the variable
       CMAKE_LIBRARY_OUTPUT_DIRECTORY if it is set when a target is created.

  LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
       Per-configuration output directory for LIBRARY target files.

       This is a per-configuration version of LIBRARY_OUTPUT_DIRECTORY, but
       multi-configuration generators (VS, Xcode) do NOT append a
       per-configuration subdirectory to the specified directory.  This
       property is initialized by the value of the variable
       CMAKE_LIBRARY_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
       created.

  LIBRARY_OUTPUT_NAME
       Output name for LIBRARY target files.

       This property specifies the base name for library target files.  It
       overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  There are
       three kinds of target files that may be built: archive, library, and
       runtime.  Executables are always treated as runtime targets.  Static
       libraries are always treated as archive targets.  Module libraries are
       always treated as library targets.  For non-DLL platforms shared
       libraries are treated as library targets.  For DLL platforms the DLL
       part of a shared library is treated as a runtime target and the
       corresponding import library is treated as an archive target.  All
       Windows-based systems including Cygwin are DLL platforms.

  LIBRARY_OUTPUT_NAME_<CONFIG>
       Per-configuration output name for LIBRARY target files.

       This is the configuration-specific version of LIBRARY_OUTPUT_NAME.

  LINKER_LANGUAGE
       Specifies language whose compiler will invoke the linker.

       For executables, shared libraries, and modules, this sets the language
       whose compiler is used to link the target (such as "C" or "CXX").  A
       typical value for an executable is the language of the source file
       providing the program entry point (main).  If not set, the language
       with the highest linker preference value is the default.  See
       documentation of CMAKE_<LANG>_LINKER_PREFERENCE variables.

       If this property is not set by the user, it will be calculated at
       generate-time by CMake.

  LINK_DEPENDS
       Additional files on which a target binary depends for linking.

       Specifies a semicolon-separated list of full-paths to files on which
       the link rule for this target depends.  The target binary will be
       linked if any of the named files is newer than it.

       This property is ignored by non-Makefile generators.  It is intended
       to specify dependencies on "linker scripts" for custom Makefile link
       rules.

  LINK_DEPENDS_NO_SHARED
       Do not depend on linked shared library files.

       Set this property to true to tell CMake generators not to add
       file-level dependencies on the shared library files linked by this
       target.  Modification to the shared libraries will not be sufficient
       to re-link this target.  Logical target-level dependencies will not be
       affected so the linked shared libraries will still be brought up to
       date before this target is built.

       This property is initialized by the value of the variable
       CMAKE_LINK_DEPENDS_NO_SHARED if it is set when a target is created.

  LINK_FLAGS
       Additional flags to use when linking this target.

       The LINK_FLAGS property can be used to add extra flags to the link
       step of a target.  LINK_FLAGS_<CONFIG> will add to the configuration
       <CONFIG>, for example, DEBUG, RELEASE, MINSIZEREL, RELWITHDEBINFO.

  LINK_FLAGS_<CONFIG>
       Per-configuration linker flags for a target.

       This is the configuration-specific version of LINK_FLAGS.

  LINK_INTERFACE_LIBRARIES
       List public interface libraries for a shared library or executable.

       By default linking to a shared library target transitively links to
       targets with which the library itself was linked.  For an executable
       with exports (see the ENABLE_EXPORTS property) no default transitive
       link dependencies are used.  This property replaces the default
       transitive link dependencies with an explicit list.  When the target
       is linked into another target the libraries listed (and recursively
       their link interface libraries) will be provided to the other target
       also.  If the list is empty then no transitive link dependencies will
       be incorporated when this target is linked into another target even if
       the default set is non-empty.  This property is initialized by the
       value of the variable CMAKE_LINK_INTERFACE_LIBRARIES if it is set when
       a target is created.  This property is ignored for STATIC libraries.

       This property is overridden by the INTERFACE_LINK_LIBRARIES property
       if policy CMP0022 is NEW.

       This property is deprecated.  Use INTERFACE_LINK_LIBRARIES instead.

  LINK_INTERFACE_LIBRARIES_<CONFIG>
       Per-configuration list of public interface libraries for a target.

       This is the configuration-specific version of
       LINK_INTERFACE_LIBRARIES.  If set, this property completely overrides
       the generic property for the named configuration.

       This property is overridden by the INTERFACE_LINK_LIBRARIES property
       if policy CMP0022 is NEW.

       This property is deprecated.  Use INTERFACE_LINK_LIBRARIES instead.

  LINK_INTERFACE_MULTIPLICITY
       Repetition count for STATIC libraries with cyclic dependencies.

       When linking to a STATIC library target with cyclic dependencies the
       linker may need to scan more than once through the archives in the
       strongly connected component of the dependency graph.  CMake by
       default constructs the link line so that the linker will scan through
       the component at least twice.  This property specifies the minimum
       number of scans if it is larger than the default.  CMake uses the
       largest value specified by any target in a component.

  LINK_INTERFACE_MULTIPLICITY_<CONFIG>
       Per-configuration repetition count for cycles of STATIC libraries.

       This is the configuration-specific version of
       LINK_INTERFACE_MULTIPLICITY.  If set, this property completely
       overrides the generic property for the named configuration.

  LINK_LIBRARIES
       List of direct link dependencies.

       This property specifies the list of libraries or targets which will be
       used for linking.  In addition to accepting values from the
       target_link_libraries command, values may be set directly on any
       target using the set_property command.

       The target property values are used by the generators to set the link
       libraries for the compiler.  See also the target_link_libraries
       command.

       Contents of LINK_LIBRARIES may use "generator expressions" with the
       syntax "$<...>".  Generator expressions are evaluated during build
       system generation to produce information specific to each build
       configuration.  Valid expressions are:

         $<0:...>                  = empty string (ignores "...")
         $<1:...>                  = content of "..."
         $<CONFIG:cfg>             = '1' if config is "cfg", else '0'

         $<COMMA>                  = A literal ','. Used to compare strings which contain a ',' for example.
         $<SEMICOLON>              = A literal ';'. Used to prevent list expansion on an argument with ';'.

         $<INSTALL_INTERFACE:...>  = content of "..." when the property is exported using install(EXPORT), and empty otherwise.
         $<BUILD_INTERFACE:...>    = content of "..." when the property is exported using export(), or when the target is used by another target in the same buildsystem. Expands to the empty string otherwise.

         $<TARGET_FILE:tgt>        = main file (.exe, .so.1.2, .a)
         $<TARGET_LINKER_FILE:tgt> = file used to link (.a, .lib, .so)
         $<TARGET_SONAME_FILE:tgt> = file with soname (.so.3)

       where "tgt" is the name of a target.  Target file expressions produce
       a full path, but _DIR and _NAME versions can produce the directory and
       file name components:

       expression is evaluated on.

         $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
         $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.

       Boolean expressions:

         $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
         $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
         $<NOT:?>                  = '0' if '?' is '1', else '1'

       where '?' is always either '0' or '1'.

       Expressions with an implicit 'this' target:

         $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.


  LINK_SEARCH_END_STATIC
       End a link line such that static system libraries are used.

       Some linkers support switches such as -Bstatic and -Bdynamic to
       determine whether to use static or shared libraries for -lXXX options.
       CMake uses these options to set the link type for libraries whose full
       paths are not known or (in some cases) are in implicit link
       directories for the platform.  By default CMake adds an option at the
       end of the library list (if necessary) to set the linker search type
       back to its starting type.  This property switches the final linker
       search type to -Bstatic regardless of how it started.  See also
       LINK_SEARCH_START_STATIC.

  LINK_SEARCH_START_STATIC
       Assume the linker looks for static libraries by default.

       Some linkers support switches such as -Bstatic and -Bdynamic to
       determine whether to use static or shared libraries for -lXXX options.
       CMake uses these options to set the link type for libraries whose full
       paths are not known or (in some cases) are in implicit link
       directories for the platform.  By default the linker search type is
       assumed to be -Bdynamic at the beginning of the library list.  This
       property switches the assumption to -Bstatic.  It is intended for use
       when linking an executable statically (e.g.  with the GNU -static
       option).  See also LINK_SEARCH_END_STATIC.

  LOCATION
       Read-only location of a target on disk.

       For an imported target, this read-only property returns the value of
       the LOCATION_<CONFIG> property for an unspecified configuration
       <CONFIG> provided by the target.

       For a non-imported target, this property is provided for compatibility
       with CMake 2.4 and below.  It was meant to get the location of an
       executable target's output file for use in add_custom_command.  The
       path may contain a build-system-specific portion that is replaced at
       build time with the configuration getting built (such as
       "$(ConfigurationName)" in VS).  In CMake 2.6 and above
       add_custom_command automatically recognizes a target name in its
       COMMAND and DEPENDS options and computes the target location.  In
       CMake 2.8.4 and above add_custom_command recognizes generator
       expressions to refer to target locations anywhere in the command.
       Therefore this property is not needed for creating custom commands.

       Do not set properties that affect the location of a target after
       reading this property.  These include properties whose names match
       "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
       "(IMPLIB_)?(PREFIX|SUFFIX)", or "LINKER_LANGUAGE".  Failure to follow
       this rule is not diagnosed and leaves the location of the target
       undefined.

  LOCATION_<CONFIG>
       Read-only property providing a target location on disk.

       A read-only property that indicates where a target's main file is
       located on disk for the configuration <CONFIG>.  The property is
       defined only for library and executable targets.  An imported target
       may provide a set of configurations different from that of the
       importing project.  By default CMake looks for an exact-match but
       otherwise uses an arbitrary available configuration.  Use the
       MAP_IMPORTED_CONFIG_<CONFIG> property to map imported configurations
       explicitly.

       Do not set properties that affect the location of a target after
       reading this property.  These include properties whose names match
       "(RUNTIME|LIBRARY|ARCHIVE)_OUTPUT_(NAME|DIRECTORY)(_<CONFIG>)?",
       "(IMPLIB_)?(PREFIX|SUFFIX)", or "LINKER_LANGUAGE".  Failure to follow
       this rule is not diagnosed and leaves the location of the target
       undefined.

  MACOSX_BUNDLE
       Build an executable as an application bundle on Mac OS X.

       When this property is set to true the executable when built on Mac OS
       X will be created as an application bundle.  This makes it a GUI
       executable that can be launched from the Finder.  See the
       MACOSX_BUNDLE_INFO_PLIST target property for information about
       creation of the Info.plist file for the application bundle.  This
       property is initialized by the value of the variable
       CMAKE_MACOSX_BUNDLE if it is set when a target is created.

  MACOSX_BUNDLE_INFO_PLIST
       Specify a custom Info.plist template for a Mac OS X App Bundle.

       An executable target with MACOSX_BUNDLE enabled will be built as an
       application bundle on Mac OS X.  By default its Info.plist file is
       created by configuring a template called MacOSXBundleInfo.plist.in
       located in the CMAKE_MODULE_PATH.  This property specifies an
       alternative template file name which may be a full path.

       The following target properties may be set to specify content to be
       configured into the file:

         MACOSX_BUNDLE_INFO_STRING
         MACOSX_BUNDLE_ICON_FILE
         MACOSX_BUNDLE_GUI_IDENTIFIER
         MACOSX_BUNDLE_LONG_VERSION_STRING
         MACOSX_BUNDLE_BUNDLE_NAME
         MACOSX_BUNDLE_SHORT_VERSION_STRING
         MACOSX_BUNDLE_BUNDLE_VERSION
         MACOSX_BUNDLE_COPYRIGHT

       CMake variables of the same name may be set to affect all targets in a
       directory that do not have each specific property set.  If a custom
       Info.plist is specified by this property it may of course hard-code
       all the settings instead of using the target properties.

  MACOSX_FRAMEWORK_INFO_PLIST
       Specify a custom Info.plist template for a Mac OS X Framework.

       A library target with FRAMEWORK enabled will be built as a framework
       on Mac OS X.  By default its Info.plist file is created by configuring
       a template called MacOSXFrameworkInfo.plist.in located in the
       CMAKE_MODULE_PATH.  This property specifies an alternative template
       file name which may be a full path.

       The following target properties may be set to specify content to be
       configured into the file:

         MACOSX_FRAMEWORK_ICON_FILE
         MACOSX_FRAMEWORK_IDENTIFIER
         MACOSX_FRAMEWORK_SHORT_VERSION_STRING
         MACOSX_FRAMEWORK_BUNDLE_VERSION

       CMake variables of the same name may be set to affect all targets in a
       directory that do not have each specific property set.  If a custom
       Info.plist is specified by this property it may of course hard-code
       all the settings instead of using the target properties.

  MACOSX_RPATH
       Whether to use rpaths on Mac OS X.

       When this property is set to true, the directory portion of
       the"install_name" field of shared libraries will default to
       "@rpath".Runtime paths will also be embedded in binaries using this
       target.This property is initialized by the value of the variable
       CMAKE_MACOSX_RPATH if it is set when a target is created.

  MAP_IMPORTED_CONFIG_<CONFIG>
       Map from project configuration to IMPORTED target's configuration.

       Set this to the list of configurations of an imported target that may
       be used for the current project's <CONFIG> configuration.  Targets
       imported from another project may not provide the same set of
       configuration names available in the current project.  Setting this
       property tells CMake what imported configurations are suitable for use
       when building the <CONFIG> configuration.  The first configuration in
       the list found to be provided by the imported target is selected.  If
       this property is set and no matching configurations are available,
       then the imported target is considered to be not found.  This property
       is ignored for non-imported targets.

  NAME
       Logical name for the target.

       Read-only logical name for the target as used by CMake.

  NO_SONAME
       Whether to set "soname" when linking a shared library or module.

       Enable this boolean property if a generated shared library or module
       should not have "soname" set.  Default is to set "soname" on all
       shared libraries and modules as long as the platform supports it.
       Generally, use this property only for leaf private libraries or
       plugins.  If you use it on normal shared libraries which other targets
       link against, on some platforms a linker will insert a full path to
       the library (as specified at link time) into the dynamic section of
       the dependent binary.  Therefore, once installed, dynamic loader may
       eventually fail to locate the library for the binary.

  OSX_ARCHITECTURES
       Target specific architectures for OS X.

       The OSX_ARCHITECTURES property sets the target binary architecture for
       targets on OS X.  This property is initialized by the value of the
       variable CMAKE_OSX_ARCHITECTURES if it is set when a target is
       created.  Use OSX_ARCHITECTURES_<CONFIG> to set the binary
       architectures on a per-configuration basis.  <CONFIG> is an upper-case
       name (ex: "OSX_ARCHITECTURES_DEBUG").

  OSX_ARCHITECTURES_<CONFIG>
       Per-configuration OS X binary architectures for a target.

       This property is the configuration-specific version of
       OSX_ARCHITECTURES.

  OUTPUT_NAME
       Output name for target files.

       This sets the base name for output files created for an executable or
       library target.  If not set, the logical target name is used by
       default.

  OUTPUT_NAME_<CONFIG>
       Per-configuration target file base name.

       This is the configuration-specific version of OUTPUT_NAME.

  PDB_NAME
       Output name for MS debug symbols .pdb file from linker.

       Set the base name for debug symbols file created for an executable or
       shared library target.  If not set, the logical target name is used by
       default.

       This property is not implemented by the Visual Studio 6 generator.

  PDB_NAME_<CONFIG>
       Per-configuration name for MS debug symbols .pdb file.

       This is the configuration-specific version of PDB_NAME.

       This property is not implemented by the Visual Studio 6 generator.

  PDB_OUTPUT_DIRECTORY
       Output directory for MS debug symbols .pdb file from linker.

       This property specifies the directory into which the MS debug symbols
       will be placed by the linker.  This property is initialized by the
       value of the variable CMAKE_PDB_OUTPUT_DIRECTORY if it is set when a
       target is created.

       This property is not implemented by the Visual Studio 6 generator.

  PDB_OUTPUT_DIRECTORY_<CONFIG>
       Per-configuration output directory for MS debug symbols .pdb files.

       This is a per-configuration version of PDB_OUTPUT_DIRECTORY, but
       multi-configuration generators (VS, Xcode) do NOT append a
       per-configuration subdirectory to the specified directory.  This
       property is initialized by the value of the variable
       CMAKE_PDB_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
       created.

       This property is not implemented by the Visual Studio 6 generator.

  POSITION_INDEPENDENT_CODE
       Whether to create a position-independent target

       The POSITION_INDEPENDENT_CODE property determines whether position
       independent executables or shared libraries will be created.  This
       property is true by default for SHARED and MODULE library targets and
       false otherwise.  This property is initialized by the value of the
       variable CMAKE_POSITION_INDEPENDENT_CODE if it is set when a target is
       created.

  POST_INSTALL_SCRIPT
       Deprecated install support.

       The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
       way to specify CMake scripts to run before and after installing a
       target.  They are used only when the old INSTALL_TARGETS command is
       used to install the target.  Use the INSTALL command instead.

  PREFIX
       What comes before the library name.

       A target property that can be set to override the prefix (such as
       "lib") on a library name.

  PRE_INSTALL_SCRIPT
       Deprecated install support.

       The PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT properties are the old
       way to specify CMake scripts to run before and after installing a
       target.  They are used only when the old INSTALL_TARGETS command is
       used to install the target.  Use the INSTALL command instead.

  PRIVATE_HEADER
       Specify private header files in a FRAMEWORK shared library target.

       Shared library targets marked with the FRAMEWORK property generate
       frameworks on OS X and normal shared libraries on other platforms.
       This property may be set to a list of header files to be placed in the
       PrivateHeaders directory inside the framework folder.  On non-Apple
       platforms these headers may be installed using the PRIVATE_HEADER
       option to the install(TARGETS) command.

  PROJECT_LABEL
       Change the name of a target in an IDE.

       Can be used to change the name of the target in an IDE like Visual
       Studio.

  PUBLIC_HEADER
       Specify public header files in a FRAMEWORK shared library target.

       Shared library targets marked with the FRAMEWORK property generate
       frameworks on OS X and normal shared libraries on other platforms.
       This property may be set to a list of header files to be placed in the
       Headers directory inside the framework folder.  On non-Apple platforms
       these headers may be installed using the PUBLIC_HEADER option to the
       install(TARGETS) command.

  RESOURCE
       Specify resource files in a FRAMEWORK shared library target.

       Shared library targets marked with the FRAMEWORK property generate
       frameworks on OS X and normal shared libraries on other platforms.
       This property may be set to a list of files to be placed in the
       Resources directory inside the framework folder.  On non-Apple
       platforms these files may be installed using the RESOURCE option to
       the install(TARGETS) command.

  RULE_LAUNCH_COMPILE
       Specify a launcher for compile rules.

       See the global property of the same name for details.  This overrides
       the global and directory property for a target.

  RULE_LAUNCH_CUSTOM
       Specify a launcher for custom rules.

       See the global property of the same name for details.  This overrides
       the global and directory property for a target.

  RULE_LAUNCH_LINK
       Specify a launcher for link rules.

       See the global property of the same name for details.  This overrides
       the global and directory property for a target.

  RUNTIME_OUTPUT_DIRECTORY
       Output directory in which to build RUNTIME target files.

       This property specifies the directory into which runtime target files
       should be built.  Multi-configuration generators (VS, Xcode) append a
       per-configuration subdirectory to the specified directory.  There are
       three kinds of target files that may be built: archive, library, and
       runtime.  Executables are always treated as runtime targets.  Static
       libraries are always treated as archive targets.  Module libraries are
       always treated as library targets.  For non-DLL platforms shared
       libraries are treated as library targets.  For DLL platforms the DLL
       part of a shared library is treated as a runtime target and the
       corresponding import library is treated as an archive target.  All
       Windows-based systems including Cygwin are DLL platforms.  This
       property is initialized by the value of the variable
       CMAKE_RUNTIME_OUTPUT_DIRECTORY if it is set when a target is created.

  RUNTIME_OUTPUT_DIRECTORY_<CONFIG>
       Per-configuration output directory for RUNTIME target files.

       This is a per-configuration version of RUNTIME_OUTPUT_DIRECTORY, but
       multi-configuration generators (VS, Xcode) do NOT append a
       per-configuration subdirectory to the specified directory.  This
       property is initialized by the value of the variable
       CMAKE_RUNTIME_OUTPUT_DIRECTORY_<CONFIG> if it is set when a target is
       created.

  RUNTIME_OUTPUT_NAME
       Output name for RUNTIME target files.

       This property specifies the base name for runtime target files.  It
       overrides OUTPUT_NAME and OUTPUT_NAME_<CONFIG> properties.  There are
       three kinds of target files that may be built: archive, library, and
       runtime.  Executables are always treated as runtime targets.  Static
       libraries are always treated as archive targets.  Module libraries are
       always treated as library targets.  For non-DLL platforms shared
       libraries are treated as library targets.  For DLL platforms the DLL
       part of a shared library is treated as a runtime target and the
       corresponding import library is treated as an archive target.  All
       Windows-based systems including Cygwin are DLL platforms.

  RUNTIME_OUTPUT_NAME_<CONFIG>
       Per-configuration output name for RUNTIME target files.

       This is the configuration-specific version of RUNTIME_OUTPUT_NAME.

  SKIP_BUILD_RPATH
       Should rpaths be used for the build tree.

       SKIP_BUILD_RPATH is a boolean specifying whether to skip automatic
       generation of an rpath allowing the target to run from the build tree.
       This property is initialized by the value of the variable
       CMAKE_SKIP_BUILD_RPATH if it is set when a target is created.

  SOURCES
       Source names specified for a target.

       Read-only list of sources specified for a target.  The names returned
       are suitable for passing to the set_source_files_properties command.

  SOVERSION
       What version number is this target.

       For shared libraries VERSION and SOVERSION can be used to specify the
       build version and API version respectively.  When building or
       installing appropriate symlinks are created if the platform supports
       symlinks and the linker supports so-names.  If only one of both is
       specified the missing is assumed to have the same version number.
       SOVERSION is ignored if NO_SONAME property is set.  For shared
       libraries and executables on Windows the VERSION attribute is parsed
       to extract a "major.minor" version number.  These numbers are used as
       the image version of the binary.

  STATIC_LIBRARY_FLAGS
       Extra flags to use when linking static libraries.

       Extra flags to use when linking a static library.

  STATIC_LIBRARY_FLAGS_<CONFIG>
       Per-configuration flags for creating a static library.

       This is the configuration-specific version of STATIC_LIBRARY_FLAGS.

  SUFFIX
       What comes after the target name.

       A target property that can be set to override the suffix (such as
       ".so" or ".exe") on the name of a library, module or executable.

  TYPE
       The type of the target.

       This read-only property can be used to test the type of the given
       target.  It will be one of STATIC_LIBRARY, MODULE_LIBRARY,
       SHARED_LIBRARY, EXECUTABLE or one of the internal target types.

  VERSION
       What version number is this target.

       For shared libraries VERSION and SOVERSION can be used to specify the
       build version and API version respectively.  When building or
       installing appropriate symlinks are created if the platform supports
       symlinks and the linker supports so-names.  If only one of both is
       specified the missing is assumed to have the same version number.  For
       executables VERSION can be used to specify the build version.  When
       building or installing appropriate symlinks are created if the
       platform supports symlinks.  For shared libraries and executables on
       Windows the VERSION attribute is parsed to extract a "major.minor"
       version number.  These numbers are used as the image version of the
       binary.

  VISIBILITY_INLINES_HIDDEN
       Whether to add a compile flag to hide symbols of inline functions

       The VISIBILITY_INLINES_HIDDEN property determines whether a flag for
       hiding symbols for inline functions.  the value passed used in a
       visibility related compile option, such as -fvisibility=.  This
       property only has an affect for libraries and executables with
       exports.  This property is initialized by the value of the variable
       CMAKE_VISIBILITY_INLINES_HIDDEN if it is set when a target is created.

  VS_DOTNET_REFERENCES
       Visual Studio managed project .NET references

       Adds one or more semicolon-delimited .NET references to a generated
       Visual Studio project.  For example, "System;System.Windows.Forms".

  VS_DOTNET_TARGET_FRAMEWORK_VERSION
       Specify the .NET target framework version.

       Used to specify the .NET target framework version for C++/CLI.  For
       example, "v4.5".

  VS_GLOBAL_<variable>
       Visual Studio project-specific global variable.

       Tell the Visual Studio generator to set the global variable
       '<variable>' to a given value in the generated Visual Studio project.
       Ignored on other generators.  Qt integration works better if
       VS_GLOBAL_QtVersion is set to the version FindQt4.cmake found.  For
       example, "4.7.3"

  VS_GLOBAL_KEYWORD
       Visual Studio project keyword.

       Sets the "keyword" attribute for a generated Visual Studio project.
       Defaults to "Win32Proj".  You may wish to override this value with
       "ManagedCProj", for example, in a Visual Studio managed C++ unit test
       project.

  VS_GLOBAL_PROJECT_TYPES
       Visual Studio project type(s).

       Can be set to one or more UUIDs recognized by Visual Studio to
       indicate the type of project.  This value is copied verbatim into the
       generated project file.  Example for a managed C++ unit testing
       project:

        {3AC096D0-A1C2-E12C-1390-A8335801FDAB};{8BC9CEB8-8B4A-11D0-8D11-00A0C91BC942}

       UUIDs are semicolon-delimited.

  VS_GLOBAL_ROOTNAMESPACE
       Visual Studio project root namespace.

       Sets the "RootNamespace" attribute for a generated Visual Studio
       project.  The attribute will be generated only if this is set.

  VS_KEYWORD
       Visual Studio project keyword.

       Can be set to change the visual studio keyword, for example Qt
       integration works better if this is set to Qt4VSv1.0.

  VS_SCC_AUXPATH
       Visual Studio Source Code Control Aux Path.

       Can be set to change the visual studio source code control auxpath
       property.

  VS_SCC_LOCALPATH
       Visual Studio Source Code Control Local Path.

       Can be set to change the visual studio source code control local path
       property.

       Can be set to enable C++/CX language extensions.

  VS_WINRT_REFERENCES
       Visual Studio project Windows Runtime Metadata references

       Adds one or more semicolon-delimited WinRT references to a generated
       Visual Studio project.  For example, "Windows;Windows.UI.Core".

  WIN32_EXECUTABLE
       Build an executable with a WinMain entry point on windows.

       When this property is set to true the executable when linked on
       Windows will be created with a WinMain() entry point instead of just
       main().  This makes it a GUI executable instead of a console
       application.  See the CMAKE_MFC_FLAG variable documentation to
       configure use of MFC for WinMain executables.  This property is
       initialized by the value of the variable CMAKE_WIN32_EXECUTABLE if it
       is set when a target is created.

  XCODE_ATTRIBUTE_<an-attribute>
       Set Xcode target attributes directly.

       Tell the Xcode generator to set '<an-attribute>' to a given value in
       the generated Xcode project.  Ignored on other generators.

------------------------------------------------------------------------------
Properties on Tests

  ATTACHED_FILES
       Attach a list of files to a dashboard submission.

       Set this property to a list of files that will be encoded and
       submitted to the dashboard as an addition to the test result.

  ATTACHED_FILES_ON_FAIL
       Attach a list of files to a dashboard submission if the test fails.

       Same as ATTACHED_FILES, but these files will only be included if the
       test does not pass.

  COST
       Set this to a floating point value.  Tests in a test set will be run
       in descending order of cost.

       This property describes the cost of a test.  You can explicitly set
       this value; tests with higher COST values will run first.

  DEPENDS
       Specifies that this test should only be run after the specified list
       of tests.

       Set this to a list of tests that must finish before this test is run.

  ENVIRONMENT
       Specify environment variables that should be defined for running a
       test.

       If set to a list of environment variables and values of the form
       MYVAR=value those environment variables will be defined while running
       the test.  The environment is restored to its previous state after the
       test is done.

  FAIL_REGULAR_EXPRESSION
       If the output matches this regular expression the test will fail.

       If set, if the output matches one of specified regular expressions,
       the test will fail.For example: FAIL_REGULAR_EXPRESSION
       "[^a-z]Error;ERROR;Failed"

  LABELS
       Specify a list of text labels associated with a test.

       The list is reported in dashboard submissions.

  MEASUREMENT
       Specify a CDASH measurement and value to be reported for a test.

       If set to a name then that name will be reported to CDASH as a named
       measurement with a value of 1.  You may also specify a value by
       setting MEASUREMENT to "measurement=value".

  PASS_REGULAR_EXPRESSION
       The output must match this regular expression for the test to pass.

       If set, the test output will be checked against the specified regular
       expressions and at least one of the regular expressions has to match,
       otherwise the test will fail.

  PROCESSORS
       How many process slots this test requires

       Denotes the number of processors that this test will require.  This is
       typically used for MPI tests, and should be used in conjunction with
       the ctest_test PARALLEL_LEVEL option.

  REQUIRED_FILES
       List of files required to run the test.

       If set to a list of files, the test will not be run unless all of the
       files exist.

  RESOURCE_LOCK
       Specify a list of resources that are locked by this test.

       If multiple tests specify the same resource lock, they are guaranteed
       not to run concurrently.

  RUN_SERIAL
       Do not run this test in parallel with any other test.

       Use this option in conjunction with the ctest_test PARALLEL_LEVEL
       option to specify that this test should not be run in parallel with
       any other tests.

  TIMEOUT
       How many seconds to allow for this test.

       This property if set will limit a test to not take more than the
       specified number of seconds to run.  If it exceeds that the test
       process will be killed and ctest will move to the next test.  This
       setting takes precedence over CTEST_TESTING_TIMEOUT.

  WILL_FAIL
       If set to true, this will invert the pass/fail flag of the test.

       This property can be used for tests that are expected to fail and
       return a non zero return code.

  WORKING_DIRECTORY
       The directory from which the test executable will be called.

       If this is not set it is called from the directory the test executable
       is located in.

------------------------------------------------------------------------------
Properties on Source Files

  ABSTRACT
       Is this source file an abstract class.

       A property on a source file that indicates if the source file
       represents a class that is abstract.  This only makes sense for
       languages that have a notion of an abstract class and it is only used
       by some tools that wrap classes into other languages.

  COMPILE_DEFINITIONS
       Preprocessor definitions for compiling a source file.

       The COMPILE_DEFINITIONS property may be set to a semicolon-separated
       list of preprocessor definitions using the syntax VAR or VAR=value.
       Function-style definitions are not supported.  CMake will
       automatically escape the value correctly for the native build system
       (note that CMake language syntax may require escapes to specify some
       values).  This property may be set on a per-configuration basis using
       the name COMPILE_DEFINITIONS_<CONFIG> where <CONFIG> is an upper-case
       name (ex.  "COMPILE_DEFINITIONS_DEBUG").

       CMake will automatically drop some definitions that are not supported
       by the native build tool.  The VS6 IDE does not support definition
       values with spaces (but NMake does).  Xcode does not support
       per-configuration definitions on source files.

       Disclaimer: Most native build tools have poor support for escaping
       certain values.  CMake has work-arounds for many cases but some values
       may just not be possible to pass correctly.  If a value does not seem
       to be escaped correctly, do not attempt to work-around the problem by
       adding escape sequences to the value.  Your work-around may break in a
       future version of CMake that has improved escape support.  Instead
       consider defining the macro in a (configured) header file.  Then
       report the limitation.  Known limitations include:

         #          - broken almost everywhere
         ;          - broken in VS IDE 7.0 and Borland Makefiles
         ,          - broken in VS IDE
         %          - broken in some cases in NMake
         & |        - broken in some cases on MinGW
         ^ < > \"   - broken in most Make tools on Windows

       CMake does not reject these values outright because they do work in
       some cases.  Use with caution.

  COMPILE_DEFINITIONS_<CONFIG>
       Per-configuration preprocessor definitions on a source file.

       This is the configuration-specific version of COMPILE_DEFINITIONS.
       Note that Xcode does not support per-configuration source file flags
       so this property will be ignored by the Xcode generator.

  COMPILE_FLAGS
       Additional flags to be added when compiling this source file.

       These flags will be added to the list of compile flags when this
       source file builds.  Use COMPILE_DEFINITIONS to pass additional
       preprocessor definitions.

  EXTERNAL_OBJECT
       If set to true then this is an object file.

       If this property is set to true then the source file is really an
       object file and should not be compiled.  It will still be linked into
       the target though.

  Fortran_FORMAT
       Set to FIXED or FREE to indicate the Fortran source layout.

       This property tells CMake whether a given Fortran source file uses
       fixed-format or free-format.  CMake will pass the corresponding format
       flag to the compiler.  Consider using the target-wide Fortran_FORMAT
       property if all source files in a target share the same format.

  GENERATED
       Is this source file generated as part of the build process.

       If a source file is generated by the build process CMake will handle
       it differently in terms of dependency checking etc.  Otherwise having
       a non-existent source file could create problems.

  HEADER_FILE_ONLY
       Is this source file only a header file.

       A property on a source file that indicates if the source file is a
       header file with no associated implementation.  This is set
       automatically based on the file extension and is used by CMake to
       determine if certain dependency information should be computed.

  KEEP_EXTENSION
       Make the output file have the same extension as the source file.

       If this property is set then the file extension of the output file
       will be the same as that of the source file.  Normally the output file
       extension is computed based on the language of the source file, for
       example .cxx will go to a .o extension.

  LABELS
       Specify a list of text labels associated with a source file.

       This property has meaning only when the source file is listed in a
       target whose LABELS property is also set.  No other semantics are
       currently specified.

  LANGUAGE
       What programming language is the file.

       A property that can be set to indicate what programming language the
       source file is.  If it is not set the language is determined based on
       the file extension.  Typical values are CXX C etc.  Setting this
       property for a file means this file will be compiled.  Do not set this
       for headers or files that should not be compiled.

  LOCATION
       The full path to a source file.

       A read only property on a SOURCE FILE that contains the full path to
       the source file.

  MACOSX_PACKAGE_LOCATION
       Place a source file inside a Mac OS X bundle, CFBundle, or framework.

       Executable targets with the MACOSX_BUNDLE property set are built as
       Mac OS X application bundles on Apple platforms.  Shared library
       targets with the FRAMEWORK property set are built as Mac OS X
       frameworks on Apple platforms.  Module library targets with the BUNDLE
       property set are built as Mac OS X CFBundle bundles on Apple
       platforms.  Source files listed in the target with this property set
       will be copied to a directory inside the bundle or framework content
       folder specified by the property value.  For bundles the content
       folder is "<name>.app/Contents".  For frameworks the content folder is
       "<name>.framework/Versions/<version>".  For cfbundles the content
       folder is "<name>.bundle/Contents" (unless the extension is changed).
       See the PUBLIC_HEADER, PRIVATE_HEADER, and RESOURCE target properties
       for specifying files meant for Headers, PrivateHeaders, or Resources
       directories.

  OBJECT_DEPENDS
       Additional files on which a compiled object file depends.

       Specifies a semicolon-separated list of full-paths to files on which
       any object files compiled from this source file depend.  An object
       file will be recompiled if any of the named files is newer than it.

       This property need not be used to specify the dependency of a source
       file on a generated header file that it includes.  Although the
       property was originally introduced for this purpose, it is no longer
       necessary.  If the generated header file is created by a custom
       command in the same target as the source file, the automatic
       dependency scanning process will recognize the dependency.  If the
       generated header file is created by another target, an inter-target
       dependency should be created with the add_dependencies command (if one
       does not already exist due to linking relationships).

  OBJECT_OUTPUTS
       Additional outputs for a Makefile rule.

       Additional outputs created by compilation of this source file.  If any
       of these outputs is missing the object will be recompiled.  This is
       supported only on Makefile generators and will be ignored on other
       generators.

  SYMBOLIC
       Is this just a name for a rule.

       If SYMBOLIC (boolean) is set to true the build system will be informed
       that the source file is not actually created on disk but instead used
       as a symbolic name for a build rule.

  WRAP_EXCLUDE
       Exclude this source file from any code wrapping techniques.

       Some packages can wrap source files into alternate languages to
       provide additional functionality.  For example, C++ code can be
       wrapped into Java or Python etc using SWIG etc.  If WRAP_EXCLUDE is
       set to true (1 etc) that indicates that this source file should not be
       wrapped.

------------------------------------------------------------------------------
Properties on Cache Entries

  ADVANCED
       True if entry should be hidden by default in GUIs.

       This is a boolean value indicating whether the entry is considered
       interesting only for advanced configuration.  The mark_as_advanced()
       command modifies this property.

  HELPSTRING
       Help associated with entry in GUIs.

       This string summarizes the purpose of an entry to help users set it
       through a CMake GUI.

  MODIFIED
       Internal management property.  Do not set or get.

       This is an internal cache entry property managed by CMake to track
       interactive user modification of entries.  Ignore it.

  STRINGS
       Enumerate possible STRING entry values for GUI selection.

       For cache entries with type STRING, this enumerates a set of values.
       CMake GUIs may use this to provide a selection widget instead of a
       generic string entry field.  This is for convenience only.  CMake does
       not enforce that the value matches one of those listed.

  TYPE
       Widget type for entry in GUIs.

       Cache entry values are always strings, but CMake GUIs present widgets
       to help users set values.  The GUIs use this property as a hint to
       determine the widget type.  Valid TYPE values are:

         BOOL          = Boolean ON/OFF value.
         PATH          = Path to a directory.
         FILEPATH      = Path to a file.
         STRING        = Generic string value.
         INTERNAL      = Do not present in GUI at all.
         STATIC        = Value managed by CMake, do not change.
         UNINITIALIZED = Type not yet specified.

       Generally the TYPE of a cache entry should be set by the command which
       creates it (set, option, find_library, etc.).

  VALUE
       Value of a cache entry.

       This property maps to the actual value of a cache entry.  Setting this
       property always sets the value without checking, so use with care.

------------------------------------------------------------------------------
Compatibility Commands

  CMake Compatibility Listfile Commands - Obsolete commands supported by CMake for compatibility.

This is the documentation for now obsolete listfile commands from previous
CMake versions, which are still supported for compatibility reasons.  You
should instead use the newer, faster and shinier new commands.  ;-)

  build_name
       Deprecated.  Use ${CMAKE_SYSTEM} and ${CMAKE_CXX_COMPILER} instead.

         build_name(variable)

       Sets the specified variable to a string representing the platform and
       compiler settings.  These values are now available through the
       CMAKE_SYSTEM and CMAKE_CXX_COMPILER variables.

  exec_program
       Deprecated.  Use the execute_process() command instead.

       Run an executable program during the processing of the CMakeList.txt
       file.

         exec_program(Executable [directory in which to run]
                      [ARGS <arguments to executable>]
                      [OUTPUT_VARIABLE <var>]
                      [RETURN_VALUE <var>])

       The executable is run in the optionally specified directory.  The
       executable can include arguments if it is double quoted, but it is
       better to use the optional ARGS argument to specify arguments to the
       program.  This is because cmake will then be able to escape spaces in
       the executable path.  An optional argument OUTPUT_VARIABLE specifies a
       variable in which to store the output.  To capture the return value of
       the execution, provide a RETURN_VALUE.  If OUTPUT_VARIABLE is
       specified, then no output will go to the stdout/stderr of the console
       running cmake.


  export_library_dependencies
       Deprecated.  Use INSTALL(EXPORT) or EXPORT command.

       This command generates an old-style library dependencies file.
       Projects requiring CMake 2.6 or later should not use the command.  Use
       instead the install(EXPORT) command to help export targets from an
       installation tree and the export() command to export targets from a
       build tree.

       The old-style library dependencies file does not take into account
       per-configuration names of libraries or the LINK_INTERFACE_LIBRARIES
       target property.

         export_library_dependencies(<file> [APPEND])

       Create a file named <file> that can be included into a CMake listfile
       with the INCLUDE command.  The file will contain a number of SET
       commands that will set all the variables needed for library dependency
       information.  This should be the last command in the top level
       CMakeLists.txt file of the project.  If the APPEND option is
       specified, the SET commands will be appended to the given file instead
       of replacing it.

  install_files
       Deprecated.  Use the install(FILES ) command instead.

       This command has been superceded by the install command.  It is
       provided for compatibility with older CMake code.  The FILES form is
       directly replaced by the FILES form of the install command.  The
       regexp form can be expressed more clearly using the GLOB form of the
       file command.

         install_files(<dir> extension file file ...)

       Create rules to install the listed files with the given extension into
       the given directory.  Only files existing in the current source tree
       or its corresponding location in the binary tree may be listed.  If a
       file specified already has an extension, that extension will be
       removed first.  This is useful for providing lists of source files
       such as foo.cxx when you want the corresponding foo.h to be installed.
       A typical extension is '.h'.

         install_files(<dir> regexp)

       Any files in the current source directory that match the regular
       expression will be installed.

         install_files(<dir> FILES file file ...)

       Any files listed after the FILES keyword will be installed explicitly
       from the names given.  Full paths are allowed in this form.

       The directory <dir> is relative to the installation prefix, which is
       stored in the variable CMAKE_INSTALL_PREFIX.

  install_programs
       Deprecated.  Use the install(PROGRAMS ) command instead.

       This command has been superceded by the install command.  It is
       provided for compatibility with older CMake code.  The FILES form is
       directly replaced by the PROGRAMS form of the INSTALL command.  The
       regexp form can be expressed more clearly using the GLOB form of the
       FILE command.

         install_programs(<dir> file1 file2 [file3 ...])
         install_programs(<dir> FILES file1 [file2 ...])

       Create rules to install the listed programs into the given directory.
       Use the FILES argument to guarantee that the file list version of the
       command will be used even when there is only one argument.

         install_programs(<dir> regexp)

       In the second form any program in the current source directory that
       matches the regular expression will be installed.

       This command is intended to install programs that are not built by
       cmake, such as shell scripts.  See the TARGETS form of the INSTALL
       command to create installation rules for targets built by cmake.

       The directory <dir> is relative to the installation prefix, which is
       stored in the variable CMAKE_INSTALL_PREFIX.

  install_targets
       Deprecated.  Use the install(TARGETS ) command instead.

       This command has been superceded by the install command.  It is
       provided for compatibility with older CMake code.

         install_targets(<dir> [RUNTIME_DIRECTORY dir] target target)

       Create rules to install the listed targets into the given directory.
       The directory <dir> is relative to the installation prefix, which is
       stored in the variable CMAKE_INSTALL_PREFIX.  If RUNTIME_DIRECTORY is
       specified, then on systems with special runtime files (Windows DLL),
       the files will be copied to that directory.

  link_libraries
       Deprecated.  Use the target_link_libraries() command instead.

       Link libraries to all targets added later.

         link_libraries(library1 <debug | optimized> library2 ...)

       Specify a list of libraries to be linked into any following targets
       (typically added with the add_executable or add_library calls).  This
       command is passed down to all subdirectories.  The debug and optimized
       strings may be used to indicate that the next library listed is to be
       used only for that specific type of build.

  make_directory
       Deprecated.  Use the file(MAKE_DIRECTORY ) command instead.

         make_directory(directory)

       Creates the specified directory.  Full paths should be given.  Any
       parent directories that do not exist will also be created.  Use with
       care.

  output_required_files
       Deprecated.  Approximate C preprocessor dependency scanning.

       This command exists only because ancient CMake versions provided it.
       CMake handles preprocessor dependency scanning automatically using a
       more advanced scanner.

         output_required_files(srcfile outputfile)

       Outputs a list of all the source files that are required by the
       specified srcfile.  This list is written into outputfile.  This is
       similar to writing out the dependencies for srcfile except that it
       jumps from .h files into .cxx, .c and .cpp files if possible.

  remove
       Deprecated.  Use the list(REMOVE_ITEM ) command instead.

         remove(VAR VALUE VALUE ...)

       Removes VALUE from the variable VAR.  This is typically used to remove
       entries from a vector (e.g.  semicolon separated list).  VALUE is
       expanded.

  subdir_depends
       Deprecated.  Does nothing.

         subdir_depends(subdir dep1 dep2 ...)

       Does not do anything.  This command used to help projects order
       parallel builds correctly.  This functionality is now automatic.

  subdirs
       Deprecated.  Use the add_subdirectory() command instead.

       Add a list of subdirectories to the build.

         subdirs(dir1 dir2 ...[EXCLUDE_FROM_ALL exclude_dir1 exclude_dir2 ...]
                 [PREORDER] )

       Add a list of subdirectories to the build.  The add_subdirectory
       command should be used instead of subdirs although subdirs will still
       work.  This will cause any CMakeLists.txt files in the sub directories
       to be processed by CMake.  Any directories after the PREORDER flag are
       traversed first by makefile builds, the PREORDER flag has no effect on
       IDE projects.  Any directories after the EXCLUDE_FROM_ALL marker will
       not be included in the top level makefile or project file.  This is
       useful for having CMake create makefiles or projects for a set of
       examples in a project.  You would want CMake to generate makefiles or
       project files for all the examples at the same time, but you would not
       want them to show up in the top level project or be built each time
       make is run from the top.

  use_mangled_mesa
       Copy mesa headers for use in combination with system GL.

         use_mangled_mesa(PATH_TO_MESA OUTPUT_DIRECTORY)

       The path to mesa includes, should contain gl_mangle.h.  The mesa
       headers are copied to the specified output directory.  This allows
       mangled mesa headers to override other GL headers by being added to
       the include directory path earlier.

  utility_source
       Specify the source tree of a third-party utility.

         utility_source(cache_entry executable_name
                        path_to_source [file1 file2 ...])

       When a third-party utility's source is included in the distribution,
       this command specifies its location and name.  The cache entry will
       not be set unless the path_to_source and all listed files exist.  It
       is assumed that the source tree of the utility will have been built
       before it is needed.

       When cross compiling CMake will print a warning if a utility_source()
       command is executed, because in many cases it is used to build an
       executable which is executed later on.  This doesn't work when cross
       compiling, since the executable can run only on their target platform.
       So in this case the cache entry has to be adjusted manually so it
       points to an executable which is runnable on the build host.

  variable_requires
       Deprecated.  Use the if() command instead.

       Assert satisfaction of an option's required variables.

         variable_requires(TEST_VARIABLE RESULT_VARIABLE
                           REQUIRED_VARIABLE1
                           REQUIRED_VARIABLE2 ...)

       The first argument (TEST_VARIABLE) is the name of the variable to be
       tested, if that variable is false nothing else is done.  If
       TEST_VARIABLE is true, then the next argument (RESULT_VARIABLE) is a
       variable that is set to true if all the required variables are set.
       The rest of the arguments are variables that must be true or not set
       to NOTFOUND to avoid an error.  If any are not true, an error is
       reported.

  write_file
       Deprecated.  Use the file(WRITE ) command instead.

         write_file(filename "message to write"... [APPEND])

       The first argument is the file name, the rest of the arguments are
       messages to write.  If the argument APPEND is specified, then the
       message will be appended.

       NOTE 1: file(WRITE ...  and file(APPEND ...  do exactly the same as
       this one but add some more functionality.

       NOTE 2: When using write_file the produced file cannot be used as an
       input to CMake (CONFIGURE_FILE, source file ...) because it will lead
       to an infinite loop.  Use configure_file if you want to generate input
       files to CMake.

------------------------------------------------------------------------------
Standard CMake Modules

The following modules are provided with CMake.  They can be used with
INCLUDE(ModuleName).

  CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.

This is the documentation for the modules and scripts coming with CMake.
Using these modules you can check the computer system for installed software
packages, features of the compiler and the existence of headers to name just
a few.

  AddFileDependencies
       ADD_FILE_DEPENDENCIES(source_file depend_files...)

       Adds the given files as dependencies to source_file


  BundleUtilities
       Functions to help assemble a standalone bundle application.

       A collection of CMake utility functions useful for dealing with .app
       bundles on the Mac and bundle-like directories on any OS.

       The following functions are provided by this module:

          fixup_bundle
          copy_and_fixup_bundle
          verify_app
          get_bundle_main_executable
          get_dotapp_dir
          get_bundle_and_executable
          get_bundle_all_executables
          get_item_key
          clear_bundle_keys
          set_bundle_key_values
          get_bundle_keys
          copy_resolved_item_into_bundle
          copy_resolved_framework_into_bundle
          fixup_bundle_item
          verify_bundle_prerequisites
          verify_bundle_symlinks

       Requires CMake 2.6 or greater because it uses function, break and
       PARENT_SCOPE.  Also depends on GetPrerequisites.cmake.

         FIXUP_BUNDLE(<app> <libs> <dirs>)

       Fix up a bundle in-place and make it standalone, such that it can be
       drag-n-drop copied to another machine and run on that machine as long
       as all of the system libraries are compatible.

       If you pass plugins to fixup_bundle as the libs parameter, you should
       install them or copy them into the bundle before calling fixup_bundle.
       The "libs" parameter is a list of libraries that must be fixed up, but
       that cannot be determined by otool output analysis.  (i.e., plugins)

       Gather all the keys for all the executables and libraries in a bundle,
       and then, for each key, copy each prerequisite into the bundle.  Then
       fix each one up according to its own list of prerequisites.

       Then clear all the keys and call verify_app on the final bundle to
       ensure that it is truly standalone.

         COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)

       Makes a copy of the bundle <src> at location <dst> and then fixes up
       the new copied bundle in-place at <dst>...

         VERIFY_APP(<app>)

       Verifies that an application <app> appears valid based on running
       analysis tools on it.  Calls "message(FATAL_ERROR" if the application
       is not verified.

         GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)

       The result will be the full path name of the bundle's main executable
       file or an "error:" prefixed string if it could not be determined.

         GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)

       Returns the nearest parent dir whose name ends with ".app" given the
       full path to an executable.  If there is no such parent dir, then
       simply return the dir containing the executable.

       The returned directory may or may not exist.

         GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)

       Takes either a ".app" directory name or the name of an executable
       nested inside a ".app" directory and returns the path to the ".app"
       directory in <bundle_var> and the path to its main executable in
       <executable_var>

         GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)

       Scans the given bundle recursively for all executable files and
       accumulates them into a variable.

         GET_ITEM_KEY(<item> <key_var>)

       Given a file (item) name, generate a key that should be unique
       considering the set of libraries that need copying or fixing up to
       make a bundle standalone.  This is essentially the file name including
       extension with "." replaced by "_"

       This key is used as a prefix for CMake variables so that we can
       associate a set of variables with a given item based on its key.

         CLEAR_BUNDLE_KEYS(<keys_var>)

       Loop over the list of keys, clearing all the variables associated with
       each key.  After the loop, clear the list of keys itself.

       Caller of get_bundle_keys should call clear_bundle_keys when done with
       list of keys.

         SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs>
                               <copyflag>)

       Add a key to the list (if necessary) for the given item.  If added,
       also set all the variables associated with that key.

         GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)

       Loop over all the executable and library files within the bundle (and
       given as extra <libs>) and accumulate a list of keys representing
       them.  Set values associated with each key such that we can loop over
       all of them and copy prerequisite libs into the bundle and then do
       appropriate install_name_tool fixups.

         COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

       Copy a resolved item into the bundle if necessary.  Copy is not
       necessary if the resolved_item is "the same as" the
       resolved_embedded_item.

         COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)

       Copy a resolved framework into the bundle if necessary.  Copy is not
       necessary if the resolved_item is "the same as" the
       resolved_embedded_item.

       By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set.  If you want
       full frameworks embedded in your bundles, set
       BU_COPY_FULL_FRAMEWORK_CONTENTS to ON before calling fixup_bundle.  By
       default, COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework
       dylib itself plus the framework Resources directory.

         FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)

       Get the direct/non-system prerequisites of the resolved embedded item.
       For each prerequisite, change the way it is referenced to the value of
       the _EMBEDDED_ITEM keyed variable for that prerequisite.  (Most likely
       changing to an "@executable_path" style reference.)

       This function requires that the resolved_embedded_item be "inside" the
       bundle already.  In other words, if you pass plugins to fixup_bundle
       as the libs parameter, you should install them or copy them into the
       bundle before calling fixup_bundle.  The "libs" parameter is a list of
       libraries that must be fixed up, but that cannot be determined by
       otool output analysis.  (i.e., plugins)

       Also, change the id of the item being fixed up to its own
       _EMBEDDED_ITEM value.

       Accumulate changes in a local variable and make *one* call to
       install_name_tool at the end of the function with all the changes at
       once.

       If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be
       marked writable before install_name_tool tries to change them.

         VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)

       Verifies that the sum of all prerequisites of all files inside the
       bundle are contained within the bundle or are "system" libraries,
       presumed to exist everywhere.

         VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)

       Verifies that any symlinks found in the bundle point to other files
       that are already also in the bundle...  Anything that points to an
       external file causes this function to fail the verification.

  CMakeAddFortranSubdirectory
       Use MinGW gfortran from VS if a fortran compiler is not found.

       The 'add_fortran_subdirectory' function adds a subdirectory to a
       project that contains a fortran only sub-project.  The module will
       check the current compiler and see if it can support fortran.  If no
       fortran compiler is found and the compiler is MSVC, then this module
       will find the MinGW gfortran.  It will then use an external project to
       build with the MinGW tools.  It will also create imported targets for
       the libraries created.  This will only work if the fortran code is
       built into a dll, so BUILD_SHARED_LIBS is turned on in the project.
       In addition the CMAKE_GNUtoMS option is set to on, so that the MS .lib
       files are created.  Usage is as follows:

         cmake_add_fortran_subdirectory(
          <subdir>                # name of subdirectory
          PROJECT <project_name>  # project name in subdir top CMakeLists.txt
          ARCHIVE_DIR <dir>       # dir where project places .lib files
          RUNTIME_DIR <dir>       # dir where project places .dll files
          LIBRARIES <lib>...      # names of library targets to import
          LINK_LIBRARIES          # link interface libraries for LIBRARIES
           [LINK_LIBS <lib> <dep>...]...
          CMAKE_COMMAND_LINE ...  # extra command line flags to pass to cmake
          NO_EXTERNAL_INSTALL     # skip installation of external project
          )

       Relative paths in ARCHIVE_DIR and RUNTIME_DIR are interpreted with
       respect to the build directory corresponding to the source directory
       in which the function is invoked.

       Limitations:

       NO_EXTERNAL_INSTALL is required for forward compatibility with a
       future version that supports installation of the external project
       binaries during "make install".

  CMakeBackwardCompatibilityCXX
       define a bunch of backwards compatibility variables

         CMAKE_ANSI_CXXFLAGS - flag for ansi c++
         CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
         include(TestForANSIStreamHeaders)
         include(CheckIncludeFileCXX)
         include(TestForSTDNamespace)
         include(TestForANSIForScope)


  CMakeDependentOption
       Macro to provide an option dependent on other options.

       This macro presents an option to the user only if a set of other
       conditions are true.  When the option is not presented a default value
       is used, but any value set by the user is preserved for when the
       option is presented again.  Example invocation:

         CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
                                "USE_BAR;NOT USE_ZOT" OFF)

       If USE_BAR is true and USE_ZOT is false, this provides an option
       called USE_FOO that defaults to ON.  Otherwise, it sets USE_FOO to
       OFF.  If the status of USE_BAR or USE_ZOT ever changes, any value for
       the USE_FOO option is saved so that when the option is re-enabled it
       retains its old value.

  CMakeDetermineVSServicePack
       Determine the Visual Studio service pack of the 'cl' in use.

       The functionality of this module has been superseded by the platform
       variable CMAKE_<LANG>_COMPILER_VERSION that contains the compiler
       version number.

       Usage:

         if(MSVC)
           include(CMakeDetermineVSServicePack)
           DetermineVSServicePack( my_service_pack )
           if( my_service_pack )
             message(STATUS "Detected: ${my_service_pack}")
           endif()
         endif()

       Function DetermineVSServicePack sets the given variable to one of the
       following values or an empty string if unknown:

         vc80, vc80sp1
         vc90, vc90sp1
         vc100, vc100sp1
         vc110, vc110sp1, vc110sp2


  CMakeExpandImportedTargets
        

       CMAKE_EXPAND_IMPORTED_TARGETS(<var> LIBRARIES lib1 lib2...libN

                                            [CONFIGURATION <config>] )

       

       CMAKE_EXPAND_IMPORTED_TARGETS() takes a list of libraries and replaces
       all imported targets contained in this list with their actual file
       paths of the referenced libraries on disk, including the libraries
       from their link interfaces.  If a CONFIGURATION is given, it uses the
       respective configuration of the imported targets if it exists.  If no
       CONFIGURATION is given, it uses the first configuration from
       ${CMAKE_CONFIGURATION_TYPES} if set, otherwise ${CMAKE_BUILD_TYPE}.
       This macro is used by all Check*.cmake files which use try_compile()
       or try_run() and support CMAKE_REQUIRED_LIBRARIES , so that these
       checks support imported targets in CMAKE_REQUIRED_LIBRARIES:

           cmake_expand_imported_targets(expandedLibs LIBRARIES ${CMAKE_REQUIRED_LIBRARIES}
                                                      CONFIGURATION "${CMAKE_TRY_COMPILE_CONFIGURATION}" )


  CMakeFindFrameworks
       helper module to find OSX frameworks

  CMakeFindPackageMode
        

       This file is executed by cmake when invoked with --find-package.  It
       expects that the following variables are set using -D:

          NAME = name of the package
          COMPILER_ID = the CMake compiler ID for which the result is, i.e. GNU/Intel/Clang/MSVC, etc.
          LANGUAGE = language for which the result will be used, i.e. C/CXX/Fortan/ASM
          MODE = EXIST : only check for existence of the given package
                 COMPILE : print the flags needed for compiling an object file which uses the given package
                 LINK : print the flags needed for linking when using the given package
          QUIET = if TRUE, don't print anything


  CMakeForceCompiler
        

       This module defines macros intended for use by cross-compiling
       toolchain files when CMake is not able to automatically detect the
       compiler identification.

       Macro CMAKE_FORCE_C_COMPILER has the following signature:

          CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)

       It sets CMAKE_C_COMPILER to the given compiler and the cmake internal
       variable CMAKE_C_COMPILER_ID to the given compiler-id.  It also
       bypasses the check for working compiler and basic compiler information
       tests.

       Macro CMAKE_FORCE_CXX_COMPILER has the following signature:

          CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)

       It sets CMAKE_CXX_COMPILER to the given compiler and the cmake
       internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id.  It
       also bypasses the check for working compiler and basic compiler
       information tests.

       Macro CMAKE_FORCE_Fortran_COMPILER has the following signature:

          CMAKE_FORCE_Fortran_COMPILER(<compiler> <compiler-id>)

       It sets CMAKE_Fortran_COMPILER to the given compiler and the cmake
       internal variable CMAKE_Fortran_COMPILER_ID to the given compiler-id.
       It also bypasses the check for working compiler and basic compiler
       information tests.

       So a simple toolchain file could look like this:

          include (CMakeForceCompiler)
          set(CMAKE_SYSTEM_NAME Generic)
          CMAKE_FORCE_C_COMPILER   (chc12 MetrowerksHicross)
          CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)


  CMakeGraphVizOptions
       The builtin graphviz support of CMake.

       CMake can generate graphviz files, showing the dependencies between
       the targets in a project and also external libraries which are linked
       against.  When CMake is run with the --graphiz=foo option, it will
       produce

           * a foo.dot file showing all dependencies in the project
           * a foo.dot.<target> file for each target, file showing on which other targets the respective target depends
           * a foo.dot.<target>.dependers file, showing which other targets depend on the respective target

       

       This can result in huge graphs.  Using the file
       CMakeGraphVizOptions.cmake the look and content of the generated
       graphs can be influenced.  This file is searched first in
       ${CMAKE_BINARY_DIR} and then in ${CMAKE_SOURCE_DIR}.  If found, it is
       read and the variables set in it are used to adjust options for the
       generated graphviz files.

         GRAPHVIZ_GRAPH_TYPE - The graph type
            Mandatory : NO
            Default   : "digraph"
         GRAPHVIZ_GRAPH_NAME - The graph name.
            Mandatory : NO
            Default   : "GG"
         GRAPHVIZ_GRAPH_HEADER - The header written at the top of the graphviz file.
            Mandatory : NO
            Default   : "node [n  fontsize = "12"];"
         GRAPHVIZ_NODE_PREFIX - The prefix for each node in the graphviz file.
            Mandatory : NO
            Default   : "node"
         GRAPHVIZ_EXECUTABLES - Set this to FALSE to exclude executables from the generated graphs.
            Mandatory : NO
            Default   : TRUE
         GRAPHVIZ_STATIC_LIBS - Set this to FALSE to exclude static libraries from the generated graphs.
            Mandatory : NO
            Default   : TRUE
         GRAPHVIZ_SHARED_LIBS - Set this to FALSE to exclude shared libraries from the generated graphs.
            Mandatory : NO
            Default   : TRUE
         GRAPHVIZ_MODULE_LIBS - Set this to FALSE to exclude static libraries from the generated graphs.
            Mandatory : NO
            Default   : TRUE
         GRAPHVIZ_EXTERNAL_LIBS - Set this to FALSE to exclude external libraries from the generated graphs.
            Mandatory : NO
            Default   : TRUE
         GRAPHVIZ_IGNORE_TARGETS - A list of regular expressions for ignoring targets.
            Mandatory : NO
            Default   : empty


  CMakePackageConfigHelpers
       CONFIGURE_PACKAGE_CONFIG_FILE(), WRITE_BASIC_PACKAGE_VERSION_FILE()

       

           CONFIGURE_PACKAGE_CONFIG_FILE(<input> <output> INSTALL_DESTINATION <path>
                                                          [PATH_VARS <var1> <var2> ... <varN>]
                                                          [NO_SET_AND_CHECK_MACRO]
                                                          [NO_CHECK_REQUIRED_COMPONENTS_MACRO])

       

       CONFIGURE_PACKAGE_CONFIG_FILE() should be used instead of the plain
       configure_file() command when creating the <Name>Config.cmake or
       <Name>-config.cmake file for installing a project or library.  It
       helps making the resulting package relocatable by avoiding hardcoded
       paths in the installed Config.cmake file.

       In a FooConfig.cmake file there may be code like this to make the
       install destinations know to the using project:

          set(FOO_INCLUDE_DIR   "@CMAKE_INSTALL_FULL_INCLUDEDIR@" )
          set(FOO_DATA_DIR   "@CMAKE_INSTALL_PREFIX@/@RELATIVE_DATA_INSTALL_DIR@" )
          set(FOO_ICONS_DIR   "@CMAKE_INSTALL_PREFIX@/share/icons" )
          ...logic to determine installedPrefix from the own location...
          set(FOO_CONFIG_DIR  "${installedPrefix}/@CONFIG_INSTALL_DIR@" )

       All 4 options shown above are not sufficient, since the first 3
       hardcode the absolute directory locations, and the 4th case works only
       if the logic to determine the installedPrefix is correct, and if
       CONFIG_INSTALL_DIR contains a relative path, which in general cannot
       be guaranteed.  This has the effect that the resulting FooConfig.cmake
       file would work poorly under Windows and OSX, where users are used to
       choose the install location of a binary package at install time,
       independent from how CMAKE_INSTALL_PREFIX was set at build/cmake time.

       Using CONFIGURE_PACKAGE_CONFIG_FILE() helps.  If used correctly, it
       makes the resulting FooConfig.cmake file relocatable.  Usage:

          1. write a FooConfig.cmake.in file as you are used to
          2. insert a line containing only the string "@PACKAGE_INIT@"
          3. instead of set(FOO_DIR "@SOME_INSTALL_DIR@"), use set(FOO_DIR "@PACKAGE_SOME_INSTALL_DIR@")
             (this must be after the @PACKAGE_INIT@ line)
          4. instead of using the normal configure_file(), use CONFIGURE_PACKAGE_CONFIG_FILE()

       

       The <input> and <output> arguments are the input and output file, the
       same way as in configure_file().

       The <path> given to INSTALL_DESTINATION must be the destination where
       the FooConfig.cmake file will be installed to.  This can either be a
       relative or absolute path, both work.

       The variables <var1> to <varN> given as PATH_VARS are the variables
       which contain install destinations.  For each of them the macro will
       create a helper variable PACKAGE_<var...>.  These helper variables
       must be used in the FooConfig.cmake.in file for setting the installed
       location.  They are calculated by CONFIGURE_PACKAGE_CONFIG_FILE() so
       that they are always relative to the installed location of the
       package.  This works both for relative and also for absolute
       locations.  For absolute locations it works only if the absolute
       location is a subdirectory of CMAKE_INSTALL_PREFIX.

       By default configure_package_config_file() also generates two helper
       macros, set_and_check() and check_required_components() into the
       FooConfig.cmake file.

       set_and_check() should be used instead of the normal set() command for
       setting directories and file locations.  Additionally to setting the
       variable it also checks that the referenced file or directory actually
       exists and fails with a FATAL_ERROR otherwise.  This makes sure that
       the created FooConfig.cmake file does not contain wrong references.
       When using the NO_SET_AND_CHECK_MACRO, this macro is not generated
       into the FooConfig.cmake file.

       check_required_components(<package_name>) should be called at the end
       of the FooConfig.cmake file if the package supports components.  This
       macro checks whether all requested, non-optional components have been
       found, and if this is not the case, sets the Foo_FOUND variable to
       FALSE, so that the package is considered to be not found.  It does
       that by testing the Foo_<Component>_FOUND variables for all requested
       required components.  When using the NO_CHECK_REQUIRED_COMPONENTS
       option, this macro is not generated into the FooConfig.cmake file.

       For an example see below the documentation for
       WRITE_BASIC_PACKAGE_VERSION_FILE().

       

         WRITE_BASIC_PACKAGE_VERSION_FILE( filename VERSION major.minor.patch COMPATIBILITY (AnyNewerVersion|SameMajorVersion|ExactVersion) )

       

       Writes a file for use as <package>ConfigVersion.cmake file to
       <filename>.  See the documentation of find_package() for details on
       this.

           filename is the output filename, it should be in the build tree.
           major.minor.patch is the version number of the project to be installed

       The COMPATIBILITY mode AnyNewerVersion means that the installed
       package version will be considered compatible if it is newer or
       exactly the same as the requested version.  This mode should be used
       for packages which are fully backward compatible, also across major
       versions.  If SameMajorVersion is used instead, then the behaviour
       differs from AnyNewerVersion in that the major version number must be
       the same as requested, e.g.  version 2.0 will not be considered
       compatible if 1.0 is requested.  This mode should be used for packages
       which guarantee backward compatibility within the same major version.
       If ExactVersion is used, then the package is only considered
       compatible if the requested version matches exactly its own version
       number (not considering the tweak version).  For example, version
       1.2.3 of a package is only considered compatible to requested version
       1.2.3.  This mode is for packages without compatibility guarantees.
       If your project has more elaborated version matching rules, you will
       need to write your own custom ConfigVersion.cmake file instead of
       using this macro.

       Internally, this macro executes configure_file() to create the
       resulting version file.  Depending on the COMPATIBLITY, either the
       file BasicConfigVersion-SameMajorVersion.cmake.in or
       BasicConfigVersion-AnyNewerVersion.cmake.in is used.  Please note that
       these two files are internal to CMake and you should not call
       configure_file() on them yourself, but they can be used as starting
       point to create more sophisticted custom ConfigVersion.cmake files.

       

       Example using both configure_package_config_file() and
       write_basic_package_version_file(): CMakeLists.txt:

          set(INCLUDE_INSTALL_DIR include/ ... CACHE )
          set(LIB_INSTALL_DIR lib/ ... CACHE )
          set(SYSCONFIG_INSTALL_DIR etc/foo/ ... CACHE )
          ...
          include(CMakePackageConfigHelpers)
          configure_package_config_file(FooConfig.cmake.in ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake
                                        INSTALL_DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake
                                        PATH_VARS INCLUDE_INSTALL_DIR SYSCONFIG_INSTALL_DIR)
          write_basic_package_version_file(${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake
                                           VERSION 1.2.3
                                           COMPATIBILITY SameMajorVersion )
          install(FILES ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake ${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake
                  DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake )

       

       With a FooConfig.cmake.in:

          set(FOO_VERSION x.y.z)
          ...
          @PACKAGE_INIT@
          ...
          set_and_check(FOO_INCLUDE_DIR "@PACKAGE_INCLUDE_INSTALL_DIR@")
          set_and_check(FOO_SYSCONFIG_DIR "@PACKAGE_SYSCONFIG_INSTALL_DIR@")

       

          check_required_components(Foo)


  CMakeParseArguments
        

       CMAKE_PARSE_ARGUMENTS(<prefix> <options> <one_value_keywords>
       <multi_value_keywords> args...)

       CMAKE_PARSE_ARGUMENTS() is intended to be used in macros or functions
       for parsing the arguments given to that macro or function.  It
       processes the arguments and defines a set of variables which hold the
       values of the respective options.

       The <options> argument contains all options for the respective macro,
       i.e.  keywords which can be used when calling the macro without any
       value following, like e.g.  the OPTIONAL keyword of the install()
       command.

       The <one_value_keywords> argument contains all keywords for this macro
       which are followed by one value, like e.g.  DESTINATION keyword of the
       install() command.

       The <multi_value_keywords> argument contains all keywords for this
       macro which can be followed by more than one value, like e.g.  the
       TARGETS or FILES keywords of the install() command.

       When done, CMAKE_PARSE_ARGUMENTS() will have defined for each of the
       keywords listed in <options>, <one_value_keywords> and
       <multi_value_keywords> a variable composed of the given <prefix>
       followed by "_" and the name of the respective keyword.  These
       variables will then hold the respective value from the argument list.
       For the <options> keywords this will be TRUE or FALSE.

       All remaining arguments are collected in a variable
       <prefix>_UNPARSED_ARGUMENTS, this can be checked afterwards to see
       whether your macro was called with unrecognized parameters.

       As an example here a my_install() macro, which takes similar arguments
       as the real install() command:

          function(MY_INSTALL)
            set(options OPTIONAL FAST)
            set(oneValueArgs DESTINATION RENAME)
            set(multiValueArgs TARGETS CONFIGURATIONS)
            cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN} )
            ...

       

       Assume my_install() has been called like this:

          my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub)

       

       After the cmake_parse_arguments() call the macro will have set the
       following variables:

          MY_INSTALL_OPTIONAL = TRUE
          MY_INSTALL_FAST = FALSE (this option was not used when calling my_install()
          MY_INSTALL_DESTINATION = "bin"
          MY_INSTALL_RENAME = "" (was not used)
          MY_INSTALL_TARGETS = "foo;bar"
          MY_INSTALL_CONFIGURATIONS = "" (was not used)
          MY_INSTALL_UNPARSED_ARGUMENTS = "blub" (no value expected after "OPTIONAL"

       

       You can then continue and process these variables.

       Keywords terminate lists of values, e.g.  if directly after a
       one_value_keyword another recognized keyword follows, this is
       interpreted as the beginning of the new option.  E.g.
       my_install(TARGETS foo DESTINATION OPTIONAL) would result in
       MY_INSTALL_DESTINATION set to "OPTIONAL", but MY_INSTALL_DESTINATION
       would be empty and MY_INSTALL_OPTIONAL would be set to TRUE therefor.

  CMakePrintHelpers
       Convenience macros for printing properties and variables, useful e.g.
       for debugging.

       

       

       CMAKE_PRINT_PROPERTIES([TARGETS target1 ..  targetN]

                               [SOURCES source1 .. sourceN]
                               [DIRECTORIES dir1 .. dirN]
                               [TESTS test1 .. testN]
                               [CACHE_ENTRIES entry1 .. entryN]
                               PROPERTIES prop1 .. propN )

       

       This macro prints the values of the properties of the given targets,
       source files, directories, tests or cache entries.  Exactly one of the
       scope keywords must be used.  Example:

          cmake_print_properties(TARGETS foo bar PROPERTIES LOCATION INTERFACE_INCLUDE_DIRS)

       This will print the LOCATION and INTERFACE_INCLUDE_DIRS properties for
       both targets foo and bar.

       

       CMAKE_PRINT_VARIABLES(var1 var2 ..  varN)

       This macro will print the name of each variable followed by its value.
       Example:

          cmake_print_variables(CMAKE_C_COMPILER CMAKE_MAJOR_VERSION THIS_ONE_DOES_NOT_EXIST)

       Gives:

          -- CMAKE_C_COMPILER="/usr/bin/gcc" ; CMAKE_MAJOR_VERSION="2" ; THIS_ONE_DOES_NOT_EXIST=""


  CMakePrintSystemInformation
       print system information

       This file can be used for diagnostic purposes just include it in a
       project to see various internal CMake variables.

  CMakePushCheckState
        

       This module defines three macros: CMAKE_PUSH_CHECK_STATE()
       CMAKE_POP_CHECK_STATE() and CMAKE_RESET_CHECK_STATE() These macros can
       be used to save, restore and reset (i.e., clear contents) the state of
       the variables CMAKE_REQUIRED_FLAGS, CMAKE_REQUIRED_DEFINITIONS,
       CMAKE_REQUIRED_LIBRARIES and CMAKE_REQUIRED_INCLUDES used by the
       various Check-files coming with CMake, like e.g.
       check_function_exists() etc.  The variable contents are pushed on a
       stack, pushing multiple times is supported.  This is useful e.g.  when
       executing such tests in a Find-module, where they have to be set, but
       after the Find-module has been executed they should have the same
       value as they had before.

       CMAKE_PUSH_CHECK_STATE() macro receives optional argument RESET.
       Whether it's specified, CMAKE_PUSH_CHECK_STATE() will set all
       CMAKE_REQUIRED_* variables to empty values, same as
       CMAKE_RESET_CHECK_STATE() call will do.

       Usage:

          cmake_push_check_state(RESET)
          set(CMAKE_REQUIRED_DEFINITIONS -DSOME_MORE_DEF)
          check_function_exists(...)
          cmake_reset_check_state()
          set(CMAKE_REQUIRED_DEFINITIONS -DANOTHER_DEF)
          check_function_exists(...)
          cmake_pop_check_state()


  CMakeVerifyManifest
        

       CMakeVerifyManifest.cmake

       This script is used to verify that embeded manifests and side by side
       manifests for a project match.  To run this script, cd to a directory
       and run the script with cmake -P.  On the command line you can pass in
       versions that are OK even if not found in the .manifest files.  For
       example, cmake -Dallow_versions=8.0.50608.0
       -PCmakeVerifyManifest.cmake could be used to allow an embeded manifest
       of 8.0.50608.0 to be used in a project even if that version was not
       found in the .manifest file.

  CPack
       Build binary and source package installers.

       The CPack module generates binary and source installers in a variety
       of formats using the cpack program.  Inclusion of the CPack module
       adds two new targets to the resulting makefiles, package and
       package_source, which build the binary and source installers,
       respectively.  The generated binary installers contain everything
       installed via CMake's INSTALL command (and the deprecated
       INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).

       For certain kinds of binary installers (including the graphical
       installers on Mac OS X and Windows), CPack generates installers that
       allow users to select individual application components to install.
       See CPackComponent module for that.

       The CPACK_GENERATOR variable has different meanings in different
       contexts.  In your CMakeLists.txt file, CPACK_GENERATOR is a *list of
       generators*: when run with no other arguments, CPack will iterate over
       that list and produce one package for each generator.  In a
       CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERATOR is a *string naming
       a single generator*.  If you need per-cpack- generator logic to
       control *other* cpack settings, then you need a
       CPACK_PROJECT_CONFIG_FILE.

       The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE.
       See the top level file CMakeCPackOptions.cmake.in for an example.

       If set, the CPACK_PROJECT_CONFIG_FILE is included automatically on a
       per-generator basis.  It only need contain overrides.

       Here's how it works:

         - cpack runs
         - it includes CPackConfig.cmake
         - it iterates over the generators listed in that file's
           CPACK_GENERATOR list variable (unless told to use just a
           specific one via -G on the command line...)

       

         - foreach generator, it then
           - sets CPACK_GENERATOR to the one currently being iterated
           - includes the CPACK_PROJECT_CONFIG_FILE
           - produces the package for that generator

       

       This is the key: For each generator listed in CPACK_GENERATOR in
       CPackConfig.cmake, cpack will *reset* CPACK_GENERATOR internally to
       *the one currently being used* and then include the
       CPACK_PROJECT_CONFIG_FILE.

       Before including this CPack module in your CMakeLists.txt file, there
       are a variety of variables that can be set to customize the resulting
       installers.  The most commonly-used variables are:

         CPACK_PACKAGE_NAME - The name of the package (or application). If
         not specified, defaults to the project name.

       

         CPACK_PACKAGE_VENDOR - The name of the package vendor. (e.g.,
         "Kitware").

       

         CPACK_PACKAGE_DIRECTORY - The directory in which CPack is doing its
         packaging. If it is not set then this will default (internally) to the
         build dir. This variable may be defined in CPack config file or from
         the cpack command line option "-B". If set the command line option
         override the value found in the config file.

       

         CPACK_PACKAGE_VERSION_MAJOR - Package major Version

       

         CPACK_PACKAGE_VERSION_MINOR - Package minor Version

       

         CPACK_PACKAGE_VERSION_PATCH - Package patch Version

       

         CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
         project. Used, for example, the introduction screen of a
         CPack-generated Windows installer to describe the project.

       

         CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
         project (only a few words).

       

         CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
         not including the extension. For example, cmake-2.6.1-Linux-i686.
         The default value is

       

         ${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}.

       

         CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
         target system. This may be used by some CPack generators
         like NSIS to create an installation directory e.g., "CMake 2.5"
         below the installation prefix. All installed element will be
         put inside this directory.

       

          CPACK_PACKAGE_ICON - A branding image that will be displayed inside
          the installer (used by GUI installers).

       

         CPACK_PROJECT_CONFIG_FILE - CPack-time project CPack configuration
         file. This file included at cpack time, once per
         generator after CPack has set CPACK_GENERATOR to the actual generator
         being used. It allows per-generator setting of CPACK_* variables at
         cpack time.

       

         CPACK_RESOURCE_FILE_LICENSE - License to be embedded in the installer. It
         will typically be displayed to the user by the produced installer
         (often with an explicit "Accept" button, for graphical installers)
         prior to installation. This license file is NOT added to installed
         file but is used by some CPack generators like NSIS. If you want
         to install a license file (may be the same as this one)
         along with your project you must add an appropriate CMake INSTALL
         command in your CMakeLists.txt.

       

         CPACK_RESOURCE_FILE_README - ReadMe file to be embedded in the installer. It
         typically describes in some detail the purpose of the project
         during the installation. Not all CPack generators uses
         this file.

       

         CPACK_RESOURCE_FILE_WELCOME - Welcome file to be embedded in the
         installer. It welcomes users to this installer.
         Typically used in the graphical installers on Windows and Mac OS X.

       

         CPACK_MONOLITHIC_INSTALL - Disables the component-based
         installation mechanism. When set the component specification is ignored
         and all installed items are put in a single "MONOLITHIC" package.
         Some CPack generators do monolithic packaging by default and
         may be asked to do component packaging by setting
         CPACK_<GENNAME>_COMPONENT_INSTALL to 1/TRUE.

       

         CPACK_GENERATOR - List of CPack generators to use. If not
         specified, CPack will create a set of options CPACK_BINARY_<GENNAME> (e.g.,
         CPACK_BINARY_NSIS) allowing the user to enable/disable individual
         generators. This variable may be used on the command line
         as well as in:

       

           cpack -D CPACK_GENERATOR="ZIP;TGZ" /path/to/build/tree

       

         CPACK_OUTPUT_CONFIG_FILE - The name of the CPack binary configuration
         file. This file is the CPack configuration generated by the CPack module
         for binary installers. Defaults to CPackConfig.cmake.

       

         CPACK_PACKAGE_EXECUTABLES - Lists each of the executables and associated
         text label to be used to create Start Menu shortcuts. For example,
         setting this to the list ccmake;CMake will
         create a shortcut named "CMake" that will execute the installed
         executable ccmake. Not all CPack generators use it (at least NSIS and
         OSXX11 do).

       

         CPACK_STRIP_FILES - List of files to be stripped. Starting with
         CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
         enables stripping of all files (a list of files evaluates to TRUE
         in CMake, so this change is compatible).

       

       The following CPack variables are specific to source packages, and
       will not affect binary packages:

         CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package. For
         example cmake-2.6.1.

       

         CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
         will be stripped. Starting with CMake 2.6.0
         CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
         stripping of all files (a list of files evaluates to TRUE in CMake,
         so this change is compatible).

       

         CPACK_SOURCE_GENERATOR - List of generators used for the source
         packages. As with CPACK_GENERATOR, if this is not specified then
         CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
         allowing users to select which packages will be generated.

       

         CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack source
         configuration file. This file is the CPack configuration generated by the
         CPack module for source installers. Defaults to CPackSourceConfig.cmake.

       

         CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
         that won't be packaged when building a source package. This is a
         list of regular expression patterns (that must be properly escaped),
         e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*

       

       The following variables are for advanced uses of CPack:

         CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
         project is CMake project. Defaults to the value of CMAKE_GENERATOR
         few users will want to change this setting.

       

         CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
         what project to install. The four values are: Build directory,
         Project Name, Project Component, Directory. If omitted, CPack will
         build an installer that installers everything.

       

         CPACK_SYSTEM_NAME - System name, defaults to the value of
         ${CMAKE_SYSTEM_NAME}.

       

         CPACK_PACKAGE_VERSION - Package full version, used internally. By
         default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
         CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.

       

         CPACK_TOPLEVEL_TAG - Directory for the installed files.

       

         CPACK_INSTALL_COMMANDS - Extra commands to install components.

       

         CPACK_INSTALLED_DIRECTORIES - Extra directories to install.

       

          CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
          installing this project. This is only used by installer for Windows.
          The default value is based on the installation directory.
          CPACK_CREATE_DESKTOP_LINKS - List of desktop links to create.

       


  CPackBundle
       CPack Bundle generator (Mac OS X) specific options

       

       Installers built on Mac OS X using the Bundle generator use the
       aforementioned DragNDrop (CPACK_DMG_xxx) variables, plus the following
       Bundle-specific parameters (CPACK_BUNDLE_xxx).

         CPACK_BUNDLE_NAME - The name of the generated bundle. This
         appears in the OSX finder as the bundle name. Required.

       

         CPACK_BUNDLE_PLIST - Path to an OSX plist file that will be used
         for the generated bundle. This assumes that the caller has generated
         or specified their own Info.plist file. Required.

       

         CPACK_BUNDLE_ICON - Path to an OSX icon file that will be used as
         the icon for the generated bundle. This is the icon that appears in the
         OSX finder for the bundle, and in the OSX dock when the bundle is opened.
         Required.

       

         CPACK_BUNDLE_STARTUP_COMMAND - Path to a startup script. This is a path to
         an executable or script that will be run whenever an end-user double-clicks
         the generated bundle in the OSX Finder. Optional.


  CPackComponent
       Build binary and source package installers

       

       The CPackComponent module is the module which handles the component
       part of CPack.  See CPack module for general information about CPack.

       For certain kinds of binary installers (including the graphical
       installers on Mac OS X and Windows), CPack generates installers that
       allow users to select individual application components to install.
       The contents of each of the components are identified by the COMPONENT
       argument of CMake's INSTALL command.  These components can be
       annotated with user-friendly names and descriptions, inter-component
       dependencies, etc., and grouped in various ways to customize the
       resulting installer.  See the cpack_add_* commands, described below,
       for more information about component-specific installations.

       Component-specific installation allows users to select specific sets
       of components to install during the install process.  Installation
       components are identified by the COMPONENT argument of CMake's INSTALL
       commands, and should be further described by the following CPack
       commands:

         CPACK_COMPONENTS_ALL - The list of component to install.

       

       The default value of this variable is computed by CPack and contains
       all components defined by the project.  The user may set it to only
       include the specified components.

         CPACK_<GENNAME>_COMPONENT_INSTALL - Enable/Disable component install for
         CPack generator <GENNAME>.

       

       Each CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has a
       legacy default behavior.  e.g.  RPM builds monolithic whereas NSIS
       builds component.  One can change the default behavior by setting this
       variable to 0/1 or OFF/ON.

         CPACK_COMPONENTS_GROUPING - Specify how components are grouped for multi-package
         component-aware CPack generators.

       

       Some generators like RPM or ARCHIVE family (TGZ, ZIP, ...) generates
       several packages files when asked for component packaging.  They group
       the component differently depending on the value of this variable:

         - ONE_PER_GROUP (default): creates one package file per component group
         - ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component
         - IGNORE : creates one package per component, i.e. IGNORE component group

       One can specify different grouping for different CPack generator by
       using a CPACK_PROJECT_CONFIG_FILE.

         CPACK_COMPONENT_<compName>_DISPLAY_NAME - The name to be displayed for a component.
         CPACK_COMPONENT_<compName>_DESCRIPTION - The description of a component.
         CPACK_COMPONENT_<compName>_GROUP - The group of a component.
         CPACK_COMPONENT_<compName>_DEPENDS - The dependencies (list of components)
         on which this component depends.
         CPACK_COMPONENT_<compName>_REQUIRED - True is this component is required.

       cpack_add_component - Describes a CPack installation component named
       by the COMPONENT argument to a CMake INSTALL command.

         cpack_add_component(compname
                             [DISPLAY_NAME name]
                             [DESCRIPTION description]
                             [HIDDEN | REQUIRED | DISABLED ]
                             [GROUP group]
                             [DEPENDS comp1 comp2 ... ]
                             [INSTALL_TYPES type1 type2 ... ]
                             [DOWNLOADED]
                             [ARCHIVE_FILE filename])

       

       The cmake_add_component command describes an installation component,
       which the user can opt to install or remove as part of the graphical
       installation process.  compname is the name of the component, as
       provided to the COMPONENT argument of one or more CMake INSTALL
       commands.

       DISPLAY_NAME is the displayed name of the component, used in graphical
       installers to display the component name.  This value can be any
       string.

       DESCRIPTION is an extended description of the component, used in
       graphical installers to give the user additional information about the
       component.  Descriptions can span multiple lines using "\n" as the
       line separator.  Typically, these descriptions should be no more than
       a few lines long.

       HIDDEN indicates that this component will be hidden in the graphical
       installer, so that the user cannot directly change whether it is
       installed or not.

       REQUIRED indicates that this component is required, and therefore will
       always be installed.  It will be visible in the graphical installer,
       but it cannot be unselected.  (Typically, required components are
       shown greyed out).

       DISABLED indicates that this component should be disabled (unselected)
       by default.  The user is free to select this component for
       installation, unless it is also HIDDEN.

       DEPENDS lists the components on which this component depends.  If this
       component is selected, then each of the components listed must also be
       selected.  The dependency information is encoded within the installer
       itself, so that users cannot install inconsistent sets of components.

       GROUP names the component group of which this component is a part.  If
       not provided, the component will be a standalone component, not part
       of any component group.  Component groups are described with the
       cpack_add_component_group command, detailed below.

       INSTALL_TYPES lists the installation types of which this component is
       a part.  When one of these installations types is selected, this
       component will automatically be selected.  Installation types are
       described with the cpack_add_install_type command, detailed below.

       DOWNLOADED indicates that this component should be downloaded
       on-the-fly by the installer, rather than packaged in with the
       installer itself.  For more information, see the
       cpack_configure_downloads command.

       ARCHIVE_FILE provides a name for the archive file created by CPack to
       be used for downloaded components.  If not supplied, CPack will create
       a file with some name based on CPACK_PACKAGE_FILE_NAME and the name of
       the component.  See cpack_configure_downloads for more information.

       cpack_add_component_group - Describes a group of related CPack
       installation components.

         cpack_add_component_group(groupname
                                  [DISPLAY_NAME name]
                                  [DESCRIPTION description]
                                  [PARENT_GROUP parent]
                                  [EXPANDED]
                                  [BOLD_TITLE])

       

       The cpack_add_component_group describes a group of installation
       components, which will be placed together within the listing of
       options.  Typically, component groups allow the user to
       select/deselect all of the components within a single group via a
       single group-level option.  Use component groups to reduce the
       complexity of installers with many options.  groupname is an arbitrary
       name used to identify the group in the GROUP argument of the
       cpack_add_component command, which is used to place a component in a
       group.  The name of the group must not conflict with the name of any
       component.

       DISPLAY_NAME is the displayed name of the component group, used in
       graphical installers to display the component group name.  This value
       can be any string.

       DESCRIPTION is an extended description of the component group, used in
       graphical installers to give the user additional information about the
       components within that group.  Descriptions can span multiple lines
       using "\n" as the line separator.  Typically, these descriptions
       should be no more than a few lines long.

       PARENT_GROUP, if supplied, names the parent group of this group.
       Parent groups are used to establish a hierarchy of groups, providing
       an arbitrary hierarchy of groups.

       EXPANDED indicates that, by default, the group should show up as
       "expanded", so that the user immediately sees all of the components
       within the group.  Otherwise, the group will initially show up as a
       single entry.

       BOLD_TITLE indicates that the group title should appear in bold, to
       call the user's attention to the group.

       cpack_add_install_type - Add a new installation type containing a set
       of predefined component selections to the graphical installer.

         cpack_add_install_type(typename
                                [DISPLAY_NAME name])

       

       The cpack_add_install_type command identifies a set of preselected
       components that represents a common use case for an application.  For
       example, a "Developer" install type might include an application along
       with its header and library files, while an "End user" install type
       might just include the application's executable.  Each component
       identifies itself with one or more install types via the INSTALL_TYPES
       argument to cpack_add_component.

       DISPLAY_NAME is the displayed name of the install type, which will
       typically show up in a drop-down box within a graphical installer.
       This value can be any string.

       cpack_configure_downloads - Configure CPack to download selected
       components on-the-fly as part of the installation process.

         cpack_configure_downloads(site
                                   [UPLOAD_DIRECTORY dirname]
                                   [ALL]
                                   [ADD_REMOVE|NO_ADD_REMOVE])

       

       The cpack_configure_downloads command configures installation-time
       downloads of selected components.  For each downloadable component,
       CPack will create an archive containing the contents of that
       component, which should be uploaded to the given site.  When the user
       selects that component for installation, the installer will download
       and extract the component in place.  This feature is useful for
       creating small installers that only download the requested components,
       saving bandwidth.  Additionally, the installers are small enough that
       they will be installed as part of the normal installation process, and
       the "Change" button in Windows Add/Remove Programs control panel will
       allow one to add or remove parts of the application after the original
       installation.  On Windows, the downloaded-components functionality
       requires the ZipDLL plug-in for NSIS, available at:

         http://nsis.sourceforge.net/ZipDLL_plug-in

       

       On Mac OS X, installers that download components on-the-fly can only
       be built and installed on system using Mac OS X 10.5 or later.

       The site argument is a URL where the archives for downloadable
       components will reside, e.g.,
       http://www.cmake.org/files/2.6.1/installer/ All of the archives
       produced by CPack should be uploaded to that location.

       UPLOAD_DIRECTORY is the local directory where CPack will create the
       various archives for each of the components.  The contents of this
       directory should be uploaded to a location accessible by the URL given
       in the site argument.  If omitted, CPack will use the directory
       CPackUploads inside the CMake binary directory to store the generated
       archives.

       The ALL flag indicates that all components be downloaded.  Otherwise,
       only those components explicitly marked as DOWNLOADED or that have a
       specified ARCHIVE_FILE will be downloaded.  Additionally, the ALL
       option implies ADD_REMOVE (unless NO_ADD_REMOVE is specified).

       ADD_REMOVE indicates that CPack should install a copy of the installer
       that can be called from Windows' Add/Remove Programs dialog (via the
       "Modify" button) to change the set of installed components.
       NO_ADD_REMOVE turns off this behavior.  This option is ignored on Mac
       OS X.

  CPackCygwin
       Cygwin CPack generator (Cygwin).

       The following variable is specific to installers build on and/or for
       Cygwin:

          CPACK_CYGWIN_PATCH_NUMBER - The Cygwin patch number.
          FIXME: This documentation is incomplete.
          CPACK_CYGWIN_PATCH_FILE - The Cygwin patch file.
          FIXME: This documentation is incomplete.
          CPACK_CYGWIN_BUILD_SCRIPT - The Cygwin build script.
          FIXME: This documentation is incomplete.


  CPackDMG
       DragNDrop CPack generator (Mac OS X).

       The following variables are specific to the DragNDrop installers built
       on Mac OS X:

         CPACK_DMG_VOLUME_NAME - The volume name of the generated disk
         image. Defaults to CPACK_PACKAGE_FILE_NAME.

       

         CPACK_DMG_FORMAT - The disk image format. Common values are UDRO
         (UDIF read-only), UDZO (UDIF zlib-compressed) or UDBZ (UDIF
         bzip2-compressed). Refer to hdiutil(1) for more information on
         other available formats.

       

         CPACK_DMG_DS_STORE - Path to a custom DS_Store file. This .DS_Store
         file e.g. can be used to specify the Finder window
         position/geometry and layout (such as hidden toolbars, placement of the
         icons etc.). This file has to be generated by the Finder (either manually or
         through OSA-script) using a normal folder from which the .DS_Store
         file can then be extracted.

       

         CPACK_DMG_BACKGROUND_IMAGE - Path to a background image file. This
         file will be used as the background for the Finder Window when the disk
         image is opened.  By default no background image is set. The background
         image is applied after applying the custom .DS_Store file.

       

         CPACK_COMMAND_HDIUTIL - Path to the hdiutil(1) command used to
         operate on disk image files on Mac OS X. This variable can be used
         to override the automatically detected command (or specify its
         location if the auto-detection fails to find it.)

       

         CPACK_COMMAND_SETFILE - Path to the SetFile(1) command used to set
         extended attributes on files and directories on Mac OS X. This
         variable can be used to override the automatically detected
         command (or specify its location if the auto-detection fails to
         find it.)

       

         CPACK_COMMAND_REZ - Path to the Rez(1) command used to compile
         resources on Mac OS X. This variable can be used to override the
         automatically detected command (or specify its location if the
         auto-detection fails to find it.)


  CPackDeb
       The builtin (binary) CPack Deb generator (Unix only)

       CPackDeb may be used to create Deb package using CPack.  CPackDeb is a
       CPack generator thus it uses the CPACK_XXX variables used by CPack :
       http://www.cmake.org/Wiki/CMake:CPackConfiguration.  CPackDeb
       generator should work on any linux host but it will produce better deb
       package when Debian specific tools 'dpkg-xxx' are usable on the build
       system.

       CPackDeb has specific features which are controlled by the specifics
       CPACK_DEBIAN_XXX variables.You'll find a detailed usage on the wiki:

         http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#DEB_.28UNIX_only.29

  CPackNSIS
       CPack NSIS generator specific options

       

       The following variables are specific to the graphical installers built
       on Windows using the Nullsoft Installation System.

          CPACK_NSIS_INSTALL_ROOT - The default installation directory presented
          to the end user by the NSIS installer is under this root dir. The full
          directory presented to the end user is:
          ${CPACK_NSIS_INSTALL_ROOT}/${CPACK_PACKAGE_INSTALL_DIRECTORY}

       

          CPACK_NSIS_MUI_ICON - An icon filename.
          The name of a *.ico file used as the main icon for the generated
          install program.

       

          CPACK_NSIS_MUI_UNIICON - An icon filename.
          The name of a *.ico file used as the main icon for the generated
          uninstall program.

       

          CPACK_NSIS_INSTALLER_MUI_ICON_CODE - undocumented.

       

          CPACK_NSIS_EXTRA_PREINSTALL_COMMANDS - Extra NSIS commands that
          will be added to the beginning of the install Section, before your
          install tree is available on the target system.

       

          CPACK_NSIS_EXTRA_INSTALL_COMMANDS - Extra NSIS commands that
          will be added to the end of the install Section, after your
          install tree is available on the target system.

       

          CPACK_NSIS_EXTRA_UNINSTALL_COMMANDS - Extra NSIS commands that will
          be added to the uninstall Section, before your install tree is
          removed from the target system.

       

          CPACK_NSIS_COMPRESSOR - The arguments that will be passed to the
          NSIS SetCompressor command.

       

          CPACK_NSIS_ENABLE_UNINSTALL_BEFORE_INSTALL - Ask about uninstalling
          previous versions first.
          If this is set to "ON", then an installer will look for previous
          installed versions and if one is found, ask the user whether to
          uninstall it before proceeding with the install.

       

          CPACK_NSIS_MODIFY_PATH - Modify PATH toggle.
          If this is set to "ON", then an extra page
          will appear in the installer that will allow the user to choose
          whether the program directory should be added to the system PATH
          variable.

       

          CPACK_NSIS_DISPLAY_NAME - The display name string that appears in
          the Windows Add/Remove Program control panel

       

          CPACK_NSIS_PACKAGE_NAME - The title displayed at the top of the
          installer.

       

          CPACK_NSIS_INSTALLED_ICON_NAME - A path to the executable that
          contains the installer icon.

       

          CPACK_NSIS_HELP_LINK - URL to a web site providing assistance in
          installing your application.

       

          CPACK_NSIS_URL_INFO_ABOUT - URL to a web site providing more
          information about your application.

       

          CPACK_NSIS_CONTACT - Contact information for questions and comments
          about the installation process.

       

          CPACK_NSIS_CREATE_ICONS_EXTRA - Additional NSIS commands for
          creating start menu shortcuts.

       

          CPACK_NSIS_DELETE_ICONS_EXTRA -Additional NSIS commands to
          uninstall start menu shortcuts.

       

          CPACK_NSIS_EXECUTABLES_DIRECTORY - Creating NSIS start menu links
          assumes that they are in 'bin' unless this variable is set.
          For example, you would set this to 'exec' if your executables are
          in an exec directory.

       

          CPACK_NSIS_MUI_FINISHPAGE_RUN - Specify an executable to add an option
          to run on the finish page of the NSIS installer.
          CPACK_NSIS_MENU_LINKS - Specify links in [application] menu.
          This should contain a list of pair "link" "link name". The link
          may be an URL or a path relative to installation prefix.
          Like:
            set(CPACK_NSIS_MENU_LINKS
                "doc/cmake-@CMake_VERSION_MAJOR@.@CMake_VERSION_MINOR@/cmake.html" "CMake Help"
                "http://www.cmake.org" "CMake Web Site")


  CPackPackageMaker
       PackageMaker CPack generator (Mac OS X).

       The following variable is specific to installers built on Mac OS X
       using PackageMaker:

         CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the
         resulting PackageMaker archive should be compatible with. Different
         versions of Mac OS X support different
         features. For example, CPack can only build component-based
         installers for Mac OS X 10.4 or newer, and can only build
         installers that download component son-the-fly for Mac OS X 10.5
         or newer. If left blank, this value will be set to the minimum
         version of Mac OS X that supports the requested features. Set this
         variable to some value (e.g., 10.4) only if you want to guarantee
         that your installer will work on that version of Mac OS X, and
         don't mind missing extra features available in the installer
         shipping with later versions of Mac OS X.


  CPackRPM
       The builtin (binary) CPack RPM generator (Unix only)

       CPackRPM may be used to create RPM package using CPack.  CPackRPM is a
       CPack generator thus it uses the CPACK_XXX variables used by CPack :
       http://www.cmake.org/Wiki/CMake:CPackConfiguration

       However CPackRPM has specific features which are controlled by the
       specifics CPACK_RPM_XXX variables.  CPackRPM is a component aware
       generator so when CPACK_RPM_COMPONENT_INSTALL is ON some more
       CPACK_RPM_<ComponentName>_XXXX variables may be used in order to have
       component specific values.  Note however that <componentName> refers
       to the **grouping name**.  This may be either a component name or a
       component GROUP name.  Usually those vars correspond to RPM spec file
       entities, one may find information about spec files here
       http://www.rpm.org/wiki/Docs.  You'll find a detailed usage of
       CPackRPM on the wiki:

         http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#RPM_.28Unix_Only.29

       However as a handy reminder here comes the list of specific variables:

         CPACK_RPM_PACKAGE_SUMMARY - The RPM package summary.
            Mandatory : YES
            Default   : CPACK_PACKAGE_DESCRIPTION_SUMMARY
         CPACK_RPM_PACKAGE_NAME - The RPM package name.
            Mandatory : YES
            Default   : CPACK_PACKAGE_NAME
         CPACK_RPM_PACKAGE_VERSION - The RPM package version.
            Mandatory : YES
            Default   : CPACK_PACKAGE_VERSION
         CPACK_RPM_PACKAGE_ARCHITECTURE - The RPM package architecture.
            Mandatory : NO
            Default   : -
            This may be set to "noarch" if you
            know you are building a noarch package.
         CPACK_RPM_PACKAGE_RELEASE - The RPM package release.
            Mandatory : YES
            Default   : 1
            This is the numbering of the RPM package
            itself, i.e. the version of the packaging and not the version of the
            content (see CPACK_RPM_PACKAGE_VERSION). One may change the default
            value if the previous packaging was buggy and/or you want to put here
            a fancy Linux distro specific numbering.
         CPACK_RPM_PACKAGE_LICENSE - The RPM package license policy.
            Mandatory : YES
            Default   : "unknown"
         CPACK_RPM_PACKAGE_GROUP - The RPM package group.
            Mandatory : YES
            Default   : "unknown"
         CPACK_RPM_PACKAGE_VENDOR - The RPM package vendor.
            Mandatory : YES
            Default   : CPACK_PACKAGE_VENDOR if set or "unknown"
         CPACK_RPM_PACKAGE_URL - The projects URL.
            Mandatory : NO
            Default   : -
         CPACK_RPM_PACKAGE_DESCRIPTION - RPM package description.
            Mandatory : YES
            Default   : CPACK_PACKAGE_DESCRIPTION_FILE if set or "no package description available"
         CPACK_RPM_COMPRESSION_TYPE - RPM compression type.
            Mandatory : NO
            Default   : -
            May be used to override RPM compression type to be used
            to build the RPM. For example some Linux distribution now default
            to lzma or xz compression whereas older cannot use such RPM.
            Using this one can enforce compression type to be used.
            Possible value are: lzma, xz, bzip2 and gzip.
         CPACK_RPM_PACKAGE_REQUIRES - RPM spec requires field.
            Mandatory : NO
            Default   : -
            May be used to set RPM dependencies (requires).
            Note that you must enclose the complete requires string between quotes,
            for example:
            set(CPACK_RPM_PACKAGE_REQUIRES "python >= 2.5.0, cmake >= 2.8")
            The required package list of an RPM file could be printed with
            rpm -qp --requires file.rpm
         CPACK_RPM_PACKAGE_SUGGESTS - RPM spec suggest field.
            Mandatory : NO
            Default   : -
            May be used to set weak RPM dependencies (suggests).
            Note that you must enclose the complete requires string between quotes.
         CPACK_RPM_PACKAGE_PROVIDES - RPM spec provides field.
            Mandatory : NO
            Default   : -
            May be used to set RPM dependencies (provides).
            The provided package list of an RPM file could be printed with
            rpm -qp --provides file.rpm
         CPACK_RPM_PACKAGE_OBSOLETES - RPM spec obsoletes field.
            Mandatory : NO
            Default   : -
            May be used to set RPM packages that are obsoleted by this one.
         CPACK_RPM_PACKAGE_RELOCATABLE - build a relocatable RPM.
            Mandatory : NO
            Default   : CPACK_PACKAGE_RELOCATABLE
            If this variable is set to TRUE or ON CPackRPM will try
            to build a relocatable RPM package. A relocatable RPM may
            be installed using rpm --prefix or --relocate in order to
            install it at an alternate place see rpm(8).
            Note that currently this may fail if CPACK_SET_DESTDIR is set to ON.
            If CPACK_SET_DESTDIR is set then you will get a warning message
            but if there is file installed with absolute path you'll get
            unexpected behavior.
         CPACK_RPM_SPEC_INSTALL_POST - [deprecated].
            Mandatory : NO
            Default   : -
            This way of specifying post-install script is deprecated use
            CPACK_RPM_POST_INSTALL_SCRIPT_FILE
            May be used to set an RPM post-install command inside the spec file.
            For example setting it to "/bin/true" may be used to prevent
            rpmbuild to strip binaries.
         CPACK_RPM_SPEC_MORE_DEFINE - RPM extended spec definitions lines.
            Mandatory : NO
            Default   : -
            May be used to add any %define lines to the generated spec file.
         CPACK_RPM_PACKAGE_DEBUG - Toggle CPackRPM debug output.
            Mandatory : NO
            Default   : -
            May be set when invoking cpack in order to trace debug information
            during CPack RPM run. For example you may launch CPack like this
            cpack -D CPACK_RPM_PACKAGE_DEBUG=1 -G RPM
         CPACK_RPM_USER_BINARY_SPECFILE - A user provided spec file.
            Mandatory : NO
            Default   : -
            May be set by the user in order to specify a USER binary spec file
            to be used by CPackRPM instead of generating the file.
            The specified file will be processed by configure_file( @ONLY).
            One can provide a component specific file by setting
            CPACK_RPM_<componentName>_USER_BINARY_SPECFILE.
         CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE - Spec file template.
            Mandatory : NO
            Default   : -
            If set CPack will generate a template for USER specified binary
            spec file and stop with an error. For example launch CPack like this
            cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM
            The user may then use this file in order to hand-craft is own
            binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE.
         CPACK_RPM_PRE_INSTALL_SCRIPT_FILE
         CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE
            Mandatory : NO
            Default   : -
            May be used to embed a pre (un)installation script in the spec file.
            The refered script file(s) will be read and directly
            put after the %pre or %preun section
            If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
            each component can be overridden with
            CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE and
            CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE
            One may verify which scriptlet has been included with
             rpm -qp --scripts  package.rpm
         CPACK_RPM_POST_INSTALL_SCRIPT_FILE
         CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE
            Mandatory : NO
            Default   : -
            May be used to embed a post (un)installation script in the spec file.
            The refered script file(s) will be read and directly
            put after the %post or %postun section
            If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for
            each component can be overridden with
            CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE and
            CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE
            One may verify which scriptlet has been included with
             rpm -qp --scripts  package.rpm
         CPACK_RPM_USER_FILELIST
         CPACK_RPM_<COMPONENT>_USER_FILELIST
            Mandatory : NO
            Default   : -
            May be used to explicitly specify %(<directive>) file line
            in the spec file. Like %config(noreplace) or any other directive
            that be found in the %files section. Since CPackRPM is generating
            the list of files (and directories) the user specified files of
            the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the generated list.
         CPACK_RPM_CHANGELOG_FILE - RPM changelog file.
            Mandatory : NO
            Default   : -
            May be used to embed a changelog in the spec file.
            The refered file will be read and directly put after the %changelog
            section.
         CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST - list of path to be excluded.
            Mandatory : NO
            Default   : /etc /etc/init.d /usr /usr/share /usr/share/doc /usr/bin /usr/lib /usr/lib64 /usr/include
            May be used to exclude path (directories or files) from the auto-generated
            list of paths discovered by CPack RPM. The defaut value contains a reasonable
            set of values if the variable is not defined by the user. If the variable
            is defined by the user then CPackRPM will NOT any of the default path.
            If you want to add some path to the default list then you can use
            CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION variable.
         CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION - additional list of path to be excluded.
            Mandatory : NO
            Default   : -
            May be used to add more exclude path (directories or files) from the initial
            default list of excluded paths. See CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST.


  CPackWIX
       CPack WiX generator specific options

       

       The following variables are specific to the installers built on
       Windows using WiX.

         CPACK_WIX_UPGRADE_GUID - Upgrade GUID (Product/@UpgradeCode)

       

       Will be automatically generated unless explicitly provided.

       It should be explicitly set to a constant generated gloabally unique
       identifier (GUID) to allow your installers to replace existing
       installations that use the same GUID.

       You may for example explicitly set this variable in your
       CMakeLists.txt to the value that has been generated per default.  You
       should not use GUIDs that you did not generate yourself or which may
       belong to other projects.

       A GUID shall have the following fixed length syntax:
       XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

         (each X represents an uppercase hexadecimal digit)
         CPACK_WIX_PRODUCT_GUID - Product GUID (Product/@Id)

       

       Will be automatically generated unless explicitly provided.

       If explicitly provided this will set the Product Id of your installer.

       The installer will abort if it detects a pre-existing installation
       that uses the same GUID.

       The GUID shall use the syntax described for CPACK_WIX_UPGRADE_GUID.

         CPACK_WIX_LICENSE_RTF - RTF License File

       

       If CPACK_RESOURCE_FILE_LICENSE has an .rtf extension it is used as-is.

       If CPACK_RESOURCE_FILE_LICENSE has an .txt extension it is implicitly
       converted to RTF by the WiX Generator.

       With CPACK_WIX_LICENSE_RTF you can override the license file used by
       the WiX Generator in case CPACK_RESOURCE_FILE_LICENSE is in an
       unsupported format or the .txt -> .rtf conversion does not work as
       expected.

       

       CPACK_WIX_PRODUCT_ICON - The Icon shown next to the program name in
       Add/Remove programs.

       If set, this icon is used in place of the default icon.

       

       CPACK_WIX_UI_BANNER - The bitmap will appear at the top of all
       installer pages other than the welcome and completion dialogs.

       If set, this image will replace the default banner image.

       This image must be 493 by 58 pixels.

       

       CPACK_WIX_UI_DIALOG - Background bitmap used on the welcome and
       completion dialogs.

       If this variable is set, the installer will replace the default dialog
       image.

       This image must be 493 by 312 pixels.

       

       CPACK_WIX_PROGRAM_MENU_FOLDER - Start menu folder name for launcher.

       If this variable is not set, it will be initialized with
       CPACK_PACKAGE_NAME

       CPACK_WIX_CULTURES - Language(s) of the installer

       Languages are compiled into the WixUI extension library.  To use them,
       simply provide the name of the culture.  If you specify more than one
       culture identifier in a comma or semicolon delimited list, the first
       one that is found will be used.  You can find a list of supported
       languages at:
       http://wix.sourceforge.net/manual-wix3/WixUI_localization.htm

       CPACK_WIX_TEMPLATE - Template file for WiX generation

       If this variable is set, the specified template will be used to
       generate the WiX wxs file.  This should be used if further
       customization of the output is required.

       If this variable is not set, the default MSI template included with
       CMake will be used.


  CTest
       Configure a project for testing with CTest/CDash

       Include this module in the top CMakeLists.txt file of a project to
       enable testing with CTest and dashboard submissions to CDash:

          project(MyProject)
          ...
          include(CTest)

       The module automatically creates a BUILD_TESTING option that selects
       whether to enable testing support (ON by default).  After including
       the module, use code like

          if(BUILD_TESTING)
            # ... CMake code to create tests ...
          endif()

       to creating tests when testing is enabled.

       To enable submissions to a CDash server, create a CTestConfig.cmake
       file at the top of the project with content such as

          set(CTEST_PROJECT_NAME "MyProject")
          set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC")
          set(CTEST_DROP_METHOD "http")
          set(CTEST_DROP_SITE "my.cdash.org")
          set(CTEST_DROP_LOCATION "/submit.php?project=MyProject")
          set(CTEST_DROP_SITE_CDASH TRUE)

       (the CDash server can provide the file to a project administrator who
       configures 'MyProject').  Settings in the config file are shared by
       both this CTest module and the CTest command-line tool's dashboard
       script mode (ctest -S).

       While building a project for submission to CDash, CTest scans the
       build output for errors and warnings and reports them with surrounding
       context from the build log.  This generic approach works for all build
       tools, but does not give details about the command invocation that
       produced a given problem.  One may get more detailed reports by adding

          set(CTEST_USE_LAUNCHERS 1)

       to the CTestConfig.cmake file.  When this option is enabled, the CTest
       module tells CMake's Makefile generators to invoke every command in
       the generated build system through a CTest launcher program.
       (Currently the CTEST_USE_LAUNCHERS option is ignored on non-Makefile
       generators.) During a manual build each launcher transparently runs
       the command it wraps.  During a CTest-driven build for submission to
       CDash each launcher reports detailed information when its command
       fails or warns.  (Setting CTEST_USE_LAUNCHERS in CTestConfig.cmake is
       convenient, but also adds the launcher overhead even for manual
       builds.  One may instead set it in a CTest dashboard script and add it
       to the CMake cache for the build tree.)

  CTestScriptMode
        

       This file is read by ctest in script mode (-S)

  CTestUseLaunchers
       Set the RULE_LAUNCH_* global properties when CTEST_USE_LAUNCHERS is
       on.

       CTestUseLaunchers is automatically included when you include(CTest).
       However, it is split out into its own module file so projects can use
       the CTEST_USE_LAUNCHERS functionality independently.

       To use launchers, set CTEST_USE_LAUNCHERS to ON in a ctest -S
       dashboard script, and then also set it in the cache of the configured
       project.  Both cmake and ctest need to know the value of it for the
       launchers to work properly.  CMake needs to know in order to generate
       proper build rules, and ctest, in order to produce the proper error
       and warning analysis.

       For convenience, you may set the ENV variable
       CTEST_USE_LAUNCHERS_DEFAULT in your ctest -S script, too.  Then, as
       long as your CMakeLists uses include(CTest) or
       include(CTestUseLaunchers), it will use the value of the ENV variable
       to initialize a CTEST_USE_LAUNCHERS cache variable.  This cache
       variable initialization only occurs if CTEST_USE_LAUNCHERS is not
       already defined.

  CheckCCompilerFlag
       Check whether the C compiler supports a given flag.

       CHECK_C_COMPILER_FLAG(<flag> <var>)

         <flag> - the compiler flag
         <var>  - variable to store the result

       This internally calls the check_c_source_compiles macro and sets
       CMAKE_REQUIRED_DEFINITIONS to <flag>.  See help for
       CheckCSourceCompiles for a listing of variables that can otherwise
       modify the build.  The result only tells that the compiler does not
       give an error message when it encounters the flag.  If the flag has
       any effect or even a specific one is beyond the scope of this module.

  CheckCSourceCompiles
       Check if given C source compiles and links into an executable

       CHECK_C_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>])

         <code>       - source code to try to compile, must define 'main'
         <var>        - variable to store whether the source code compiled
         <fail-regex> - fail if test output matches this regex

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckCSourceRuns
       Check if the given C source code compiles and runs.

       CHECK_C_SOURCE_RUNS(<code> <var>)

         <code>   - source code to try to compile
         <var>    - variable to store the result
                    (1 for success, empty for failure)

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckCXXCompilerFlag
       Check whether the CXX compiler supports a given flag.

       CHECK_CXX_COMPILER_FLAG(<flag> <var>)

         <flag> - the compiler flag
         <var>  - variable to store the result

       This internally calls the check_cxx_source_compiles macro and sets
       CMAKE_REQUIRED_DEFINITIONS to <flag>.  See help for
       CheckCXXSourceCompiles for a listing of variables that can otherwise
       modify the build.  The result only tells that the compiler does not
       give an error message when it encounters the flag.  If the flag has
       any effect or even a specific one is beyond the scope of this module.

  CheckCXXSourceCompiles
       Check if given C++ source compiles and links into an executable

       CHECK_CXX_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>])

         <code>       - source code to try to compile, must define 'main'
         <var>        - variable to store whether the source code compiled
         <fail-regex> - fail if test output matches this regex

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckCXXSourceRuns
       Check if the given C++ source code compiles and runs.

       CHECK_CXX_SOURCE_RUNS(<code> <var>)

         <code>   - source code to try to compile
         <var>    - variable to store the result
                    (1 for success, empty for failure)

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags

         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckCXXSymbolExists
       Check if a symbol exists as a function, variable, or macro in C++

       CHECK_CXX_SYMBOL_EXISTS(<symbol> <files> <variable>)

       Check that the <symbol> is available after including given header
       <files> and store the result in a <variable>.  Specify the list of
       files in one argument as a semicolon-separated list.
       CHECK_CXX_SYMBOL_EXISTS() can be used to check in C++ files, as
       opposed to CHECK_SYMBOL_EXISTS(), which works only for C.

       If the header files define the symbol as a macro it is considered
       available and assumed to work.  If the header files declare the symbol
       as a function or variable then the symbol must also be available for
       linking.  If the symbol is a type or enum value it will not be
       recognized (consider using CheckTypeSize or CheckCSourceCompiles).

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags

         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckFunctionExists
       Check if a C function can be linked

       CHECK_FUNCTION_EXISTS(<function> <variable>)

       Check that the <function> is provided by libraries on the system and
       store the result in a <variable>.  This does not verify that any
       system header file declares the function, only that it can be found at
       link time (consider using CheckSymbolExists).

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckIncludeFile
       macro which checks the include file exists.

       CHECK_INCLUDE_FILE(INCLUDE VARIABLE)

         INCLUDE  - name of include file
         VARIABLE - variable to return result

       

       an optional third argument is the CFlags to add to the compile line or
       you can use CMAKE_REQUIRED_FLAGS

         CMAKE_REQUIRED_INCLUDES = list of include directories

       


  CheckIncludeFileCXX
       Check if the include file exists.

         CHECK_INCLUDE_FILE_CXX(INCLUDE VARIABLE)

       

         INCLUDE  - name of include file
         VARIABLE - variable to return result

       

       An optional third argument is the CFlags to add to the compile line or
       you can use CMAKE_REQUIRED_FLAGS.

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags

       CHECK_INCLUDE_FILES(INCLUDE VARIABLE)

         INCLUDE  - list of files to include
         VARIABLE - variable to return result

       

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories


  CheckLanguage
       Check if a language can be enabled

       Usage:

         check_language(<lang>)

       where <lang> is a language that may be passed to enable_language()
       such as "Fortran".  If CMAKE_<lang>_COMPILER is already defined the
       check does nothing.  Otherwise it tries enabling the language in a
       test project.  The result is cached in CMAKE_<lang>_COMPILER as the
       compiler that was found, or NOTFOUND if the language cannot be
       enabled.

       Example:

         check_language(Fortran)
         if(CMAKE_Fortran_COMPILER)
           enable_language(Fortran)
         else()
           message(STATUS "No Fortran support")
         endif()


  CheckLibraryExists
       Check if the function exists.

       CHECK_LIBRARY_EXISTS (LIBRARY FUNCTION LOCATION VARIABLE)

         LIBRARY  - the name of the library you are looking for
         FUNCTION - the name of the function
         LOCATION - location where the library should be found
         VARIABLE - variable to store the result

       

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckPrototypeDefinition
       Check if the protoype we expect is correct.

       check_prototype_definition(FUNCTION PROTOTYPE RETURN HEADER VARIABLE)

         FUNCTION - The name of the function (used to check if prototype exists)
         PROTOTYPE- The prototype to check.
         RETURN - The return value of the function.
         HEADER - The header files required.
         VARIABLE - The variable to store the result.

       Example:

         check_prototype_definition(getpwent_r
          "struct passwd *getpwent_r(struct passwd *src, char *buf, int buflen)"
          "NULL"
          "unistd.h;pwd.h"
          SOLARIS_GETPWENT_R)

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories

  CheckStructHasMember
       Check if the given struct or class has the specified member variable

       CHECK_STRUCT_HAS_MEMBER (STRUCT MEMBER HEADER VARIABLE)

         STRUCT - the name of the struct or class you are interested in
         MEMBER - the member which existence you want to check
         HEADER - the header(s) where the prototype should be declared
         VARIABLE - variable to store the result

       

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories

       

       Example: CHECK_STRUCT_HAS_MEMBER("struct timeval" tv_sec sys/select.h
       HAVE_TIMEVAL_TV_SEC)

  CheckSymbolExists
       Check if a symbol exists as a function, variable, or macro

       CHECK_SYMBOL_EXISTS(<symbol> <files> <variable>)

       Check that the <symbol> is available after including given header
       <files> and store the result in a <variable>.  Specify the list of
       files in one argument as a semicolon-separated list.

       If the header files define the symbol as a macro it is considered
       available and assumed to work.  If the header files declare the symbol
       as a function or variable then the symbol must also be available for
       linking.  If the symbol is a type or enum value it will not be
       recognized (consider using CheckTypeSize or CheckCSourceCompiles).  If
       the check needs to be done in C++, consider using
       CHECK_CXX_SYMBOL_EXISTS(), which does the same as
       CHECK_SYMBOL_EXISTS(), but in C++.

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  CheckTypeSize
       Check sizeof a type

         CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY])

       Check if the type exists and determine its size.  On return,
       "HAVE_${VARIABLE}" holds the existence of the type, and "${VARIABLE}"
       holds one of the following:

          <size> = type has non-zero size <size>
          "0"    = type has arch-dependent size (see below)
          ""     = type does not exist

       Furthermore, the variable "${VARIABLE}_CODE" holds C preprocessor code
       to define the macro "${VARIABLE}" to the size of the type, or leave
       the macro undefined if the type does not exist.

       The variable "${VARIABLE}" may be "0" when CMAKE_OSX_ARCHITECTURES has
       multiple architectures for building OS X universal binaries.  This
       indicates that the type size varies across architectures.  In this
       case "${VARIABLE}_CODE" contains C preprocessor tests mapping from
       each architecture macro to the corresponding type size.  The list of
       architecture macros is stored in "${VARIABLE}_KEYS", and the value for
       each key is stored in "${VARIABLE}-${KEY}".

       If the BUILTIN_TYPES_ONLY option is not given, the macro checks for
       headers <sys/types.h>, <stdint.h>, and <stddef.h>, and saves results
       in HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H.  The type size
       check automatically includes the available headers, thus supporting
       checks of types defined in the headers.

       Despite the name of the macro you may use it to check the size of more
       complex expressions, too.  To check e.g.  for the size of a struct
       member you can do something like this:

         check_type_size("((struct something*)0)->member" SIZEOF_MEMBER)

       

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_INCLUDES = list of include directories
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link
         CMAKE_EXTRA_INCLUDE_FILES = list of extra headers to include


  CheckVariableExists
       Check if the variable exists.

         CHECK_VARIABLE_EXISTS(VAR VARIABLE)

       

         VAR      - the name of the variable
         VARIABLE - variable to store the result

       

       This macro is only for C variables.

       The following variables may be set before calling this macro to modify
       the way the check is run:

         CMAKE_REQUIRED_FLAGS = string of compile command line flags
         CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
         CMAKE_REQUIRED_LIBRARIES = list of libraries to link


  Dart
       Configure a project for testing with CTest or old Dart Tcl Client

       This file is the backwards-compatibility version of the CTest module.
       It supports using the old Dart 1 Tcl client for driving dashboard
       submissions as well as testing with CTest.  This module should be
       included in the CMakeLists.txt file at the top of a project.  Typical
       usage:

         include(Dart)
         if(BUILD_TESTING)
           # ... testing related CMake code ...
         endif()

       The BUILD_TESTING option is created by the Dart module to determine
       whether testing support should be enabled.  The default is ON.

  DeployQt4
       Functions to help assemble a standalone Qt4 executable.

       A collection of CMake utility functions useful for deploying Qt4
       executables.

       The following functions are provided by this module:

          write_qt4_conf
          resolve_qt4_paths
          fixup_qt4_executable
          install_qt4_plugin_path
          install_qt4_plugin
          install_qt4_executable

       Requires CMake 2.6 or greater because it uses function and
       PARENT_SCOPE.  Also depends on BundleUtilities.cmake.

         WRITE_QT4_CONF(<qt_conf_dir> <qt_conf_contents>)

       Writes a qt.conf file with the <qt_conf_contents> into <qt_conf_dir>.

         RESOLVE_QT4_PATHS(<paths_var> [<executable_path>])

       Loop through <paths_var> list and if any don't exist resolve them
       relative to the <executable_path> (if supplied) or the
       CMAKE_INSTALL_PREFIX.

         FIXUP_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf>])

       Copies Qt plugins, writes a Qt configuration file (if needed) and
       fixes up a Qt4 executable using BundleUtilities so it is standalone
       and can be drag-and-drop copied to another machine as long as all of
       the system libraries are compatible.

       <executable> should point to the executable to be fixed-up.

       <qtplugins> should contain a list of the names or paths of any Qt
       plugins to be installed.

       <libs> will be passed to BundleUtilities and should be a list of any
       already installed plugins, libraries or executables to also be
       fixed-up.

       <dirs> will be passed to BundleUtilities and should contain and
       directories to be searched to find library dependencies.

       <plugins_dir> allows an custom plugins directory to be used.

       <request_qt_conf> will force a qt.conf file to be written even if not
       needed.

         INSTALL_QT4_PLUGIN_PATH(plugin executable copy installed_plugin_path_var <plugins_dir> <component> <configurations>)

       Install (or copy) a resolved <plugin> to the default plugins directory
       (or <plugins_dir>) relative to <executable> and store the result in
       <installed_plugin_path_var>.

       If <copy> is set to TRUE then the plugins will be copied rather than
       installed.  This is to allow this module to be used at CMake time
       rather than install time.

       If <component> is set then anything installed will use this COMPONENT.

         INSTALL_QT4_PLUGIN(plugin executable copy installed_plugin_path_var <plugins_dir> <component>)

       Install (or copy) an unresolved <plugin> to the default plugins
       directory (or <plugins_dir>) relative to <executable> and store the
       result in <installed_plugin_path_var>.  See documentation of
       INSTALL_QT4_PLUGIN_PATH.

         INSTALL_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf> <component>])

       Installs Qt plugins, writes a Qt configuration file (if needed) and
       fixes up a Qt4 executable using BundleUtilities so it is standalone
       and can be drag-and-drop copied to another machine as long as all of
       the system libraries are compatible.  The executable will be fixed-up
       at install time.  <component> is the COMPONENT used for bundle fixup
       and plugin installation.  See documentation of FIXUP_QT4_BUNDLE.

  Documentation
       DocumentationVTK.cmake

       This file provides support for the VTK documentation framework.  It
       relies on several tools (Doxygen, Perl, etc).

  ExternalData
       Manage data files stored outside source tree

       Use this module to unambiguously reference data files stored outside
       the source tree and fetch them at build time from arbitrary local and
       remote content-addressed locations.  Functions provided by this module
       recognize arguments with the syntax "DATA{<name>}" as references to
       external data, replace them with full paths to local copies of those
       data, and create build rules to fetch and update the local copies.

       The DATA{} syntax is literal and the <name> is a full or relative path
       within the source tree.  The source tree must contain either a real
       data file at <name> or a "content link" at <name><ext> containing a
       hash of the real file using a hash algorithm corresponding to <ext>.
       For example, the argument "DATA{img.png}" may be satisfied by either a
       real "img.png" file in the current source directory or a "img.png.md5"
       file containing its MD5 sum.

       The 'ExternalData_Expand_Arguments' function evaluates DATA{}
       references in its arguments and constructs a new list of arguments:

         ExternalData_Expand_Arguments(
           <target>   # Name of data management target
           <outVar>   # Output variable
           [args...]  # Input arguments, DATA{} allowed
           )

       It replaces each DATA{} reference in an argument with the full path of
       a real data file on disk that will exist after the <target> builds.

       The 'ExternalData_Add_Test' function wraps around the CMake add_test()
       command but supports DATA{} references in its arguments:

         ExternalData_Add_Test(
           <target>   # Name of data management target
           ...        # Arguments of add_test(), DATA{} allowed
           )

       It passes its arguments through ExternalData_Expand_Arguments and then
       invokes add_test() using the results.

       The 'ExternalData_Add_Target' function creates a custom target to
       manage local instances of data files stored externally:

         ExternalData_Add_Target(
           <target>   # Name of data management target
           )

       It creates custom commands in the target as necessary to make data
       files available for each DATA{} reference previously evaluated by
       other functions provided by this module.  A list of URL templates must
       be provided in the variable ExternalData_URL_TEMPLATES using the
       placeholders "%(algo)" and "%(hash)" in each template.  Data fetch
       rules try each URL template in order by substituting the hash
       algorithm name for "%(algo)" and the hash value for "%(hash)".

       The following hash algorithms are supported:

           %(algo)     <ext>     Description

       Note that the hashes are used only for unique data identification and
       download verification.  This is not security software.

       Example usage:

          include(ExternalData)
          set(ExternalData_URL_TEMPLATES "file:///local/%(algo)/%(hash)"
                                         "http://data.org/%(algo)/%(hash)")
          ExternalData_Add_Test(MyData
            NAME MyTest
            COMMAND MyExe DATA{MyInput.png}
            )
          ExternalData_Add_Target(MyData)

       When test "MyTest" runs the "DATA{MyInput.png}" argument will be
       replaced by the full path to a real instance of the data file
       "MyInput.png" on disk.  If the source tree contains a content link
       such as "MyInput.png.md5" then the "MyData" target creates a real
       "MyInput.png" in the build tree.

       The DATA{} syntax can be told to fetch a file series using the form
       "DATA{<name>,:}", where the ":" is literal.  If the source tree
       contains a group of files or content links named like a series then a
       reference to one member adds rules to fetch all of them.  Although all
       members of a series are fetched, only the file originally named by the
       DATA{} argument is substituted for it.  The default configuration
       recognizes file series names ending with "#.ext", "_#.ext", ".#.ext",
       or "-#.ext" where "#" is a sequence of decimal digits and ".ext" is
       any single extension.  Configure it with a regex that parses <number>
       and <suffix> parts from the end of <name>:

         ExternalData_SERIES_PARSE = regex of the form (<number>)(<suffix>)$

       For more complicated cases set:

         ExternalData_SERIES_PARSE = regex with at least two () groups
         ExternalData_SERIES_PARSE_PREFIX = <prefix> regex group number, if any
         ExternalData_SERIES_PARSE_NUMBER = <number> regex group number
         ExternalData_SERIES_PARSE_SUFFIX = <suffix> regex group number

       Configure series number matching with a regex that matches the
       <number> part of series members named <prefix><number><suffix>:

         ExternalData_SERIES_MATCH = regex matching <number> in all series members

       Note that the <suffix> of a series does not include a hash-algorithm
       extension.

       The DATA{} syntax can alternatively match files associated with the
       named file and contained in the same directory.  Associated files may
       be specified by options using the syntax
       DATA{<name>,<opt1>,<opt2>,...}.  Each option may specify one file by
       name or specify a regular expression to match file names using the
       syntax REGEX:<regex>.  For example, the arguments

          DATA{MyData/MyInput.mhd,MyInput.img}                   # File pair
          DATA{MyData/MyFrames00.png,REGEX:MyFrames[0-9]+\\.png} # Series

       will pass MyInput.mha and MyFrames00.png on the command line but
       ensure that the associated files are present next to them.

       The DATA{} syntax may reference a directory using a trailing slash and
       a list of associated files.  The form DATA{<name>/,<opt1>,<opt2>,...}
       adds rules to fetch any files in the directory that match one of the
       associated file options.  For example, the argument
       DATA{MyDataDir/,REGEX:.*} will pass the full path to a MyDataDir
       directory on the command line and ensure that the directory contains
       files corresponding to every file or content link in the MyDataDir
       source directory.

       The variable ExternalData_LINK_CONTENT may be set to the name of a
       supported hash algorithm to enable automatic conversion of real data
       files referenced by the DATA{} syntax into content links.  For each
       such <file> a content link named "<file><ext>" is created.  The
       original file is renamed to the form ".ExternalData_<algo>_<hash>" to
       stage it for future transmission to one of the locations in the list
       of URL templates (by means outside the scope of this module).  The
       data fetch rule created for the content link will use the staged
       object if it cannot be found using any URL template.

       The variable ExternalData_OBJECT_STORES may be set to a list of local
       directories that store objects using the layout <dir>/%(algo)/%(hash).
       These directories will be searched first for a needed object.  If the
       object is not available in any store then it will be fetched remotely
       using the URL templates and added to the first local store listed.  If
       no stores are specified the default is a location inside the build
       tree.

       The variable ExternalData_SOURCE_ROOT may be set to the highest source
       directory containing any path named by a DATA{} reference.  The
       default is CMAKE_SOURCE_DIR.  ExternalData_SOURCE_ROOT and
       CMAKE_SOURCE_DIR must refer to directories within a single source
       distribution (e.g.  they come together in one tarball).

       The variable ExternalData_BINARY_ROOT may be set to the directory to
       hold the real data files named by expanded DATA{} references.  The
       default is CMAKE_BINARY_DIR.  The directory layout will mirror that of
       content links under ExternalData_SOURCE_ROOT.

       Variables ExternalData_TIMEOUT_INACTIVITY and
       ExternalData_TIMEOUT_ABSOLUTE set the download inactivity and absolute
       timeouts, in seconds.  The defaults are 60 seconds and 300 seconds,
       respectively.  Set either timeout to 0 seconds to disable enforcement.

  ExternalProject
       Create custom targets to build projects in external trees

       The 'ExternalProject_Add' function creates a custom target to drive
       download, update/patch, configure, build, install and test steps of an
       external project:

         ExternalProject_Add(<name>    # Name for custom target
           [DEPENDS projects...]       # Targets on which the project depends
           [PREFIX dir]                # Root dir for entire project

           [TLS_VERIFY bool]           # Should certificate for https be checked
           [TLS_CAINFO file]           # Path to a certificate authority file
           [TIMEOUT seconds]           # Time allowed for file download operations
          #--Update/Patch step----------
           [UPDATE_COMMAND cmd...]     # Source work-tree update command
           [PATCH_COMMAND cmd...]      # Command to patch downloaded source
          #--Configure step-------------
           [SOURCE_DIR dir]            # Source dir to be used for build

           [CMAKE_COMMAND /.../cmake]  # Specify alternative cmake executable
           [CMAKE_GENERATOR gen]       # Specify generator for native build
           [CMAKE_GENERATOR_TOOLSET t] # Generator-specific toolset name
           [CMAKE_ARGS args...]        # Arguments to CMake command line
           [CMAKE_CACHE_ARGS args...]  # Initial cache arguments, of the form -Dvar:string=on

           [BINARY_DIR dir]            # Specify build dir location
           [BUILD_COMMAND cmd...]      # Command to drive the native build
           [BUILD_IN_SOURCE 1]         # Use source dir for build dir
          #--Install step---------------
           [INSTALL_DIR dir]           # Installation prefix
           [INSTALL_COMMAND cmd...]    # Command to drive install after build
          #--Test step------------------
           [TEST_BEFORE_INSTALL 1]     # Add test step executed before install step
           [TEST_AFTER_INSTALL 1]      # Add test step executed after install step
           [TEST_COMMAND cmd...]       # Command to drive test
          #--Output logging-------------
           [LOG_DOWNLOAD 1]            # Wrap download in script to log output
           [LOG_UPDATE 1]              # Wrap update in script to log output
           [LOG_CONFIGURE 1]           # Wrap configure in script to log output
           [LOG_BUILD 1]               # Wrap build in script to log output
           [LOG_TEST 1]                # Wrap test in script to log output
           [LOG_INSTALL 1]             # Wrap install in script to log output
          #--Custom targets-------------
           [STEP_TARGETS st1 st2 ...]  # Generate custom targets for these steps
           )

       The *_DIR options specify directories for the project, with default
       directories computed as follows.  If the PREFIX option is given to
       ExternalProject_Add() or the EP_PREFIX directory property is set, then
       an external project is built and installed under the specified prefix:

          TMP_DIR      = <prefix>/tmp
          STAMP_DIR    = <prefix>/src/<name>-stamp
          DOWNLOAD_DIR = <prefix>/src
          SOURCE_DIR   = <prefix>/src/<name>
          BINARY_DIR   = <prefix>/src/<name>-build
          INSTALL_DIR  = <prefix>

       Otherwise, if the EP_BASE directory property is set then components of
       an external project are stored under the specified base:

          TMP_DIR      = <base>/tmp/<name>
          STAMP_DIR    = <base>/Stamp/<name>
          DOWNLOAD_DIR = <base>/Download/<name>
          SOURCE_DIR   = <base>/Source/<name>
          BINARY_DIR   = <base>/Build/<name>
          INSTALL_DIR  = <base>/Install/<name>

       If no PREFIX, EP_PREFIX, or EP_BASE is specified then the default is
       to set PREFIX to "<name>-prefix".  Relative paths are interpreted with
       respect to the build directory corresponding to the source directory
       in which ExternalProject_Add is invoked.

       If SOURCE_DIR is explicitly set to an existing directory the project
       will be built from it.  Otherwise a download step must be specified
       using one of the DOWNLOAD_COMMAND, CVS_*, SVN_*, or URL options.  The
       URL option may refer locally to a directory or source tarball, or
       refer to a remote tarball (e.g.  http://.../src.tgz).

       The 'ExternalProject_Add_Step' function adds a custom step to an
       external project:

         ExternalProject_Add_Step(<name> <step> # Names of project and custom step
           [COMMAND cmd...]        # Command line invoked by this step
           [COMMENT "text..."]     # Text printed when step executes
           [DEPENDEES steps...]    # Steps on which this step depends
           [DEPENDERS steps...]    # Steps that depend on this step
           [DEPENDS files...]      # Files on which this step depends
           [ALWAYS 1]              # No stamp file, step always runs
           [WORKING_DIRECTORY dir] # Working directory for command
           [LOG 1]                 # Wrap step in script to log output
           )

       The command line, comment, and working directory of every standard and
       custom step is processed to replace tokens <SOURCE_DIR>, <BINARY_DIR>,
       <INSTALL_DIR>, and <TMP_DIR> with corresponding property values.

       Any builtin step that specifies a "<step>_COMMAND cmd..." or custom
       step that specifies a "COMMAND cmd..." may specify additional command
       lines using the form "COMMAND cmd...".  At build time the commands
       will be executed in order and aborted if any one fails.  For example:

         ... BUILD_COMMAND make COMMAND echo done ...

       specifies to run "make" and then "echo done" during the build step.
       Whether the current working directory is preserved between commands is
       not defined.  Behavior of shell operators like "&&" is not defined.

       The 'ExternalProject_Get_Property' function retrieves external project
       target properties:

         ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]])

       It stores property values in variables of the same name.  Property
       names correspond to the keyword argument names of
       'ExternalProject_Add'.

       The 'ExternalProject_Add_StepTargets' function generates custom
       targets for the steps listed:

         ExternalProject_Add_StepTargets(<name> [step1 [step2 [...]]])

       

       If STEP_TARGETS is set then ExternalProject_Add_StepTargets is
       automatically called at the end of matching calls to
       ExternalProject_Add_Step.  Pass STEP_TARGETS explicitly to individual
       ExternalProject_Add calls, or implicitly to all ExternalProject_Add
       calls by setting the directory property EP_STEP_TARGETS.

       If STEP_TARGETS is not set, clients may still manually call
       ExternalProject_Add_StepTargets after calling ExternalProject_Add or
       ExternalProject_Add_Step.

       This functionality is provided to make it easy to drive the steps
       independently of each other by specifying targets on build command
       lines.  For example, you may be submitting to a sub-project based
       dashboard, where you want to drive the configure portion of the build,
       then submit to the dashboard, followed by the build portion, followed
       by tests.  If you invoke a custom target that depends on a step
       halfway through the step dependency chain, then all the previous steps
       will also run to ensure everything is up to date.

       For example, to drive configure, build and test steps independently
       for each ExternalProject_Add call in your project, write the following
       line prior to any ExternalProject_Add calls in your CMakeLists file:

          set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test)


  FeatureSummary
       Macros for generating a summary of enabled/disabled features

       

       This module provides the macros feature_summary(),
       set_package_properties() and add_feature_info().  For compatibility it
       also still provides set_package_info(), set_feature_info(),
       print_enabled_features() and print_disabled_features().

       These macros can be used to generate a summary of enabled and disabled
       packages and/or feature for a build tree:

           -- The following OPTIONAL packages have been found:
           LibXml2 (required version >= 2.4) , XML processing library. , <http://xmlsoft.org>
              * Enables HTML-import in MyWordProcessor
              * Enables odt-export in MyWordProcessor
           PNG , A PNG image library. , <http://www.libpng.org/pub/png/>
              * Enables saving screenshots
           -- The following OPTIONAL packages have not been found:
           Lua51 , The Lua scripting language. , <http://www.lua.org>
              * Enables macros in MyWordProcessor
           Foo , Foo provides cool stuff.

       

       

           FEATURE_SUMMARY( [FILENAME <file>]
                            [APPEND]
                            [VAR <variable_name>]
                            [INCLUDE_QUIET_PACKAGES]
                            [FATAL_ON_MISSING_REQUIRED_PACKAGES]
                            [DESCRIPTION "Found packages:"]
                            WHAT (ALL | PACKAGES_FOUND | PACKAGES_NOT_FOUND
                                 | ENABLED_FEATURES | DISABLED_FEATURES]
                          )

       

       The FEATURE_SUMMARY() macro can be used to print information about
       enabled or disabled packages or features of a project.  By default,
       only the names of the features/packages will be printed and their
       required version when one was specified.  Use SET_PACKAGE_PROPERTIES()
       to add more useful information, like e.g.  a download URL for the
       respective package or their purpose in the project.

       The WHAT option is the only mandatory option.  Here you specify what
       information will be printed:

           ALL: print everything
           ENABLED_FEATURES: the list of all features which are enabled
           DISABLED_FEATURES: the list of all features which are disabled
           PACKAGES_FOUND: the list of all packages which have been found
           PACKAGES_NOT_FOUND: the list of all packages which have not been found
           OPTIONAL_PACKAGES_FOUND: only those packages which have been found which have the type OPTIONAL
           OPTIONAL_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type OPTIONAL
           RECOMMENDED_PACKAGES_FOUND: only those packages which have been found which have the type RECOMMENDED
           RECOMMENDED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RECOMMENDED
           REQUIRED_PACKAGES_FOUND: only those packages which have been found which have the type REQUIRED
           REQUIRED_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type REQUIRED
           RUNTIME_PACKAGES_FOUND: only those packages which have been found which have the type RUNTIME
           RUNTIME_PACKAGES_NOT_FOUND: only those packages which have not been found which have the type RUNTIME

       

       If a FILENAME is given, the information is printed into this file.  If
       APPEND is used, it is appended to this file, otherwise the file is
       overwritten if it already existed.  If the VAR option is used, the
       information is "printed" into the specified variable.  If FILENAME is
       not used, the information is printed to the terminal.  Using the
       DESCRIPTION option a description or headline can be set which will be
       printed above the actual content.  If INCLUDE_QUIET_PACKAGES is given,
       packages which have been searched with find_package(...  QUIET) will
       also be listed.  By default they are skipped.  If
       FATAL_ON_MISSING_REQUIRED_PACKAGES is given, CMake will abort if a
       package which is marked as REQUIRED has not been found.

       Example 1, append everything to a file:

          feature_summary(WHAT ALL
                          FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND)

       

       Example 2, print the enabled features into the variable
       enabledFeaturesText, including QUIET packages:

          feature_summary(WHAT ENABLED_FEATURES
                          INCLUDE_QUIET_PACKAGES
                          DESCRIPTION "Enabled Features:"
                          VAR enabledFeaturesText)
          message(STATUS "${enabledFeaturesText}")

       

       

           SET_PACKAGE_PROPERTIES(<name> PROPERTIES [ URL <url> ]
                                                    [ DESCRIPTION <description> ]
                                                    [ TYPE (RUNTIME|OPTIONAL|RECOMMENDED|REQUIRED) ]
                                                    [ PURPOSE <purpose> ]
                                 )

       

       Use this macro to set up information about the named package, which
       can then be displayed via FEATURE_SUMMARY().  This can be done either
       directly in the Find-module or in the project which uses the module
       after the find_package() call.  The features for which information can
       be set are added automatically by the find_package() command.

       URL: this should be the homepage of the package, or something similar.
       Ideally this is set already directly in the Find-module.

       DESCRIPTION: A short description what that package is, at most one
       sentence.  Ideally this is set already directly in the Find-module.

       TYPE: What type of dependency has the using project on that package.
       Default is OPTIONAL.  In this case it is a package which can be used
       by the project when available at buildtime, but it also work without.
       RECOMMENDED is similar to OPTIONAL, i.e.  the project will build if
       the package is not present, but the functionality of the resulting
       binaries will be severly limited.  If a REQUIRED package is not
       available at buildtime, the project may not even build.  This can be
       combined with the FATAL_ON_MISSING_REQUIRED_PACKAGES argument for
       feature_summary().  Last, a RUNTIME package is a package which is
       actually not used at all during the build, but which is required for
       actually running the resulting binaries.  So if such a package is
       missing, the project can still be built, but it may not work later on.
       If set_package_properties() is called multiple times for the same
       package with different TYPEs, the TYPE is only changed to higher TYPEs
       ( RUNTIME < OPTIONAL < RECOMMENDED < REQUIRED ), lower TYPEs are
       ignored.  The TYPE property is project-specific, so it cannot be set
       by the Find-module, but must be set in the project.

       PURPOSE: This describes which features this package enables in the
       project, i.e.  it tells the user what functionality he gets in the
       resulting binaries.  If set_package_properties() is called multiple
       times for a package, all PURPOSE properties are appended to a list of
       purposes of the package in the project.  As the TYPE property, also
       the PURPOSE property is project-specific, so it cannot be set by the
       Find-module, but must be set in the project.

       

       Example for setting the info for a package:

          find_package(LibXml2)
          set_package_properties(LibXml2 PROPERTIES DESCRIPTION "A XML processing library."
                                                    URL "http://xmlsoft.org/")

       

          set_package_properties(LibXml2 PROPERTIES TYPE RECOMMENDED
                                                    PURPOSE "Enables HTML-import in MyWordProcessor")
          ...
          set_package_properties(LibXml2 PROPERTIES TYPE OPTIONAL
                                                    PURPOSE "Enables odt-export in MyWordProcessor")

       

          find_package(DBUS)
          set_package_properties(DBUS PROPERTIES TYPE RUNTIME
                                                    PURPOSE "Necessary to disable the screensaver during a presentation" )

       

           ADD_FEATURE_INFO(<name> <enabled> <description>)

       Use this macro to add information about a feature with the given
       <name>.  <enabled> contains whether this feature is enabled or not,
       <description> is a text describing the feature.  The information can
       be displayed using feature_summary() for ENABLED_FEATURES and
       DISABLED_FEATURES respectively.

       Example for setting the info for a feature:

          option(WITH_FOO "Help for foo" ON)
          add_feature_info(Foo WITH_FOO "The Foo feature provides very cool stuff.")

       

       

       The following macros are provided for compatibility with previous
       CMake versions:

           SET_PACKAGE_INFO(<name> <description> [<url> [<purpose>] ] )

       Use this macro to set up information about the named package, which
       can then be displayed via FEATURE_SUMMARY().  This can be done either
       directly in the Find-module or in the project which uses the module
       after the find_package() call.  The features for which information can
       be set are added automatically by the find_package() command.

           PRINT_ENABLED_FEATURES()

       Does the same as FEATURE_SUMMARY(WHAT ENABLED_FEATURES DESCRIPTION
       "Enabled features:")

           PRINT_DISABLED_FEATURES()

       Does the same as FEATURE_SUMMARY(WHAT DISABLED_FEATURES DESCRIPTION
       "Disabled features:")

           SET_FEATURE_INFO(<name> <description> [<url>] )

       Does the same as SET_PACKAGE_INFO(<name> <description> <url> )

       Locate AVIFILE library and include paths

       AVIFILE (http://avifile.sourceforge.net/)is a set of libraries for
       i386 machines to use various AVI codecs.  Support is limited beyond
       Linux.  Windows provides native AVI support, and so doesn't need this
       library.  This module defines

         AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
         AVIFILE_LIBRARIES, the libraries to link against
         AVIFILE_DEFINITIONS, definitions to use when compiling

  FindArmadillo
       Find Armadillo

       Find the Armadillo C++ library

       Using Armadillo:

         find_package(Armadillo REQUIRED)
         include_directories(${ARMADILLO_INCLUDE_DIRS})
         add_executable(foo foo.cc)
         target_link_libraries(foo ${ARMADILLO_LIBRARIES})

       This module sets the following variables:

  FindBISON
       Find bison executable and provides macros to generate custom build
       rules

       The module defines the following variables:

         BISON_EXECUTABLE - path to the bison program
         BISON_VERSION - version of bison
         BISON_FOUND - true if the program was found

       

       The minimum required version of bison can be specified using the
       standard CMake syntax, e.g.  find_package(BISON 2.1.3)

       If bison is found, the module defines the macros:

         BISON_TARGET(<Name> <YaccInput> <CodeOutput> [VERBOSE <file>]
                     [COMPILE_FLAGS <string>])

       which will create a custom rule to generate a parser.  <YaccInput> is
       the path to a yacc file.  <CodeOutput> is the name of the source file
       generated by bison.  A header file is also be generated, and contains
       the token list.  If COMPILE_FLAGS option is specified, the next
       parameter is added in the bison command line.  if VERBOSE option is
       specified, <file> is created and contains verbose descriptions of the
       grammar and parser.  The macro defines a set of variables:

         BISON_${Name}_DEFINED - true is the macro ran successfully
         BISON_${Name}_INPUT - The input source file, an alias for <YaccInput>
         BISON_${Name}_OUTPUT_SOURCE - The source file generated by bison
         BISON_${Name}_OUTPUT_HEADER - The header file generated by bison
         BISON_${Name}_OUTPUTS - The sources files generated by bison
         BISON_${Name}_COMPILE_FLAGS - Options used in the bison command line

       

         ====================================================================

          find_package(BISON)
          BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
          add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS})
         ====================================================================


  FindBLAS
       Find BLAS library

       This module finds an installed fortran library that implements the
       BLAS linear-algebra interface (see http://www.netlib.org/blas/).  The
       list of libraries searched for is taken from the autoconf macro file,
       acx_blas.m4 (distributed at
       http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).

       This module sets the following variables:

         BLAS_FOUND - set to true if a library implementing the BLAS interface
           is found
         BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
           and -L).
         BLAS_LIBRARIES - uncached list of libraries (using full path name) to
           link against to use BLAS
         BLAS95_LIBRARIES - uncached list of libraries (using full path name)
           to link against to use BLAS95 interface
         BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
           is found
         BLA_STATIC  if set on this determines what kind of linkage we do (static)
         BLA_VENDOR  if set checks only the specified vendor, if not set checks
            all the possibilities
         BLA_F95     if set on tries to find the f95 interfaces for BLAS/LAPACK

       C/CXX should be enabled to use Intel mkl

  FindBZip2
       Try to find BZip2

       Once done this will define

         BZIP2_FOUND - system has BZip2
         BZIP2_INCLUDE_DIR - the BZip2 include directory
         BZIP2_LIBRARIES - Link these to use BZip2
         BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_
         BZIP2_VERSION_STRING - the version of BZip2 found (since CMake 2.8.8)


  FindBoost
       Find Boost include dirs and libraries

       Use this module by invoking find_package with the form:

         find_package(Boost
           [version] [EXACT]      # Minimum or EXACT version e.g. 1.36.0
           [REQUIRED]             # Fail with error if Boost is not found
           [COMPONENTS <libs>...] # Boost libraries by their canonical name
           )                      # e.g. "date_time" for "libboost_date_time"

       This module finds headers and requested component libraries OR a CMake
       package configuration file provided by a "Boost CMake" build.  For the
       latter case skip to the "Boost CMake" section below.  For the former
       case results are reported in variables:

         Boost_FOUND            - True if headers and requested libraries were found
         Boost_INCLUDE_DIRS     - Boost include directories
         Boost_LIBRARY_DIRS     - Link directories for Boost libraries
         Boost_LIBRARIES        - Boost component libraries to be linked
         Boost_<C>_FOUND        - True if component <C> was found (<C> is upper-case)
         Boost_<C>_LIBRARY      - Libraries to link for component <C> (may include
                                  target_link_libraries debug/optimized keywords)
         Boost_VERSION          - BOOST_VERSION value from boost/version.hpp
         Boost_LIB_VERSION      - Version string appended to library filenames
         Boost_MAJOR_VERSION    - Boost major version number (X in X.y.z)
         Boost_MINOR_VERSION    - Boost minor version number (Y in x.Y.z)
         Boost_SUBMINOR_VERSION - Boost subminor version number (Z in x.y.Z)
         Boost_LIB_DIAGNOSTIC_DEFINITIONS (Windows)
                                - Pass to add_definitions() to have diagnostic
                                  information about Boost's automatic linking
                                  displayed during compilation

       

       This module reads hints about search locations from variables:

         BOOST_ROOT             - Preferred installation prefix
          (or BOOSTROOT)
         BOOST_INCLUDEDIR       - Preferred include directory e.g. <prefix>/include
         BOOST_LIBRARYDIR       - Preferred library directory e.g. <prefix>/lib
         Boost_NO_SYSTEM_PATHS  - Set to ON to disable searching in locations not
                                  specified by these hint variables. Default is OFF.
         Boost_ADDITIONAL_VERSIONS
                                - List of Boost versions not known to this module
                                  (Boost install locations may contain the version)

       and saves search results persistently in CMake cache entries:

         Boost_INCLUDE_DIR         - Directory containing Boost headers
         Boost_LIBRARY_DIR         - Directory containing Boost libraries
         Boost_<C>_LIBRARY_DEBUG   - Component <C> library debug variant
         Boost_<C>_LIBRARY_RELEASE - Component <C> library release variant

       Users may set these hints or results as cache entries.  Projects
       should not read these entries directly but instead use the above
       result variables.  Note that some hint names start in upper-case
       "BOOST".  One may specify these as environment variables if they are
       not specified as CMake variables or cache entries.

       This module first searches for the Boost header files using the above
       hint variables (excluding BOOST_LIBRARYDIR) and saves the result in
       Boost_INCLUDE_DIR.  Then it searches for requested component libraries
       using the above hints (excluding BOOST_INCLUDEDIR and
       Boost_ADDITIONAL_VERSIONS), "lib" directories near Boost_INCLUDE_DIR,
       and the library name configuration settings below.  It saves the
       library directory in Boost_LIBRARY_DIR and individual library
       locations in Boost_<C>_LIBRARY_DEBUG and Boost_<C>_LIBRARY_RELEASE.
       When one changes settings used by previous searches in the same build
       tree (excluding environment variables) this module discards previous
       search results affected by the changes and searches again.

       Boost libraries come in many variants encoded in their file name.
       Users or projects may tell this module which variant to find by
       setting variables:

         Boost_USE_MULTITHREADED  - Set to OFF to use the non-multithreaded
                                    libraries ('mt' tag).  Default is ON.
         Boost_USE_STATIC_LIBS    - Set to ON to force the use of the static
                                    libraries.  Default is OFF.
         Boost_USE_STATIC_RUNTIME - Set to ON or OFF to specify whether to use
                                    libraries linked statically to the C++ runtime
                                    ('s' tag).  Default is platform dependent.
         Boost_USE_DEBUG_PYTHON   - Set to ON to use libraries compiled with a
                                    debug Python build ('y' tag). Default is OFF.
         Boost_USE_STLPORT        - Set to ON to use libraries compiled with
                                    STLPort ('p' tag).  Default is OFF.
         Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS
                                  - Set to ON to use libraries compiled with
                                    STLPort deprecated "native iostreams"
                                    ('n' tag).  Default is OFF.
         Boost_COMPILER           - Set to the compiler-specific library suffix
                                    (e.g. "-gcc43").  Default is auto-computed
                                    for the C++ compiler in use.
         Boost_THREADAPI          - Suffix for "thread" component library name,
                                    such as "pthread" or "win32".  Names with
                                    and without this suffix will both be tried.

       Other variables one may set to control this module are:

         Boost_DEBUG              - Set to ON to enable debug output from FindBoost.
                                    Please enable this before filing any bug report.
         Boost_DETAILED_FAILURE_MSG
                                  - Set to ON to add detailed information to the
                                    failure message even when the REQUIRED option
                                    is not given to the find_package call.
         Boost_REALPATH           - Set to ON to resolve symlinks for discovered
                                    libraries to assist with packaging.  For example,
                                    the "system" component library may be resolved to
                                    "/usr/lib/libboost_system.so.1.42.0" instead of
                                    "/usr/lib/libboost_system.so".  This does not
                                    affect linking and should not be enabled unless
                                    the user needs this information.

       On Visual Studio and Borland compilers Boost headers request automatic
       linking to corresponding libraries.  This requires matching libraries
       to be linked explicitly or available in the link library search path.
       In this case setting Boost_USE_STATIC_LIBS to OFF may not achieve
       dynamic linking.  Boost automatic linking typically requests static
       libraries with a few exceptions (such as Boost.Python).  Use

         add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})

       to ask Boost to report information about automatic linking requests.

       Example to find Boost headers only:

         find_package(Boost 1.36.0)
         if(Boost_FOUND)
           include_directories(${Boost_INCLUDE_DIRS})
           add_executable(foo foo.cc)
         endif()

       Example to find Boost headers and some libraries:

         set(Boost_USE_STATIC_LIBS        ON)
         set(Boost_USE_MULTITHREADED      ON)
         set(Boost_USE_STATIC_RUNTIME    OFF)
         find_package(Boost 1.36.0 COMPONENTS date_time filesystem system ...)
         if(Boost_FOUND)
           include_directories(${Boost_INCLUDE_DIRS})
           add_executable(foo foo.cc)
           target_link_libraries(foo ${Boost_LIBRARIES})
         endif()

       

       Boost CMake ----------------------------------------------------------

       If Boost was built using the boost-cmake project it provides a package
       configuration file for use with find_package's Config mode.  This
       module looks for the package configuration file called
       BoostConfig.cmake or boost-config.cmake and stores the result in cache
       entry "Boost_DIR".  If found, the package configuration file is loaded
       and this module returns with no further action.  See documentation of
       the Boost CMake package configuration for details on what it provides.

       Set Boost_NO_BOOST_CMAKE to ON to disable the search for boost-cmake.

  FindBullet
       Try to find the Bullet physics engine

       

         This module defines the following variables

       

         BULLET_FOUND - Was bullet found
         BULLET_INCLUDE_DIRS - the Bullet include directories
         BULLET_LIBRARIES - Link to this, by default it includes
                            all bullet components (Dynamics,
                            Collision, LinearMath, & SoftBody)

       

         This module accepts the following variables

       

         BULLET_ROOT - Can be set to bullet install path or Windows build path

       


  FindCABLE
       Find CABLE

       This module finds if CABLE is installed and determines where the
       include files and libraries are.  This code sets the following
       variables:

         CABLE             the path to the cable executable
         CABLE_TCL_LIBRARY the path to the Tcl wrapper library
         CABLE_INCLUDE_DIR the path to the include directory

       

       To build Tcl wrappers, you should add shared library and link it to
       ${CABLE_TCL_LIBRARY}.  You should also add ${CABLE_INCLUDE_DIR} as an
       include directory.

  FindCUDA
       Tools for building CUDA C files: libraries and build dependencies.

       This script locates the NVIDIA CUDA C tools.  It should work on linux,
       windows, and mac and should be reasonably up to date with CUDA C
       releases.

       This script makes use of the standard find_package arguments of
       <VERSION>, REQUIRED and QUIET.  CUDA_FOUND will report if an
       acceptable version of CUDA was found.

       The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if
       the prefix cannot be determined by the location of nvcc in the system
       path and REQUIRED is specified to find_package().  To use a different
       installed version of the toolkit set the environment variable
       CUDA_BIN_PATH before running cmake (e.g.
       CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default
       /usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring.  If
       you change the value of CUDA_TOOLKIT_ROOT_DIR, various components that
       depend on the path will be relocated.

       It might be necessary to set CUDA_TOOLKIT_ROOT_DIR manually on certain
       platforms, or to use a cuda runtime not installed in the default
       location.  In newer versions of the toolkit the cuda library is
       included with the graphics driver- be sure that the driver version
       matches what is needed by the cuda runtime version.

       The following variables affect the behavior of the macros in the
       script (in alphebetical order).  Note that any of these flags can be
       changed multiple times in the same directory before calling
       CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE, CUDA_COMPILE_PTX
       or CUDA_WRAP_SRCS.

         CUDA_64_BIT_DEVICE_CODE (Default matches host bit size)
         -- Set to ON to compile for 64 bit device code, OFF for 32 bit device code.
            Note that making this different from the host code when generating object
            or C files from CUDA code just won't work, because size_t gets defined by
            nvcc in the generated source.  If you compile to PTX and then load the
            file yourself, you can mix bit sizes between device and host.

       

         CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON)
         -- Set to ON if you want the custom build rule to be attached to the source
            file in Visual Studio.  Turn OFF if you add the same cuda file to multiple
            targets.

       

            This allows the user to build the target from the CUDA file; however, bad
            things can happen if the CUDA source file is added to multiple targets.
            When performing parallel builds it is possible for the custom build
            command to be run more than once and in parallel causing cryptic build
            errors.  VS runs the rules for every source file in the target, and a
            source can have only one rule no matter how many projects it is added to.
            When the rule is run from multiple targets race conditions can occur on
            the generated file.  Eventually everything will get built, but if the user
            is unaware of this behavior, there may be confusion.  It would be nice if
            this script could detect the reuse of source files across multiple targets
            and turn the option off for the user, but no good solution could be found.

       

         CUDA_BUILD_CUBIN (Default OFF)
         -- Set to ON to enable and extra compilation pass with the -cubin option in
            Device mode. The output is parsed and register, shared memory usage is
            printed during build.

       

         CUDA_BUILD_EMULATION (Default OFF for device mode)
         -- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files
            when CUDA_BUILD_EMULATION is TRUE.

       

         CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR)
         -- Set to the path you wish to have the generated files placed.  If it is
            blank output files will be placed in CMAKE_CURRENT_BINARY_DIR.
            Intermediate files will always be placed in
            CMAKE_CURRENT_BINARY_DIR/CMakeFiles.

       

         CUDA_HOST_COMPILATION_CPP (Default ON)
         -- Set to OFF for C compilation of host code.

       

         CUDA_HOST_COMPILER (Default CMAKE_C_COMPILER, $(VCInstallDir)/bin for VS)
         -- Set the host compiler to be used by nvcc.  Ignored if -ccbin or
            --compiler-bindir is already present in the CUDA_NVCC_FLAGS or
            CUDA_NVCC_FLAGS_<CONFIG> variables.  For Visual Studio targets
            $(VCInstallDir)/bin is a special value that expands out to the path when
            the command is run from withing VS.

       

         CUDA_NVCC_FLAGS
         CUDA_NVCC_FLAGS_<CONFIG>
         -- Additional NVCC command line arguments.  NOTE: multiple arguments must be
            semi-colon delimited (e.g. --compiler-options;-Wall)

       

         CUDA_PROPAGATE_HOST_FLAGS (Default ON)
         -- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration
            dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the
            host compiler through nvcc's -Xcompiler flag.  This helps make the
            generated host code match the rest of the system better.  Sometimes
            certain flags give nvcc problems, and this will help you turn the flag
            propagation off.  This does not affect the flags supplied directly to nvcc
            via CUDA_NVCC_FLAGS or through the OPTION flags specified through
            CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS.  Flags used for
            shared library compilation are not affected by this flag.

       

         CUDA_SEPARABLE_COMPILATION (Default OFF)
         -- If set this will enable separable compilation for all CUDA runtime object
            files.  If used outside of CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY
            (e.g. calling CUDA_WRAP_SRCS directly),
            CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME and
            CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS should be called.

       

         CUDA_VERBOSE_BUILD (Default OFF)
         -- Set to ON to see all the commands used when building the CUDA file.  When
            using a Makefile generator the value defaults to VERBOSE (run make
            VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will
            always print the output.

       

       The script creates the following macros (in alphebetical order):

         CUDA_ADD_CUFFT_TO_TARGET( cuda_target )
         -- Adds the cufft library to the target (can be any target).  Handles whether
            you are in emulation mode or not.

       

         CUDA_ADD_CUBLAS_TO_TARGET( cuda_target )
         -- Adds the cublas library to the target (can be any target).  Handles
            whether you are in emulation mode or not.

       

         CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ...
                              [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
         -- Creates an executable "cuda_target" which is made up of the files
            specified.  All of the non CUDA C files are compiled using the standard
            build rules specified by CMAKE and the cuda files are compiled to object
            files using nvcc and the host compiler.  In addition CUDA_INCLUDE_DIRS is
            added automatically to include_directories().  Some standard CMake target
            calls can be used on the target after calling this macro
            (e.g. set_target_properties and target_link_libraries), but setting
            properties that adjust compilation flags will not affect code compiled by
            nvcc.  Such flags should be modified before calling CUDA_ADD_EXECUTABLE,
            CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS.

       

         CUDA_ADD_LIBRARY( cuda_target file0 file1 ...
                           [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] )
         -- Same as CUDA_ADD_EXECUTABLE except that a library is created.

       

         CUDA_BUILD_CLEAN_TARGET()
         -- Creates a convience target that deletes all the dependency files
            generated.  You should make clean after running this target to ensure the
            dependency files get regenerated.

       

         CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE]
                       [OPTIONS ...] )
         -- Returns a list of generated files from the input source files to be used
            with ADD_LIBRARY or ADD_EXECUTABLE.

       

         CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] )
         -- Returns a list of PTX files generated from the input source files.

       

         CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME( output_file_var
                                                              cuda_target
                                                              object_files )
         -- Compute the name of the intermediate link file used for separable
            compilation.  This file name is typically passed into
            CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS.  output_file_var is produced
            based on cuda_target the list of objects files that need separable
            compilation as specified by object_files.  If the object_files list is
            empty, then output_file_var will be empty.  This function is called
            automatically for CUDA_ADD_LIBRARY and CUDA_ADD_EXECUTABLE.  Note that
            this is a function and not a macro.

       

         CUDA_INCLUDE_DIRECTORIES( path0 path1 ... )
         -- Sets the directories that should be passed to nvcc
            (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu
            files.

       

       

         CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS( output_file_var cuda_target
                                                  nvcc_flags object_files)

       

         -- Generates the link object required by separable compilation from the given
            object files.  This is called automatically for CUDA_ADD_EXECUTABLE and
            CUDA_ADD_LIBRARY, but can be called manually when using CUDA_WRAP_SRCS
            directly.  When called from CUDA_ADD_LIBRARY or CUDA_ADD_EXECUTABLE the
            nvcc_flags passed in are the same as the flags passed in via the OPTIONS
            argument.  The only nvcc flag added automatically is the bitness flag as
            specified by CUDA_64_BIT_DEVICE_CODE.  Note that this is a function
            instead of a macro.

       

         CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ...
                          [STATIC | SHARED | MODULE] [OPTIONS ...] )
         -- This is where all the magic happens.  CUDA_ADD_EXECUTABLE,
            CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this
            function under the hood.

       

            Given the list of files (file0 file1 ... fileN) this macro generates
            custom commands that generate either PTX or linkable objects (use "PTX" or
            "OBJ" for the format argument to switch).  Files that don't end with .cu
            or have the HEADER_FILE_ONLY property are ignored.

       

            The arguments passed in after OPTIONS are extra command line options to
            give to nvcc.  You can also specify per configuration options by
            specifying the name of the configuration followed by the options.  General
            options must preceed configuration specific options.  Not all
            configurations need to be specified, only the ones provided will be used.

       

               OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag"
               DEBUG -g
               RELEASE --use_fast_math
               RELWITHDEBINFO --use_fast_math;-g
               MINSIZEREL --use_fast_math

       

            For certain configurations (namely VS generating object files with
            CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will
            be produced for the given cuda file.  This is because when you add the
            cuda file to Visual Studio it knows that this file produces an object file
            and will link in the resulting object file automatically.

       

            This script will also generate a separate cmake script that is used at
            build time to invoke nvcc.  This is for several reasons.

       

              1. nvcc can return negative numbers as return values which confuses
              Visual Studio into thinking that the command succeeded.  The script now
              checks the error codes and produces errors when there was a problem.

       

              2. nvcc has been known to not delete incomplete results when it
              encounters problems.  This confuses build systems into thinking the
              target was generated when in fact an unusable file exists.  The script
              now deletes the output files if there was an error.

       

              3. By putting all the options that affect the build into a file and then
              make the build rule dependent on the file, the output files will be
              regenerated when the options change.

       

            This script also looks at optional arguments STATIC, SHARED, or MODULE to
            determine when to target the object compilation for a shared library.
            BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in
            CUDA_ADD_LIBRARY.  On some systems special flags are added for building
            objects intended for shared libraries.  A preprocessor macro,
            <target_name>_EXPORTS is defined when a shared library compilation is
            detected.

       

            Flags passed into add_definitions with -D or /D are passed along to nvcc.

       

       The script defines the following variables:

         CUDA_VERSION_MAJOR    -- The major version of cuda as reported by nvcc.
         CUDA_VERSION_MINOR    -- The minor version.
         CUDA_VERSION
         CUDA_VERSION_STRING   -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR

       

         CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set).
         CUDA_SDK_ROOT_DIR     -- Path to the CUDA SDK.  Use this to find files in the
                                  SDK.  This script will not directly support finding
                                  specific libraries or headers, as that isn't
                                  supported by NVIDIA.  If you want to change
                                  libraries when the path changes see the
                                  FindCUDA.cmake script for an example of how to clear
                                  these variables.  There are also examples of how to
                                  use the CUDA_SDK_ROOT_DIR to locate headers or
                                  libraries, if you so choose (at your own risk).
         CUDA_INCLUDE_DIRS     -- Include directory for cuda headers.  Added automatically
                                  for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY.
         CUDA_LIBRARIES        -- Cuda RT library.

              NOTE: In older versions of this Find Module,
              this variable controlled if the Python test
              generator was used instead of the Perl one,
              regardless of which scripting language the
              user had installed.

       MACROS for optional use by CMake users:

           CXXTEST_ADD_TEST(<test_name> <gen_source_file> <input_files_to_testgen...>)
              Creates a CxxTest runner and adds it to the CTest testing suite
              Parameters:
                  test_name               The name of the test
                  gen_source_file         The generated source filename to be
                                          generated by CxxTest

              #==============
              Example Usage:

       

                  find_package(CxxTest)
                  if(CXXTEST_FOUND)
                      include_directories(${CXXTEST_INCLUDE_DIR})
                      enable_testing()

       

                      CXXTEST_ADD_TEST(unittest_foo foo_test.cc
                                        ${CMAKE_CURRENT_SOURCE_DIR}/foo_test.h)
                      target_link_libraries(unittest_foo foo) # as needed
                  endif()

       

                     This will (if CxxTest is found):
                     1. Invoke the testgen executable to autogenerate foo_test.cc in the
                        binary tree from "foo_test.h" in the current source directory.
                     2. Create an executable and test called unittest_foo.

       

             #=============
             Example foo_test.h:

       

                 #include <cxxtest/TestSuite.h>

       

                 class MyTestSuite : public CxxTest::TestSuite
                 {
                 public:
                    void testAddition( void )
                    {
                       TS_ASSERT( 1 + 1 > 1 );
                       TS_ASSERT_EQUALS( 1 + 1, 2 );
                    }
                 };

       


  FindCygwin
       this module looks for Cygwin

       


  FindDCMTK
       find DCMTK libraries and applications

       


  FindDart
       Find DART

       This module looks for the dart testing software and sets DART_ROOT to
       point to where it found it.


  FindDevIL
        

       This module locates the developer's image library.
       http://openil.sourceforge.net/

       This module sets:

          IL_LIBRARIES -   the name of the IL library. These include the full path to
                           the core DevIL library. This one has to be linked into the
                           application.
          ILU_LIBRARIES -  the name of the ILU library. Again, the full path. This
                           library is for filters and effects, not actual loading. It
                           doesn't have to be linked if the functionality it provides
                           is not used.
          ILUT_LIBRARIES - the name of the ILUT library. Full path. This part of the
                           library interfaces with OpenGL. It is not strictly needed
                           in applications.
          IL_INCLUDE_DIR - where to find the il.h, ilu.h and ilut.h files.
          IL_FOUND -       this is set to TRUE if all the above variables were set.
                           This will be set to false if ILU or ILUT are not found,
                           even if they are not needed. In most systems, if one
                           library is found all the others are as well. That's the
                           way the DevIL developers release it.


  FindDoxygen
       This module looks for Doxygen and the path to Graphviz's dot

       Doxygen is a documentation generation tool.  Please see
       http://www.doxygen.org

       This module accepts the following optional variables:

          DOXYGEN_SKIP_DOT       = If true this module will skip trying to find Dot
                                   (an optional component often used by Doxygen)

       

       This modules defines the following variables:

          DOXYGEN_EXECUTABLE     = The path to the doxygen command.
          DOXYGEN_FOUND          = Was Doxygen found or not?
          DOXYGEN_VERSION        = The version reported by doxygen --version

       

          DOXYGEN_DOT_EXECUTABLE = The path to the dot program used by doxygen.
          DOXYGEN_DOT_FOUND      = Was Dot found or not?
          DOXYGEN_DOT_PATH       = The path to dot not including the executable

       

       


  FindEXPAT
       Find expat

       Find the native EXPAT headers and libraries.

         EXPAT_INCLUDE_DIRS - where to find expat.h, etc.
         EXPAT_LIBRARIES    - List of libraries when using expat.
         EXPAT_FOUND        - True if expat found.


  FindFLEX
       Find flex executable and provides a macro to generate custom build
       rules

       

       The module defines the following variables:

         FLEX_FOUND - true is flex executable is found
         FLEX_EXECUTABLE - the path to the flex executable
         FLEX_VERSION - the version of flex
         FLEX_LIBRARIES - The flex libraries
         FLEX_INCLUDE_DIRS - The path to the flex headers

       

       The minimum required version of flex can be specified using the
       standard syntax, e.g.  find_package(FLEX 2.5.13)

       

       If flex is found on the system, the module provides the macro:

         FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])

       which creates a custom command to generate the <FlexOutput> file from
       the <FlexInput> file.  If COMPILE_FLAGS option is specified, the next
       parameter is added to the flex command line.  Name is an alias used to
       get details of this custom command.  Indeed the macro defines the
       following variables:

         FLEX_${Name}_DEFINED - true is the macro ran successfully
         FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an
         alias for FlexOutput
         FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}

       

       Flex scanners oftenly use tokens defined by Bison: the code generated
       by Flex depends of the header generated by Bison.  This module also
       defines a macro:

         ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)

       which adds the required dependency between a scanner and a parser
       where <FlexTarget> and <BisonTarget> are the first parameters of
       respectively FLEX_TARGET and BISON_TARGET macros.

         ====================================================================
         Example:

       

          find_package(BISON)
          find_package(FLEX)

       

          BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp)
          FLEX_TARGET(MyScanner lexer.l  ${CMAKE_CURRENT_BINARY_DIR}/lexer.cpp)
          ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)

       

          include_directories(${CMAKE_CURRENT_BINARY_DIR})
          add_executable(Foo
             Foo.cc
             ${BISON_MyParser_OUTPUTS}
             ${FLEX_MyScanner_OUTPUTS}
          )
         ====================================================================

                       The root directory of the gtest install prefix

       

          GTEST_MSVC_SEARCH - If compiling with MSVC, this variable can be set to
                              "MD" or "MT" to enable searching a GTest build tree
                              (defaults: "MD")

       

       Example Usage:

           enable_testing()
           find_package(GTest REQUIRED)
           include_directories(${GTEST_INCLUDE_DIRS})

       

           add_executable(foo foo.cc)
           target_link_libraries(foo ${GTEST_BOTH_LIBRARIES})

       

           add_test(AllTestsInFoo foo)

       

       

       If you would like each Google test to show up in CTest as a test you
       may use the following macro.  NOTE: It will slow down your tests by
       running an executable for each test and test fixture.  You will also
       have to rerun CMake after adding or removing tests or test fixtures.

       GTEST_ADD_TESTS(executable extra_args ARGN)

           executable = The path to the test executable
           extra_args = Pass a list of extra arguments to be passed to
                        executable enclosed in quotes (or "" for none)
           ARGN =       A list of source files to search for tests & test
                        fixtures.

       

         Example:
            set(FooTestArgs --foo 1 --bar 2)
            add_executable(FooTest FooUnitTest.cc)
            GTEST_ADD_TESTS(FooTest "${FooTestArgs}" FooUnitTest.cc)

         GETTEXT_MSGMERGE_EXECUTABLE: the full path to the msgmerge tool.
         GETTEXT_MSGFMT_EXECUTABLE: the full path to the msgfmt tool.
         GETTEXT_FOUND: True if gettext has been found.
         GETTEXT_VERSION_STRING: the version of gettext found (since CMake 2.8.8)

       

       Additionally it provides the following macros:
       GETTEXT_CREATE_TRANSLATIONS ( outputFile [ALL] file1 ...  fileN )

           This will create a target "translations" which will convert the
           given input po files into the binary output mo file. If the
           ALL option is used, the translations will also be created when
           building the default target.

       GETTEXT_PROCESS_POT( <potfile> [ALL] [INSTALL_DESTINATION <destdir>]
       LANGUAGES <lang1> <lang2> ...  )

            Process the given pot file to mo files.
            If INSTALL_DESTINATION is given then automatically install rules will be created,
            the language subdirectory will be taken into account (by default use share/locale/).
            If ALL is specified, the pot file is processed when building the all traget.
            It creates a custom target "potfile".

       GETTEXT_PROCESS_PO_FILES( <lang> [ALL] [INSTALL_DESTINATION <dir>]
       PO_FILES <po1> <po2> ...  )

            Process the given po files to mo files for the given language.
            If INSTALL_DESTINATION is given then automatically install rules will be created,
            the language subdirectory will be taken into account (by default use share/locale/).
            If ALL is specified, the po files are processed when building the all traget.
            It creates a custom target "pofiles".

          GIT_FOUND - true if the command line client was found
          GIT_VERSION_STRING - the version of git found (since CMake 2.8.8)

       Example usage:

          find_package(Git)
          if(GIT_FOUND)
            message("git found: ${GIT_EXECUTABLE}")
          endif()


  FindGnuTLS
       Try to find the GNU Transport Layer Security library (gnutls)

         GNUTLS_INCLUDE_DIR - The gnutls include directory
         GNUTLS_LIBRARIES - The libraries needed to use gnutls
         GNUTLS_DEFINITIONS - Compiler switches required for using gnutls


  FindGnuplot
       this module looks for gnuplot

         GNUPLOT_EXECUTABLE - the Gnuplot executable
         GNUPLOT_VERSION_STRING - the version of Gnuplot found (since CMake 2.8.8)

       

       GNUPLOT_VERSION_STRING will not work for old versions like 3.7.1.

  FindHDF5
       Find HDF5, a library for reading and writing self describing array
       data.

       

       This module invokes the HDF5 wrapper compiler that should be installed
       alongside HDF5.  Depending upon the HDF5 Configuration, the wrapper
       compiler is called either h5cc or h5pcc.  If this succeeds, the module
       will then call the compiler with the -show argument to see what flags
       are used when compiling an HDF5 client application.

       The module will optionally accept the COMPONENTS argument.  If no
       COMPONENTS are specified, then the find module will default to finding
       only the HDF5 C library.  If one or more COMPONENTS are specified, the
       module will attempt to find the language bindings for the specified
       components.  The only valid components are C, CXX, Fortran, HL, and
       Fortran_HL.  If the COMPONENTS argument is not given, the module will
       attempt to find only the C bindings.

       On UNIX systems, this module will read the variable
       HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a
       static link to a dynamic link for HDF5 and all of it's dependencies.
       To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES
       variable is set before the call to find_package.

       To provide the module with a hint about where to find your HDF5
       installation, you can set the environment variable HDF5_ROOT.  The
       Find module will then look in this path when searching for HDF5
       executables, paths, and libraries.

       In addition to finding the includes and libraries required to compile
       an HDF5 client application, this module also makes an effort to find
       tools that come with the HDF5 distribution that may be useful for
       regression testing.

       This module will define the following variables:

         HDF5_INCLUDE_DIRS - Location of the hdf5 includes
         HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated)
         HDF5_DEFINITIONS - Required compiler definitions for HDF5

         HDF5_HL_LIBRARIES - Required libraries for the HDF5 high level API
         HDF5_Fortran_HL_LIBRARIES - Required libraries for the high level Fortran
                                     bindings.
         HDF5_LIBRARIES - Required libraries for all requested bindings
         HDF5_FOUND - true if HDF5 was found on the system
         HDF5_LIBRARY_DIRS - the full set of library directories
         HDF5_IS_PARALLEL - Whether or not HDF5 was found with parallel IO support
         HDF5_C_COMPILER_EXECUTABLE - the path to the HDF5 C wrapper compiler
         HDF5_CXX_COMPILER_EXECUTABLE - the path to the HDF5 C++ wrapper compiler
         HDF5_Fortran_COMPILER_EXECUTABLE - the path to the HDF5 Fortran wrapper compiler
         HDF5_DIFF_EXECUTABLE - the path to the HDF5 dataset comparison tool


  FindHSPELL

          find_package(Hg)
          if(HG_FOUND)
            message("hg found: ${HG_EXECUTABLE}")
          endif()

         ICOTOOL_VERSION_STRING: the version of icotool found.

       


  FindImageMagick
       Find the ImageMagick binary suite.

       This module will search for a set of ImageMagick tools specified as
       components in the FIND_PACKAGE call.  Typical components include, but
       are not limited to (future versions of ImageMagick might have
       additional components not listed here):

       It also adds the following macros (from KDE3Macros.cmake) SRCS_VAR is
       always the variable which contains the list of source files for your
       application or library.

       KDE3_AUTOMOC(file1 ...  fileN)

           Call this if you want to have automatic moc file handling.
           This means if you include "foo.moc" in the source file foo.cpp
           a moc file for the header foo.h will be created automatically.
           You can set the property SKIP_AUTOMAKE using set_source_files_properties()
           to exclude some files in the list from being processed.

       

       KDE3_ADD_MOC_FILES(SRCS_VAR file1 ...  fileN )

           If you don't use the KDE3_AUTOMOC() macro, for the files
           listed here moc files will be created (named "foo.moc.cpp")

       

       KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ...  headerN.h )

           Use this to generate DCOP skeletions from the listed headers.

       

       KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ...  headerN.h )

            Use this to generate DCOP stubs from the listed headers.

       

       KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ...  fileN.ui )

           Use this to add the Qt designer ui files to your application/library.

       

       KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ...  fileN.kcfgc )

           Use this to add KDE kconfig compiler files to your application/library.

       

       KDE3_INSTALL_LIBTOOL_FILE(target)

           This will create and install a simple libtool file for the given target.

       

       KDE3_ADD_EXECUTABLE(name file1 ...  fileN )

           Currently identical to add_executable(), may provide some advanced features in the future.

       

       KDE3_ADD_KPART(name [WITH_PREFIX] file1 ...  fileN )

           Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
           If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't.
           It creates and installs an appropriate libtool la-file.

       

       KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ...  fileN )

           Create a KDE application in the form of a module loadable via kdeinit.
           A library named kdeinit_<name> will be created and a small executable which links to it.

       

       The option KDE3_ENABLE_FINAL to enable all-in-one compilation is no
       longer supported.

         LIBXSLT_DEFINITIONS - Compiler switches required for using LibXslt
         LIBXSLT_VERSION_STRING - version of LibXslt found (since CMake 2.8.8)

       Additionally, the following two variables are set (but not required
       for using xslt):

         LIBXSLT_EXSLT_LIBRARIES - Link to these if you need to link against the exslt library
         LIBXSLT_XSLTPROC_EXECUTABLE - Contains the full path to the xsltproc executable if found


  FindLua50
        

       Locate Lua library This module defines

         LUA50_FOUND, if false, do not try to link to Lua

         LUA_INCLUDE_DIR, where to find lua.h and lualib.h (and probably lauxlib.h)

       

       Note that the expected include convention is

         #include "lua.h"

       and not

         #include <lua/lua.h>

         #include "lua.h"

       and not

         #include <lua/lua.h>

       This is because, the lua location is not standardized and may exist in
       locations other than lua/

         MPEG2_vo_LIBRARY, where to find the vo library.


  FindMPI
       Find a Message Passing Interface (MPI) implementation

       The Message Passing Interface (MPI) is a library used to write
       high-performance distributed-memory parallel applications, and is
       typically deployed on a cluster.  MPI is a standard interface (defined
       by the MPI forum) for which many implementations are available.  All
       of them have somewhat different include paths, libraries to link
       against, etc., and this module tries to smooth out those differences.

       === Variables ===

       This module will set the following variables per language in your
       project, where <lang> is one of C, CXX, or Fortran:

          MPI_<lang>_FOUND           TRUE if FindMPI found MPI flags for <lang>
          MPI_<lang>_COMPILER        MPI Compiler wrapper for <lang>
          MPI_<lang>_COMPILE_FLAGS   Compilation flags for MPI programs
          MPI_<lang>_INCLUDE_PATH    Include path(s) for MPI header
          MPI_<lang>_LINK_FLAGS      Linking flags for MPI programs
          MPI_<lang>_LIBRARIES       All libraries to link MPI programs against

       Additionally, FindMPI sets the following variables for running MPI
       programs from the command line:

          MPIEXEC                    Executable for running MPI programs
          MPIEXEC_NUMPROC_FLAG       Flag to pass to MPIEXEC before giving
                                     it the number of processors to run on
          MPIEXEC_PREFLAGS           Flags to pass to MPIEXEC directly
                                     before the executable to run.
          MPIEXEC_POSTFLAGS          Flags to pass to MPIEXEC after other flags

       === Usage ===

       To use this module, simply call FindMPI from a CMakeLists.txt file, or
       run find_package(MPI), then run CMake.  If you are happy with the
       auto- detected configuration for your language, then you're done.  If
       not, you have two options:

          1. Set MPI_<lang>_COMPILER to the MPI wrapper (mpicc, etc.) of your
             choice and reconfigure.  FindMPI will attempt to determine all the
             necessary variables using THAT compiler's compile and link flags.
          2. If this fails, or if your MPI implementation does not come with
             a compiler wrapper, then set both MPI_<lang>_LIBRARIES and
             MPI_<lang>_INCLUDE_PATH.  You may also set any other variables
             listed above, but these two are required.  This will circumvent
             autodetection entirely.

       When configuration is successful, MPI_<lang>_COMPILER will be set to
       the compiler wrapper for <lang>, if it was found.  MPI_<lang>_FOUND
       and other variables above will be set if any MPI implementation was
       found for <lang>, regardless of whether a compiler was found.

       When using MPIEXEC to execute MPI applications, you should typically
       use all of the MPIEXEC flags as follows:

          ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS
            ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS

       where PROCS is the number of processors on which to execute the
       program, EXECUTABLE is the MPI program, and ARGS are the arguments to
       pass to the MPI program.

       === Backward Compatibility ===

       For backward compatibility with older versions of FindMPI, these
       variables are set, but deprecated:

          MPI_FOUND           MPI_COMPILER        MPI_LIBRARY
          MPI_COMPILE_FLAGS   MPI_INCLUDE_PATH    MPI_EXTRA_LIBRARY
          MPI_LINK_FLAGS      MPI_LIBRARIES

       In new projects, please use the MPI_<lang>_XXX equivalents.

  FindMatlab
       this module looks for Matlab

       Defines:

         MATLAB_INCLUDE_DIR: include path for mex.h, engine.h
         MATLAB_LIBRARIES:   required libraries: libmex, etc
         MATLAB_MEX_LIBRARY: path to libmex.lib
         MATLAB_MX_LIBRARY:  path to libmx.lib
         MATLAB_ENG_LIBRARY: path to libeng.lib


  FindMotif
       Try to find Motif (or lesstif)

       Once done this will define:

         MOTIF_FOUND        - system has MOTIF
         MOTIF_INCLUDE_DIR  - include paths to use Motif
         MOTIF_LIBRARIES    - Link these to use Motif


  FindOpenAL
        

       Locate OpenAL This module defines OPENAL_LIBRARY OPENAL_FOUND, if
       false, do not try to link to OpenAL OPENAL_INCLUDE_DIR, where to find
       the headers

       $OPENALDIR is an environment variable that would correspond to the
       ./configure --prefix=$OPENALDIR used in building OpenAL.

       Created by Eric Wing.  This was influenced by the FindSDL.cmake
       module.

  FindOpenGL
       Try to find OpenGL

       Once done this will define

         OPENGL_FOUND        - system has OpenGL
         OPENGL_XMESA_FOUND  - system has XMESA
         OPENGL_GLU_FOUND    - system has GLU
         OPENGL_INCLUDE_DIR  - the GL include directory
         OPENGL_LIBRARIES    - Link these to use OpenGL and GLU

       

       If you want to use just GL you can use these values

         OPENGL_gl_LIBRARY   - Path to OpenGL Library
         OPENGL_glu_LIBRARY  - Path to GLU Library

       

       On OSX default to using the framework version of opengl People will
       have to change the cache values of OPENGL_glu_LIBRARY and
       OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX

  FindOpenMP
       Finds OpenMP support

       This module can be used to detect OpenMP support in a compiler.  If
       the compiler supports OpenMP, the flags required to compile with
       OpenMP support are returned in variables for the different languages.
       The variables may be empty if the compiler does not need a special
       flag to support OpenMP.

       The following variables are set:

          OpenMP_C_FLAGS - flags to add to the C compiler for OpenMP support
          OpenMP_CXX_FLAGS - flags to add to the CXX compiler for OpenMP support
          OPENMP_FOUND - true if openmp is detected

       

       Supported compilers can be found at
       http://openmp.org/wp/openmp-compilers/

  FindOpenSSL
       Try to find the OpenSSL encryption library

       Once done this will define

         OPENSSL_ROOT_DIR - Set this variable to the root installation of OpenSSL

       

       Read-Only variables:

         OPENSSL_FOUND - system has the OpenSSL library
         OPENSSL_INCLUDE_DIR - the OpenSSL include directory
         OPENSSL_LIBRARIES - The libraries needed to use OpenSSL
         OPENSSL_VERSION - This is set to $major.$minor.$revision$path (eg. 0.9.8s)


  FindOpenSceneGraph
       Find OpenSceneGraph

       This module searches for the OpenSceneGraph core "osg" library as well
       as OpenThreads, and whatever additional COMPONENTS (nodekits) that you
       specify.

           See http://www.openscenegraph.org

       

       NOTE: To use this module effectively you must either require CMake >=
       2.6.3 with cmake_minimum_required(VERSION 2.6.3) or download and place
       FindOpenThreads.cmake, Findosg_functions.cmake, Findosg.cmake, and
       Find<etc>.cmake files into your CMAKE_MODULE_PATH.

       ==================================

       This module accepts the following variables (note mixed case)

           OpenSceneGraph_DEBUG - Enable debugging output

       

           OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced
                                             automatically

       

       The following environment variables are also respected for finding the
       OSG and it's various components.  CMAKE_PREFIX_PATH can also be used
       for this (see find_library() CMake documentation).

           <MODULE>_DIR (where MODULE is of the form "OSGVOLUME" and there is a FindosgVolume.cmake file)
           OSG_DIR
           OSGDIR
           OSG_ROOT

       

       [CMake 2.8.10]: The CMake variable OSG_DIR can now be used as well to
       influence detection, instead of needing to specify an environment
       variable.

       This module defines the following output variables:

           OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?

       

           OPENSCENEGRAPH_VERSION - The version of the OSG which was found

       

           OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers

       

           OPENSCENEGRAPH_LIBRARIES - The OSG libraries

       

       ================================== Example Usage:

         find_package(OpenSceneGraph 2.0.0 REQUIRED osgDB osgUtil)
             # libOpenThreads & libosg automatically searched
         include_directories(${OPENSCENEGRAPH_INCLUDE_DIRS})

       

         add_executable(foo foo.cc)
         target_link_libraries(foo ${OPENSCENEGRAPH_LIBRARIES})

       


  FindOpenThreads
        

       OpenThreads is a C++ based threading library.  Its largest userbase
       seems to OpenSceneGraph so you might notice I accept OSGDIR as an
       environment path.  I consider this part of the Findosg* suite used to
       find OpenSceneGraph components.  Each component is separate and you
       must opt in to each module.

       Locate OpenThreads This module defines OPENTHREADS_LIBRARY
       OPENTHREADS_FOUND, if false, do not try to link to OpenThreads
       OPENTHREADS_INCLUDE_DIR, where to find the headers

       $OPENTHREADS_DIR is an environment variable that would correspond to
       the ./configure --prefix=$OPENTHREADS_DIR used in building osg.

       [CMake 2.8.10]: The CMake variables OPENTHREADS_DIR or OSG_DIR can now
       be used as well to influence detection, instead of needing to specify
       an environment variable.

       Created by Eric Wing.

  FindPHP4
       Find PHP4

       This module finds if PHP4 is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PHP4_INCLUDE_PATH       = path to where php.h can be found
         PHP4_EXECUTABLE         = full path to the php4 binary

       


  FindPNG
       Find the native PNG includes and library

       

       This module searches libpng, the library for working with PNG images.

       It defines the following variables

         PNG_INCLUDE_DIRS, where to find png.h, etc.
         PNG_LIBRARIES, the libraries to link against to use PNG.
         PNG_DEFINITIONS - You should add_definitons(${PNG_DEFINITIONS}) before compiling code that includes png library files.
         PNG_FOUND, If false, do not try to use PNG.
         PNG_VERSION_STRING - the version of the PNG library found (since CMake 2.8.8)

       Also defined, but not for general use are

         PNG_LIBRARY, where to find the PNG library.

       For backward compatiblity the variable PNG_INCLUDE_DIR is also set.
       It has the same value as PNG_INCLUDE_DIRS.

       Since PNG depends on the ZLib compression library, none of the above
       will be defined unless ZLib can be found.

  FindPackageHandleStandardArgs
        

       FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ...  )

       This function is intended to be used in FindXXX.cmake modules files.
       It handles the REQUIRED, QUIET and version-related arguments to
       find_package().  It also sets the <packagename>_FOUND variable.  The
       package is considered found if all variables <var1>...  listed contain
       valid results, e.g.  valid filepaths.

       There are two modes of this function.  The first argument in both
       modes is the name of the Find-module where it is called (in original
       casing).

       The first simple mode looks like this:

           FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )

       If the variables <var1> to <varN> are all valid, then
       <UPPERCASED_NAME>_FOUND will be set to TRUE.  If DEFAULT_MSG is given
       as second argument, then the function will generate itself useful
       success and error messages.  You can also supply a custom error
       message for the failure case.  This is not recommended.

       The second mode is more powerful and also supports version checking:

           FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME [FOUND_VAR <resultVar>]
                                                  [REQUIRED_VARS <var1>...<varN>]
                                                  [VERSION_VAR   <versionvar>]
                                                  [HANDLE_COMPONENTS]
                                                  [CONFIG_MODE]
                                                  [FAIL_MESSAGE "Custom failure message"] )

       

       In this mode, the name of the result-variable can be set either to
       either <UPPERCASED_NAME>_FOUND or <OriginalCase_Name>_FOUND using the
       FOUND_VAR option.  Other names for the result-variable are not
       allowed.  So for a Find-module named FindFooBar.cmake, the two
       possible names are FooBar_FOUND and FOOBAR_FOUND.  It is recommended
       to use the original case version.  If the FOUND_VAR option is not
       used, the default is <UPPERCASED_NAME>_FOUND.

       As in the simple mode, if <var1> through <varN> are all valid,
       <packagename>_FOUND will be set to TRUE.  After REQUIRED_VARS the
       variables which are required for this package are listed.  Following
       VERSION_VAR the name of the variable can be specified which holds the
       version of the package which has been found.  If this is done, this
       version will be checked against the (potentially) specified required
       version used in the find_package() call.  The EXACT keyword is also
       handled.  The default messages include information about the required
       version and the version which has been actually found, both if the
       version is ok or not.  If the package supports components, use the
       HANDLE_COMPONENTS option to enable handling them.  In this case,
       find_package_handle_standard_args() will report which components have
       been found and which are missing, and the <packagename>_FOUND variable
       will be set to FALSE if any of the required components (i.e.  not the
       ones listed after OPTIONAL_COMPONENTS) are missing.  Use the option
       CONFIG_MODE if your FindXXX.cmake module is a wrapper for a
       find_package(...  NO_MODULE) call.  In this case VERSION_VAR will be
       set to <NAME>_VERSION and the macro will automatically check whether
       the Config module was found.  Via FAIL_MESSAGE a custom failure
       message can be specified, if this is not used, the default message
       will be displayed.

       Example for mode 1:

           find_package_handle_standard_args(LibXml2  DEFAULT_MSG  LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)

       

       LibXml2 is considered to be found, if both LIBXML2_LIBRARY and
       LIBXML2_INCLUDE_DIR are valid.  Then also LIBXML2_FOUND is set to
       TRUE.  If it is not found and REQUIRED was used, it fails with
       FATAL_ERROR, independent whether QUIET was used or not.  If it is
       found, success will be reported, including the content of <var1>.  On
       repeated Cmake runs, the same message won't be printed again.

       Example for mode 2:

           find_package_handle_standard_args(LibXslt FOUND_VAR LibXslt_FOUND
                                                    REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS
                                                    VERSION_VAR LibXslt_VERSION_STRING)

       In this case, LibXslt is considered to be found if the variable(s)
       listed after REQUIRED_VAR are all valid, i.e.  LibXslt_LIBRARIES and
       LibXslt_INCLUDE_DIRS in this case.  The result will then be stored in
       LibXslt_FOUND .  Also the version of LibXslt will be checked by using
       the version contained in LibXslt_VERSION_STRING.  Since no
       FAIL_MESSAGE is given, the default messages will be printed.

       Another example for mode 2:

           find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
           find_package_handle_standard_args(Automoc4  CONFIG_MODE)

       In this case, FindAutmoc4.cmake wraps a call to find_package(Automoc4
       NO_MODULE) and adds an additional search directory for automoc4.  Here
       the result will be stored in AUTOMOC4_FOUND.  The following
       FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper
       success/error message.

  FindPackageMessage
        

       FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")

       This macro is intended to be used in FindXXX.cmake modules files.  It
       will print a message once for each unique find result.  This is useful
       for telling the user where a package was found.  The first argument
       specifies the name (XXX) of the package.  The second argument
       specifies the message to display.  The third argument lists details
       about the find result so that if they change the message will be
       displayed again.  The macro also obeys the QUIET argument to the
       find_package command.

       Example:

         if(X11_FOUND)
           FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
             "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
         else()
          ...
         endif()

       Find Perl libraries

       This module finds if PERL is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PERLLIBS_FOUND    = True if perl.h & libperl were found
         PERL_INCLUDE_PATH = path to where perl.h is found
         PERL_LIBRARY      = path to libperl
         PERL_EXECUTABLE   = full path to the perl binary

       

       The minimum required version of Perl can be specified using the
       standard syntax, e.g.  find_package(PerlLibs 6.0)

         The following variables are also available if needed
         (introduced after CMake 2.6.4)

       

         PERL_SITESEARCH    = path to the sitesearch install dir
         PERL_SITELIB       = path to the sitelib install directory
         PERL_VENDORARCH    = path to the vendor arch install directory
         PERL_VENDORLIB     = path to the vendor lib install directory
         PERL_ARCHLIB       = path to the arch lib install directory
         PERL_PRIVLIB       = path to the priv lib install directory
         PERL_EXTRA_C_FLAGS = Compilation flags used to build perl

       


  FindPhysFS
        

       Locate PhysFS library This module defines PHYSFS_LIBRARY, the name of
       the library to link against PHYSFS_FOUND, if false, do not try to link
       to PHYSFS PHYSFS_INCLUDE_DIR, where to find physfs.h

       $PHYSFSDIR is an environment variable that would correspond to the
       ./configure --prefix=$PHYSFSDIR used in building PHYSFS.

       Created by Eric Wing.

  FindPike
       Find Pike

       This module finds if PIKE is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PIKE_INCLUDE_PATH       = path to where program.h is found
         PIKE_EXECUTABLE         = full path to the pike binary

       


  FindPkgConfig
       a pkg-config module for CMake

       

       Usage:

          pkg_check_modules(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
            checks for all the given modules

       

          pkg_search_module(<PREFIX> [REQUIRED] [QUIET] <MODULE> [<MODULE>]*)
            checks for given modules and uses the first working one

       

       When the 'REQUIRED' argument was set, macros will fail with an error
       when module(s) could not be found

       When the 'QUIET' argument is set, no status messages will be printed.

       It sets the following variables:

          PKG_CONFIG_FOUND          ... if pkg-config executable was found
          PKG_CONFIG_EXECUTABLE     ... pathname of the pkg-config program
          PKG_CONFIG_VERSION_STRING ... the version of the pkg-config program found
                                        (since CMake 2.8.8)

       

       For the following variables two sets of values exist; first one is the
       common one and has the given PREFIX.  The second set contains flags
       which are given out when pkgconfig was called with the '--static'
       option.

          <XPREFIX>_FOUND          ... set to 1 if module(s) exist
          <XPREFIX>_LIBRARIES      ... only the libraries (w/o the '-l')
          <XPREFIX>_LIBRARY_DIRS   ... the paths of the libraries (w/o the '-L')
          <XPREFIX>_LDFLAGS        ... all required linker flags
          <XPREFIX>_LDFLAGS_OTHER  ... all other linker flags
          <XPREFIX>_INCLUDE_DIRS   ... the '-I' preprocessor flags (w/o the '-I')
          <XPREFIX>_CFLAGS         ... all required cflags
          <XPREFIX>_CFLAGS_OTHER   ... the other compiler flags

       

          <XPREFIX> = <PREFIX>        for common case
          <XPREFIX> = <PREFIX>_STATIC for static linking

       

       There are some special variables whose prefix depends on the count of
       given modules.  When there is only one module, <PREFIX> stays
       unchanged.  When there are multiple modules, the prefix will be
       changed to <PREFIX>_<MODNAME>:

          <XPREFIX>_VERSION    ... version of the module
          <XPREFIX>_PREFIX     ... prefix-directory of the module
          <XPREFIX>_INCLUDEDIR ... include-dir of the module
          <XPREFIX>_LIBDIR     ... lib-dir of the module

       

          <XPREFIX> = <PREFIX>  when |MODULES| == 1, else
          <XPREFIX> = <PREFIX>_<MODNAME>

       

       A <MODULE> parameter can have the following formats:

          {MODNAME}            ... matches any version
          {MODNAME}>={VERSION} ... at least version <VERSION> is required
          {MODNAME}={VERSION}  ... exactly version <VERSION> is required
          {MODNAME}<={VERSION} ... modules must not be newer than <VERSION>

       

       Examples

          pkg_check_modules (GLIB2   glib-2.0)

       

          pkg_check_modules (GLIB2   glib-2.0>=2.10)
            requires at least version 2.10 of glib2 and defines e.g.
              GLIB2_VERSION=2.10.3

       

          pkg_check_modules (FOO     glib-2.0>=2.10 gtk+-2.0)
            requires both glib2 and gtk2, and defines e.g.
              FOO_glib-2.0_VERSION=2.10.3
              FOO_gtk+-2.0_VERSION=2.8.20

       

          pkg_check_modules (XRENDER REQUIRED xrender)
            defines e.g.:
              XRENDER_LIBRARIES=Xrender;X11
              XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp

       

          pkg_search_module (BAR     libxml-2.0 libxml2 libxml>=2)


  FindPostgreSQL
       Find the PostgreSQL installation.

       In Windows, we make the assumption that, if the PostgreSQL files are
       installed, the default directory will be C:\Program Files\PostgreSQL.

       This module defines

         PostgreSQL_LIBRARIES - the PostgreSQL libraries needed for linking
         PostgreSQL_INCLUDE_DIRS - the directories of the PostgreSQL headers
         PostgreSQL_VERSION_STRING - the version of PostgreSQL found (since CMake 2.8.8)


  FindProducer
        

       Though Producer isn't directly part of OpenSceneGraph, its primary
       user is OSG so I consider this part of the Findosg* suite used to find
       OpenSceneGraph components.  You'll notice that I accept OSGDIR as an
       environment path.

       Each component is separate and you must opt in to each module.  You
       must also opt into OpenGL (and OpenThreads?) as these modules won't do
       it for you.  This is to allow you control over your own system piece
       by piece in case you need to opt out of certain components or change
       the Find behavior for a particular module (perhaps because the default
       FindOpenGL.cmake module doesn't work with your system as an example).
       If you want to use a more convenient module that includes everything,
       use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake
       modules.

       Locate Producer This module defines PRODUCER_LIBRARY PRODUCER_FOUND,
       if false, do not try to link to Producer PRODUCER_INCLUDE_DIR, where
       to find the headers

       $PRODUCER_DIR is an environment variable that would correspond to the
       ./configure --prefix=$PRODUCER_DIR used in building osg.

       Created by Eric Wing.

  FindProtobuf
        

       Locate and configure the Google Protocol Buffers library.

       The following variables can be set and are optional:

          PROTOBUF_SRC_ROOT_FOLDER - When compiling with MSVC, if this cache variable is set
                                     the protobuf-default VS project build locations
                                     (vsprojects/Debug & vsprojects/Release) will be searched
                                     for libraries and binaries.

       

          PROTOBUF_IMPORT_DIRS     - List of additional directories to be searched for
                                     imported .proto files. (New in CMake 2.8.8)

       

       Defines the following variables:

          PROTOBUF_FOUND - Found the Google Protocol Buffers library (libprotobuf & header files)
          PROTOBUF_INCLUDE_DIRS - Include directories for Google Protocol Buffers
          PROTOBUF_LIBRARIES - The protobuf libraries

       [New in CMake 2.8.5]

          PROTOBUF_PROTOC_LIBRARIES - The protoc libraries
          PROTOBUF_LITE_LIBRARIES - The protobuf-lite libraries

       

       The following cache variables are also available to set or use:

          PROTOBUF_LIBRARY - The protobuf library
          PROTOBUF_PROTOC_LIBRARY   - The protoc library
          PROTOBUF_INCLUDE_DIR - The include directory for protocol buffers
          PROTOBUF_PROTOC_EXECUTABLE - The protoc compiler

       [New in CMake 2.8.5]

          PROTOBUF_LIBRARY_DEBUG - The protobuf library (debug)
          PROTOBUF_PROTOC_LIBRARY_DEBUG   - The protoc library (debug)
          PROTOBUF_LITE_LIBRARY - The protobuf lite library
          PROTOBUF_LITE_LIBRARY_DEBUG - The protobuf lite library (debug)

       

         ====================================================================
         Example:

       

          find_package(Protobuf REQUIRED)
          include_directories(${PROTOBUF_INCLUDE_DIRS})

       

          include_directories(${CMAKE_CURRENT_BINARY_DIR})
          PROTOBUF_GENERATE_CPP(PROTO_SRCS PROTO_HDRS foo.proto)
          add_executable(bar bar.cc ${PROTO_SRCS} ${PROTO_HDRS})
          target_link_libraries(bar ${PROTOBUF_LIBRARIES})

       

       NOTE: You may need to link against pthreads, depending

              on the platform.

       

       NOTE: The PROTOBUF_GENERATE_CPP macro & add_executable() or
       add_library()

              calls only work properly within the same directory.

  FindPythonInterp
       Find python interpreter

       This module finds if Python interpreter is installed and determines
       where the executables are.  This code sets the following variables:

         PYTHONINTERP_FOUND         - Was the Python executable found
         PYTHON_EXECUTABLE          - path to the Python interpreter

       

         PYTHON_VERSION_STRING      - Python version found e.g. 2.5.2
         PYTHON_VERSION_MAJOR       - Python major version found e.g. 2
         PYTHON_VERSION_MINOR       - Python minor version found e.g. 5
         PYTHON_VERSION_PATCH       - Python patch version found e.g. 2

       

       The Python_ADDITIONAL_VERSIONS variable can be used to specify a list
       of version numbers that should be taken into account when searching
       for Python.  You need to set this variable before calling
       find_package(PythonInterp).

  FindPythonLibs
       Find python libraries

       This module finds if Python is installed and determines where the
       include files and libraries are.  It also determines what the name of
       the library is.  This code sets the following variables:

         PYTHONLIBS_FOUND           - have the Python libs been found
         PYTHON_LIBRARIES           - path to the python library
         PYTHON_INCLUDE_PATH        - path to where Python.h is found (deprecated)
         PYTHON_INCLUDE_DIRS        - path to where Python.h is found
         PYTHON_DEBUG_LIBRARIES     - path to the debug library (deprecated)
         PYTHONLIBS_VERSION_STRING  - version of the Python libs found (since CMake 2.8.8)

       

       The Python_ADDITIONAL_VERSIONS variable can be used to specify a list
       of version numbers that should be taken into account when searching
       for Python.  You need to set this variable before calling
       find_package(PythonLibs).

       If you'd like to specify the installation of Python to use, you should
       modify the following cache variables:

         PYTHON_LIBRARY             - path to the python library
         PYTHON_INCLUDE_DIR         - path to where Python.h is found


  FindQt
       Searches for all installed versions of Qt.

       This should only be used if your project can work with multiple
       versions of Qt.  If not, you should just directly use FindQt4 or
       FindQt3.  If multiple versions of Qt are found on the machine, then
       The user must set the option DESIRED_QT_VERSION to the version they
       want to use.  If only one version of qt is found on the machine, then
       the DESIRED_QT_VERSION is set to that version and the matching FindQt3
       or FindQt4 module is included.  Once the user sets DESIRED_QT_VERSION,
       then the FindQt3 or FindQt4 module is included.

         QT_REQUIRED if this is set to TRUE then if CMake can
                     not find Qt4 or Qt3 an error is raised
                     and a message is sent to the user.

       

         DESIRED_QT_VERSION OPTION is created
         QT4_INSTALLED is set to TRUE if qt4 is found.
         QT3_INSTALLED is set to TRUE if qt3 is found.


  FindQt3
       Locate Qt include paths and libraries

       This module defines:

         QT_INCLUDE_DIR    - where to find qt.h, etc.
         QT_LIBRARIES      - the libraries to link against to use Qt.
         QT_DEFINITIONS    - definitions to use when
                             compiling code that uses Qt.
         QT_FOUND          - If false, don't try to use Qt.
         QT_VERSION_STRING - the version of Qt found

       

       If you need the multithreaded version of Qt, set QT_MT_REQUIRED to
       TRUE

       Also defined, but not for general use are:

         QT_MOC_EXECUTABLE, where to find the moc tool.
         QT_UIC_EXECUTABLE, where to find the uic tool.
         QT_QT_LIBRARY, where to find the Qt library.
         QT_QTMAIN_LIBRARY, where to find the qtmain
          library. This is only required by Qt3 on Windows.


  FindQt4
       Find Qt 4

       This module can be used to find Qt4.  The most important issue is that
       the Qt4 qmake is available via the system path.  This qmake is then
       used to detect basically everything else.  This module defines a
       number of key variables and macros.  The variable QT_USE_FILE is set
       which is the path to a CMake file that can be included to compile Qt 4
       applications and libraries.  It sets up the compilation environment
       for include directories, preprocessor defines and populates a
       QT_LIBRARIES variable.

       Typical usage could be something like:

          find_package(Qt4 4.4.3 REQUIRED QtCore QtGui QtXml)
          include(${QT_USE_FILE})
          add_executable(myexe main.cpp)
          target_link_libraries(myexe ${QT_LIBRARIES})

       

       The minimum required version can be specified using the standard
       find_package()-syntax (see example above).  For compatibility with
       older versions of FindQt4.cmake it is also possible to set the
       variable QT_MIN_VERSION to the minimum required version of Qt4 before
       the find_package(Qt4) command.  If both are used, the version used in
       the find_package() command overrides the one from QT_MIN_VERSION.

       When using the components argument, QT_USE_QT* variables are
       automatically set for the QT_USE_FILE to pick up.  If one wishes to
       manually set them, the available ones to set include:

                           QT_DONT_USE_QTCORE
                           QT_DONT_USE_QTGUI
                           QT_USE_QT3SUPPORT
                           QT_USE_QTASSISTANT
                           QT_USE_QAXCONTAINER
                           QT_USE_QAXSERVER
                           QT_USE_QTDESIGNER
                           QT_USE_QTMOTIF
                           QT_USE_QTMAIN
                           QT_USE_QTMULTIMEDIA
                           QT_USE_QTNETWORK
                           QT_USE_QTNSPLUGIN
                           QT_USE_QTOPENGL
                           QT_USE_QTSQL
                           QT_USE_QTXML
                           QT_USE_QTSVG
                           QT_USE_QTTEST
                           QT_USE_QTUITOOLS
                           QT_USE_QTDBUS
                           QT_USE_QTSCRIPT
                           QT_USE_QTASSISTANTCLIENT
                           QT_USE_QTHELP
                           QT_USE_QTWEBKIT
                           QT_USE_QTXMLPATTERNS
                           QT_USE_PHONON
                           QT_USE_QTSCRIPTTOOLS
                           QT_USE_QTDECLARATIVE

       

         QT_USE_IMPORTED_TARGETS
               If this variable is set to TRUE, FindQt4.cmake will create imported
               library targets for the various Qt libraries and set the
               library variables like QT_QTCORE_LIBRARY to point at these imported
               targets instead of the library file on disk. This provides much better
               handling of the release and debug versions of the Qt libraries and is
              also always backwards compatible, except for the case that dependencies
              of libraries are exported, these will then also list the names of the
              imported targets as dependency and not the file location on disk. This
              is much more flexible, but requires that FindQt4.cmake is executed before
              such an exported dependency file is processed.

       

              Note that if using IMPORTED targets, the qtmain.lib static library is
              automatically linked on Windows. To disable that globally, set the
              QT4_NO_LINK_QTMAIN variable before finding Qt4. To disable that for a
              particular executable, set the QT4_NO_LINK_QTMAIN target property to
              True on the executable.

       

         QT_INCLUDE_DIRS_NO_SYSTEM
               If this variable is set to TRUE, the Qt include directories
               in the QT_USE_FILE will NOT have the SYSTEM keyword set.

       

       There are also some files that need processing by some Qt tools such
       as moc and uic.  Listed below are macros that may be used to process
       those files.

         macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
               create moc code from a list of files containing Qt class with
               the Q_OBJECT declaration.  Per-directory preprocessor definitions
               are also added.  Options may be given to moc, such as those found
               when executing "moc -help".

       

         macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
               create code from a list of Qt designer ui files.
               Options may be given to uic, such as those found
               when executing "uic -help"

       

         macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
               create code from a list of Qt resource files.
               Options may be given to rcc, such as those found
               when executing "rcc -help"

       

         macro QT4_GENERATE_MOC(inputfile outputfile )
               creates a rule to run moc on infile and create outfile.
               Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
               because you need a custom filename for the moc file or something similar.

       

         macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
               The qt4_automoc macro is obsolete.  Use the CMAKE_AUTOMOC feature instead.
               This macro is still experimental.
               It can be used to have moc automatically handled.
               So if you have the files foo.h and foo.cpp, and in foo.h a
               a class uses the Q_OBJECT macro, moc has to run on it. If you don't
               want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
               #include "foo.moc"
               in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
               scan all listed files at cmake-time for such included moc files and if it finds
               them cause a rule to be generated to run moc at build time on the
               accompanying header file foo.h.
               If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.

       

               You should have a look on the AUTOMOC property for targets to achieve the same results.

       

         macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
               Create the interface header and implementation files with the
               given basename from the given interface xml file and add it to
               the list of sources.

       

               You can pass additional parameters to the qdbusxml2cpp call by setting
               properties on the input file:

       

               INCLUDE the given file will be included in the generate interface header

       

               CLASSNAME the generated class is named accordingly

       

               NO_NAMESPACE the generated class is not wrapped in a namespace

       

         macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
               Create the interface header and implementation files
               for all listed interface xml files.
               The basename will be automatically determined from the name of the xml file.

       

               The source file properties described for QT4_ADD_DBUS_INTERFACE also apply here.

       

         macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] [classname])
               create a dbus adaptor (header and implementation file) from the xml file
               describing the interface, and add it to the list of sources. The adaptor
               forwards the calls to a parent class, defined in parentheader and named
               parentclassname. The name of the generated files will be
               <basename>adaptor.{cpp,h} where basename defaults to the basename of the xml file.
               If <classname> is provided, then it will be used as the classname of the
               adaptor itself.

       

         macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...)
               generate the xml interface file from the given header.
               If the optional argument interfacename is omitted, the name of the
               interface file is constructed from the basename of the header with
               the suffix .xml appended.
               Options may be given to qdbuscpp2xml, such as those found when executing "qdbuscpp2xml --help"

       

         macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
                                       ts_files ... OPTIONS ...)
               out: qm_files
               in:  directories sources ts_files
               options: flags to pass to lupdate, such as -extensions to specify
               extensions for a directory scan.
               generates commands to create .ts (vie lupdate) and .qm
               (via lrelease) - files from directories and/or sources. The ts files are
               created and/or updated in the source tree (unless given with full paths).
               The qm files are generated in the build tree.
               Updating the translations can be done by adding the qm_files
               to the source list of your library/executable, so they are
               always updated, or by adding a custom target to control when
               they get updated/generated.

       

         macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
               out: qm_files
               in:  ts_files
               generates commands to create .qm from .ts - files. The generated
               filenames can be found in qm_files. The ts_files
               must exist and are not updated in any way.

       

       function QT4_USE_MODULES( target [link_type] modules...)

               This function is obsolete. Use target_link_libraries with IMPORTED targets instead.
               Make <target> use the <modules> from Qt. Using a Qt module means
               to link to the library, add the relevant include directories for the module,
               and add the relevant compiler defines for using the module.
               Modules are roughly equivalent to components of Qt4, so usage would be
               something like:
                qt4_use_modules(myexe Core Gui Declarative)
               to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument can
               be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the same argument
               to the target_link_libraries call.

       

       

         Below is a detailed list of variables that FindQt4.cmake sets.

         QT_MAC_USE_COCOA    For Mac OS X, its whether Cocoa or Carbon is used.
                             In general, this should not be used, but its useful
                             when having platform specific code.

       

         QT_DEFINITIONS   Definitions to use when compiling code that uses Qt.
                          You do not need to use this if you include QT_USE_FILE.
                          The QT_USE_FILE will also define QT_DEBUG and QT_NO_DEBUG
                          to fit your current build type.  Those are not contained
                          in QT_DEFINITIONS.

       

         QT_INCLUDES      List of paths to all include directories of
                          Qt4 QT_INCLUDE_DIR and QT_QTCORE_INCLUDE_DIR are
                          always in this variable even if NOTFOUND,
                          all other INCLUDE_DIRS are
                          only added if they are found.
                          You do not need to use this if you include QT_USE_FILE.

       

       

         Include directories for the Qt modules are listed here.
         You do not need to use these variables if you include QT_USE_FILE.

       The Qt toolkit may contain both debug and release libraries.  In that
       case, the following library variables will contain both.  You do not
       need to use these variables if you include QT_USE_FILE, and use
       QT_LIBRARIES.

         QT_QT3SUPPORT_LIBRARY            The Qt3Support library
         QT_QTASSISTANT_LIBRARY           The QtAssistant library

         QT_QTSCRIPTTOOLS_LIBRARY         The QtScriptTools library

       

       The QtDeclarative library: QT_QTDECLARATIVE_LIBRARY

       also defined, but NOT for general use are

         QT_MOC_EXECUTABLE                   Where to find the moc tool.
         QT_UIC_EXECUTABLE                   Where to find the uic tool.

         QT_LINGUIST_EXECUTABLE              Where to find the Qt linguist tool.

       

       

       These are around for backwards compatibility they will be set

         QT_WRAP_CPP  Set true if QT_MOC_EXECUTABLE is found
         QT_WRAP_UI   Set true if QT_UIC_EXECUTABLE is found

       

       These variables do _NOT_ have any effect anymore (compared to
       FindQt.cmake)

         QT_MT_REQUIRED         Qt4 is now always multithreaded

       

       These variables are set to "" Because Qt structure changed (They make
       no sense in Qt4)

         QT_QT_LIBRARY        Qt-Library is now split


  FindQuickTime
        

       Locate QuickTime This module defines QUICKTIME_LIBRARY
       QUICKTIME_FOUND, if false, do not try to link to gdal
       QUICKTIME_INCLUDE_DIR, where to find the headers

       $QUICKTIME_DIR is an environment variable that would correspond to the
       ./configure --prefix=$QUICKTIME_DIR

       Created by Eric Wing.

  FindRTI
       Try to find M&S HLA RTI libraries

       This module finds if any HLA RTI is installed and locates the standard
       RTI include files and libraries.

       RTI is a simulation infrastructure standardized by IEEE and SISO.  It
       has a well defined C++ API that assures that simulation applications
       are independent on a particular RTI implementation.

         http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation)

       

       This code sets the following variables:

         RTI_INCLUDE_DIR = the directory where RTI includes file are found
         RTI_LIBRARIES = The libraries to link against to use RTI
         RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM
         RTI_FOUND = Set to FALSE if any HLA RTI was not found

       

       Report problems to <certi-devel@nongnu.org>

  FindRuby
       Find Ruby

       This module finds if Ruby is installed and determines where the
       include files and libraries are.  Ruby 1.8 and 1.9 are supported.

       The minimum required version of Ruby can be specified using the
       standard syntax, e.g.  find_package(Ruby 1.8)

       It also determines what the name of the library is.  This code sets
       the following variables:

         RUBY_EXECUTABLE   = full path to the ruby binary
         RUBY_INCLUDE_DIRS = include dirs to be used when using the ruby library
         RUBY_LIBRARY      = full path to the ruby library
         RUBY_VERSION      = the version of ruby which was found, e.g. "1.8.7"
         RUBY_FOUND        = set to true if ruby ws found successfully

       

         RUBY_INCLUDE_PATH = same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it


  FindSDL
       Locate SDL library

       This module defines

         SDL_LIBRARY, the name of the library to link against
         SDL_FOUND, if false, do not try to link to SDL
         SDL_INCLUDE_DIR, where to find SDL.h
         SDL_VERSION_STRING, human-readable string containing the version of SDL

       

       This module responds to the the flag:

         SDL_BUILDING_LIBRARY
           If this is defined, then no SDL_main will be linked in because
           only applications need main().
           Otherwise, it is assumed you are building an application and this
           module will attempt to locate and set the the proper link flags
           as part of the returned SDL_LIBRARY variable.

       

       Don't forget to include SDLmain.h and SDLmain.m your project for the
       OS X framework based version.  (Other versions link to -lSDLmain which
       this module will try to find on your behalf.) Also for OS X, this
       module will automatically add the -framework Cocoa on your behalf.

       

       Additional Note: If you see an empty SDL_LIBRARY_TEMP in your
       configuration and no SDL_LIBRARY, it means CMake did not find your SDL
       library (SDL.dll, libsdl.so, SDL.framework, etc).  Set
       SDL_LIBRARY_TEMP to point to your SDL library, and configure again.
       Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this
       value as appropriate.  These values are used to generate the final
       SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY
       does not get created.

       

       $SDLDIR is an environment variable that would correspond to the
       ./configure --prefix=$SDLDIR used in building SDL.  l.e.galup 9-20-02

       Modified by Eric Wing.  Added code to assist with automated building
       by using environmental variables and providing a more
       controlled/consistent search behavior.  Added new modifications to
       recognize OS X frameworks and additional Unix paths (FreeBSD, etc).
       Also corrected the header search path to follow "proper" SDL
       guidelines.  Added a search for SDLmain which is needed by some
       platforms.  Added a search for threads which is needed by some
       platforms.  Added needed compile switches for MinGW.

       On OSX, this will prefer the Framework version (if found) over others.
       People will have to manually change the cache values of SDL_LIBRARY to
       override this selection or set the CMake environment
       CMAKE_INCLUDE_PATH to modify the search paths.

       Note that the header path has changed from SDL/SDL.h to just SDL.h
       This needed to change because "proper" SDL convention is #include
       "SDL.h", not <SDL/SDL.h>.  This is done for portability reasons
       because not all systems place things in SDL/ (see FreeBSD).

  FindSDL_image
       Locate SDL_image library

       This module defines:

         SDL_IMAGE_LIBRARIES, the name of the library to link against
         SDL_IMAGE_INCLUDE_DIRS, where to find the headers
         SDL_IMAGE_FOUND, if false, do not try to link against
         SDL_IMAGE_VERSION_STRING - human-readable string containing the version of SDL_image

       

       For backward compatiblity the following variables are also set:

         SDLIMAGE_LIBRARY (same value as SDL_IMAGE_LIBRARIES)
         SDLIMAGE_INCLUDE_DIR (same value as SDL_IMAGE_INCLUDE_DIRS)
         SDLIMAGE_FOUND (same value as SDL_IMAGE_FOUND)

       

       $SDLDIR is an environment variable that would correspond to the
       ./configure --prefix=$SDLDIR used in building SDL.

       Created by Eric Wing.  This was influenced by the FindSDL.cmake
       module, but with modifications to recognize OS X frameworks and
       additional Unix paths (FreeBSD, etc).

  FindSDL_mixer
       Locate SDL_mixer library

       This module defines:

         SDL_MIXER_LIBRARIES, the name of the library to link against
         SDL_MIXER_INCLUDE_DIRS, where to find the headers
         SDL_MIXER_FOUND, if false, do not try to link against
         SDL_MIXER_VERSION_STRING - human-readable string containing the version of SDL_mixer

       

       For backward compatiblity the following variables are also set:

         SDLMIXER_LIBRARY (same value as SDL_MIXER_LIBRARIES)
         SDLMIXER_INCLUDE_DIR (same value as SDL_MIXER_INCLUDE_DIRS)
         SDLMIXER_FOUND (same value as SDL_MIXER_FOUND)

       

       $SDLDIR is an environment variable that would correspond to the
       ./configure --prefix=$SDLDIR used in building SDL.

       Created by Eric Wing.  This was influenced by the FindSDL.cmake
       module, but with modifications to recognize OS X frameworks and
       additional Unix paths (FreeBSD, etc).

  FindSDL_net
       Locate SDL_net library

       This module defines:

         SDL_NET_LIBRARIES, the name of the library to link against
         SDL_NET_INCLUDE_DIRS, where to find the headers
         SDL_NET_FOUND, if false, do not try to link against
         SDL_NET_VERSION_STRING - human-readable string containing the version of SDL_net

       

       For backward compatiblity the following variables are also set:

         SDLNET_LIBRARY (same value as SDL_NET_LIBRARIES)
         SDLNET_INCLUDE_DIR (same value as SDL_NET_INCLUDE_DIRS)
         SDLNET_FOUND (same value as SDL_NET_FOUND)

       

       $SDLDIR is an environment variable that would correspond to the

       module, but with modifications to recognize OS X frameworks and
       additional Unix paths (FreeBSD, etc).

  FindSDL_sound
       Locates the SDL_sound library

       

       This module depends on SDL being found and must be called AFTER
       FindSDL.cmake is called.

       This module defines

         SDL_SOUND_INCLUDE_DIR, where to find SDL_sound.h
         SDL_SOUND_FOUND, if false, do not try to link to SDL_sound
         SDL_SOUND_LIBRARIES, this contains the list of libraries that you need
           to link against. This is a read-only variable and is marked INTERNAL.
         SDL_SOUND_EXTRAS, this is an optional variable for you to add your own
           flags to SDL_SOUND_LIBRARIES. This is prepended to SDL_SOUND_LIBRARIES.
           This is available mostly for cases this module failed to anticipate for
           and you must add additional flags. This is marked as ADVANCED.
         SDL_SOUND_VERSION_STRING, human-readable string containing the version of SDL_sound

       

       This module also defines (but you shouldn't need to use directly)

          SDL_SOUND_LIBRARY, the name of just the SDL_sound library you would link
          against. Use SDL_SOUND_LIBRARIES for you link instructions and not this one.

       And might define the following as needed

          MIKMOD_LIBRARY
          MODPLUG_LIBRARY
          OGG_LIBRARY
          VORBIS_LIBRARY
          SMPEG_LIBRARY
          FLAC_LIBRARY
          SPEEX_LIBRARY

       

       Typically, you should not use these variables directly, and you should
       use SDL_SOUND_LIBRARIES which contains SDL_SOUND_LIBRARY and the other
       audio libraries (if needed) to successfully compile on your system.

       Created by Eric Wing.  This module is a bit more complicated than the
       other FindSDL* family modules.  The reason is that SDL_sound can be
       compiled in a large variety of different ways which are independent of
       platform.  SDL_sound may dynamically link against other 3rd party
       libraries to get additional codec support, such as Ogg Vorbis, SMPEG,
       ModPlug, MikMod, FLAC, Speex, and potentially others.  Under some
       circumstances which I don't fully understand, there seems to be a
       requirement that dependent libraries of libraries you use must also be
       explicitly linked against in order to successfully compile.  SDL_sound
       does not currently have any system in place to know how it was
       compiled.  So this CMake module does the hard work in trying to
       discover which 3rd party libraries are required for building (if any).
       This module uses a brute force approach to create a test program that
       uses SDL_sound, and then tries to build it.  If the build fails, it
       parses the error output for known symbol names to figure out which
       libraries are needed.

       Responds to the $SDLDIR and $SDLSOUNDDIR environmental variable that
       would correspond to the ./configure --prefix=$SDLDIR used in building
       SDL.

       On OSX, this will prefer the Framework version (if found) over others.
       People will have to manually change the cache values of SDL_LIBRARY to
       override this selectionor set the CMake environment CMAKE_INCLUDE_PATH
       to modify the search paths.

  FindSDL_ttf
       Locate SDL_ttf library

       This module defines:

         SDL_TTF_LIBRARIES, the name of the library to link against
         SDL_TTF_INCLUDE_DIRS, where to find the headers
         SDL_TTF_FOUND, if false, do not try to link against
         SDL_TTF_VERSION_STRING - human-readable string containing the version of SDL_ttf

       

       For backward compatiblity the following variables are also set:

         SDLTTF_LIBRARY (same value as SDL_TTF_LIBRARIES)
         SDLTTF_INCLUDE_DIR (same value as SDL_TTF_INCLUDE_DIRS)
         SDLTTF_FOUND (same value as SDL_TTF_FOUND)

       

       $SDLDIR is an environment variable that would correspond to the
       ./configure --prefix=$SDLDIR used in building SDL.

       Created by Eric Wing.  This was influenced by the FindSDL.cmake
       module, but with modifications to recognize OS X frameworks and
       additional Unix paths (FreeBSD, etc).

  FindSWIG
       Find SWIG

       This module finds an installed SWIG.  It sets the following variables:

         SWIG_FOUND - set to true if SWIG is found
         SWIG_DIR - the directory where swig is installed
         SWIG_EXECUTABLE - the path to the swig executable
         SWIG_VERSION   - the version number of the swig executable

       

       The minimum required version of SWIG can be specified using the
       standard syntax, e.g.  find_package(SWIG 1.1)

       All information is collected from the SWIG_EXECUTABLE so the version
       to be found can be changed from the command line by means of setting
       SWIG_EXECUTABLE


  FindSelfPackers
       Find upx

       This module looks for some executable packers (i.e.  software that
       compress executables or shared libs into on-the-fly self-extracting
       executables or shared libs.  Examples:

         UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html


  FindSquish
       -- Typical Use

       

       This module can be used to find Squish.  Currently Squish versions 3
       and 4 are supported.

         SQUISH_FOUND                    If false, don't try to use Squish
         SQUISH_VERSION                  The full version of Squish found
         SQUISH_VERSION_MAJOR            The major version of Squish found
         SQUISH_VERSION_MINOR            The minor version of Squish found
         SQUISH_VERSION_PATCH            The patch version of Squish found

       

         SQUISH_INSTALL_DIR              The Squish installation directory (containing bin, lib, etc)
         SQUISH_SERVER_EXECUTABLE        The squishserver executable
         SQUISH_CLIENT_EXECUTABLE        The squishrunner executable

       

         SQUISH_INSTALL_DIR_FOUND        Was the install directory found?
         SQUISH_SERVER_EXECUTABLE_FOUND  Was the server executable found?
         SQUISH_CLIENT_EXECUTABLE_FOUND  Was the client executable found?

       

       It provides the function squish_v4_add_test() for adding a squish test
       to cmake using Squish 4.x:

          squish_v4_add_test(cmakeTestName AUT targetName SUITE suiteName TEST squishTestName
                          [SETTINGSGROUP group] [PRE_COMMAND command] [POST_COMMAND command] )

       

       The arguments have the following meaning:

          cmakeTestName: this will be used as the first argument for add_test()
          AUT targetName: the name of the cmake target which will be used as AUT, i.e. the
                          executable which will be tested.
          SUITE suiteName: this is either the full path to the squish suite, or just the
                           last directory of the suite, i.e. the suite name. In this case
                           the CMakeLists.txt which calls squish_add_test() must be located
                           in the parent directory of the suite directory.
          TEST squishTestName: the name of the squish test, i.e. the name of the subdirectory
                               of the test inside the suite directory.
          SETTINGSGROUP group: if specified, the given settings group will be used for executing the test.
                               If not specified, the groupname will be "CTest_<username>"
          PRE_COMMAND command:  if specified, the given command will be executed before starting the squish test.
          POST_COMMAND command: same as PRE_COMMAND, but after the squish test has been executed.

       

          enable_testing()
          find_package(Squish 4.0)
          if (SQUISH_FOUND)
             squish_v4_add_test(myTestName AUT myApp SUITE ${CMAKE_SOURCE_DIR}/tests/mySuite TEST someSquishTest SETTINGSGROUP myGroup )
          endif ()

       

       

       For users of Squish version 3.x the macro squish_v3_add_test() is
       provided:

          squish_v3_add_test(testName applicationUnderTest testCase envVars testWrapper)
          Use this macro to add a test using Squish 3.x.

       

         enable_testing()
         find_package(Squish)
         if (SQUISH_FOUND)
           squish_v3_add_test(myTestName myApplication testCase envVars testWrapper)
         endif ()

       

       macro SQUISH_ADD_TEST(testName applicationUnderTest testCase envVars
       testWrapper)

          This is deprecated. Use SQUISH_V3_ADD_TEST() if you are using Squish 3.x instead.


  FindSubversion
       Extract information from a subversion working copy

       The module defines the following variables:

         Subversion_SVN_EXECUTABLE - path to svn command line client
         Subversion_VERSION_SVN - version of svn command line client
         Subversion_FOUND - true if the command line client was found
         SUBVERSION_FOUND - same as Subversion_FOUND, set for compatiblity reasons

       

       The minimum required version of Subversion can be specified using the
       standard syntax, e.g.  find_package(Subversion 1.4)

       If the command line client executable is found two macros are defined:

         Subversion_WC_INFO(<dir> <var-prefix>)
         Subversion_WC_LOG(<dir> <var-prefix>)

       Subversion_WC_INFO extracts information of a subversion working copy
       at a given location.  This macro defines the following variables:

         <var-prefix>_WC_URL - url of the repository (at <dir>)
         <var-prefix>_WC_ROOT - root url of the repository
         <var-prefix>_WC_REVISION - current revision
         <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
         <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
         <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
         <var-prefix>_WC_INFO - output of command `svn info <dir>'

       Subversion_WC_LOG retrieves the log message of the base revision of a
       subversion working copy at a given location.  This macro defines the
       variable:

         <var-prefix>_LAST_CHANGED_LOG - last log of base revision

       Example usage:

         find_package(Subversion)
         if(SUBVERSION_FOUND)
           Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
           message("Current revision is ${Project_WC_REVISION}")
           Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
           message("Last changed log is ${Project_LAST_CHANGED_LOG}")
         endif()


  FindTCL
       TK_INTERNAL_PATH was removed.

       This module finds if Tcl is installed and determines where the include
       files and libraries are.  It also determines what the name of the
       library is.  This code sets the following variables:

         TCL_FOUND              = Tcl was found
         TK_FOUND               = Tk was found
         TCLTK_FOUND            = Tcl and Tk were found
         TCL_LIBRARY            = path to Tcl library (tcl tcl80)
         TCL_INCLUDE_PATH       = path to where tcl.h can be found
         TCL_TCLSH              = path to tclsh binary (tcl tcl80)
         TK_LIBRARY             = path to Tk library (tk tk80 etc)
         TK_INCLUDE_PATH        = path to where tk.h can be found
         TK_WISH                = full path to the wish executable

       

       In an effort to remove some clutter and clear up some issues for
       people who are not necessarily Tcl/Tk gurus/developpers, some
       variables were moved or removed.  Changes compared to CMake 2.4 are:

          => they were only useful for people writing Tcl/Tk extensions.
          => these libs are not packaged by default with Tcl/Tk distributions.
             Even when Tcl/Tk is built from source, several flavors of debug libs
             are created and there is no real reason to pick a single one
             specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
             Let's leave that choice to the user by allowing him to assign
             TCL_LIBRARY to any Tcl library, debug or not.
          => this ended up being only a Win32 variable, and there is a lot of
             confusion regarding the location of this file in an installed Tcl/Tk
             tree anyway (see 8.5 for example). If you need the internal path at
             this point it is safer you ask directly where the *source* tree is
             and dig from there.


  FindTIFF
       Find TIFF library

       Find the native TIFF includes and library This module defines

         TIFF_INCLUDE_DIR, where to find tiff.h, etc.
         TIFF_LIBRARIES, libraries to link against to use TIFF.
         TIFF_FOUND, If false, do not try to use TIFF.

       also defined, but not for general use are

         TIFF_LIBRARY, where to find the TIFF library.


  FindTclStub
       TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed.

       This module finds Tcl stub libraries.  It first finds Tcl include
       files and libraries by calling FindTCL.cmake.  How to Use the Tcl
       Stubs Library:

          http://tcl.activestate.com/doc/howto/stubs.html

       Using Stub Libraries:

          http://safari.oreilly.com/0130385603/ch48lev1sec3

       This code sets the following variables:

         TCL_STUB_LIBRARY       = path to Tcl stub library
         TK_STUB_LIBRARY        = path to Tk stub library
         TTK_STUB_LIBRARY       = path to ttk stub library

       

       In an effort to remove some clutter and clear up some issues for
       people who are not necessarily Tcl/Tk gurus/developpers, some
       variables were moved or removed.  Changes compared to CMake 2.4 are:

             TCL_STUB_LIBRARY to any Tcl library, debug or not.


  FindTclsh
       Find tclsh

       This module finds if TCL is installed and determines where the include
       files and libraries are.  It also determines what the name of the
       library is.  This code sets the following variables:

         TCLSH_FOUND = TRUE if tclsh has been found
         TCL_TCLSH = the path to the tclsh executable

       In cygwin, look for the cygwin version first.  Don't look for it later
       to avoid finding the cygwin version on a Win32 build.

  FindThreads
       This module determines the thread library of the system.

       The following variables are set

         CMAKE_THREAD_LIBS_INIT     - the thread library
         CMAKE_USE_SPROC_INIT       - are we using sproc?
         CMAKE_USE_WIN32_THREADS_INIT - using WIN32 threads?
         CMAKE_USE_PTHREADS_INIT    - are we using pthreads
         CMAKE_HP_PTHREADS_INIT     - are we using hp pthreads

       For systems with multiple thread libraries, caller can set

         CMAKE_THREAD_PREFER_PTHREAD


  FindUnixCommands
       Find unix commands from cygwin

       This module looks for some usual Unix commands.


  FindVTK
       Find a VTK installation or build tree.

       The following variables are set if VTK is found.  If VTK is not found,
       VTK_FOUND is set to false.

         VTK_FOUND         - Set to true when VTK is found.
         VTK_USE_FILE      - CMake file to use VTK.
         VTK_MAJOR_VERSION - The VTK major version number.
         VTK_MINOR_VERSION - The VTK minor version number
                              (odd non-release).
         VTK_BUILD_VERSION - The VTK patch level
                              (meaningless for odd minor).
         VTK_INCLUDE_DIRS  - Include directories for VTK
         VTK_LIBRARY_DIRS  - Link directories for VTK libraries
         VTK_KITS          - List of VTK kits, in CAPS
                             (COMMON,IO,) etc.
         VTK_LANGUAGES     - List of wrapped languages, in CAPS
                             (TCL, PYHTON,) etc.

       The following cache entries must be set by the user to locate VTK:

         VTK_DIR  - The directory containing VTKConfig.cmake.
                    This is either the root of the build tree,
                    or the lib/vtk directory.  This is the
                    only cache entry.

       The following variables are set for backward compatibility and should
       not be used in new code:

         USE_VTK_FILE - The full path to the UseVTK.cmake file.
                        This is provided for backward
                        compatibility.  Use VTK_USE_FILE

  Findosg
        

       

       NOTE: It is highly recommended that you use the new
       FindOpenSceneGraph.cmake introduced in CMake 2.6.3 and not use this
       Find module directly.

       This is part of the Findosg* suite used to find OpenSceneGraph
       components.  Each component is separate and you must opt in to each
       module.  You must also opt into OpenGL and OpenThreads (and Producer
       if needed) as these modules won't do it for you.  This is to allow you
       control over your own system piece by piece in case you need to opt
       out of certain components or change the Find behavior for a particular
       module (perhaps because the default FindOpenGL.cmake module doesn't
       work with your system as an example).  If you want to use a more
       convenient module that includes everything, use the
       FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

       Locate osg This module defines

       OSG_FOUND - Was the Osg found? OSG_INCLUDE_DIR - Where to find the

       this)

       OSG_LIBRARY - The OSG library OSG_LIBRARY_DEBUG - The OSG debug
       library

       $OSGDIR is an environment variable that would correspond to the
       ./configure --prefix=$OSGDIR used in building osg.

  FindosgShadow
        

       This is part of the Findosg* suite used to find OpenSceneGraph
       components.  Each component is separate and you must opt in to each
       module.  You must also opt into OpenGL and OpenThreads (and Producer
       if needed) as these modules won't do it for you.  This is to allow you
       control over your own system piece by piece in case you need to opt
       out of certain components or change the Find behavior for a particular
       module (perhaps because the default FindOpenGL.cmake module doesn't
       work with your system as an example).  If you want to use a more
       convenient module that includes everything, use the
       FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

  FindwxWidgets
       Find a wxWidgets (a.k.a., wxWindows) installation.

       This module finds if wxWidgets is installed and selects a default
       configuration to use.  wxWidgets is a modular library.  To specify the
       modules that you will use, you need to name them as components to the
       package:

       find_package(wxWidgets COMPONENTS core base ...)

       There are two search branches: a windows style and a unix style.  For
       windows, the following variables are searched for and set to defaults
       in case of multiple choices.  Change them if the defaults are not
       desired (i.e., these are the only variables you should change to
       select a configuration):

         wxWidgets_ROOT_DIR      - Base wxWidgets directory
                                   (e.g., C:/wxWidgets-2.6.3).
         wxWidgets_LIB_DIR       - Path to wxWidgets libraries
                                   (e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
         wxWidgets_CONFIGURATION - Configuration to use
                                   (e.g., msw, mswd, mswu, mswunivud, etc.)
         wxWidgets_EXCLUDE_COMMON_LIBRARIES
                                 - Set to TRUE to exclude linking of
                                   commonly required libs (e.g., png tiff
                                   jpeg zlib regex expat).

       

       For unix style it uses the wx-config utility.  You can select between
       debug/release, unicode/ansi, universal/non-universal, and
       static/shared in the QtDialog or ccmake interfaces by turning ON/OFF
       the following variables:

         wxWidgets_USE_DEBUG
         wxWidgets_USE_UNICODE
         wxWidgets_USE_UNIVERSAL
         wxWidgets_USE_STATIC

       

       There is also a wxWidgets_CONFIG_OPTIONS variable for all other
       options that need to be passed to the wx-config utility.  For example,
       to use the base toolkit found in the /usr/local path, set the variable
       (before calling the FIND_PACKAGE command) as such:

         set(wxWidgets_CONFIG_OPTIONS --toolkit=base --prefix=/usr)

       

       The following are set after the configuration is done for both windows
       and unix style:

         wxWidgets_FOUND            - Set to TRUE if wxWidgets was found.
         wxWidgets_INCLUDE_DIRS     - Include directories for WIN32
                                      i.e., where to find "wx/wx.h" and
                                      "wx/setup.h"; possibly empty for unices.
         wxWidgets_LIBRARIES        - Path to the wxWidgets libraries.
         wxWidgets_LIBRARY_DIRS     - compile time link dirs, useful for
                                      rpath on UNIX. Typically an empty string
                                      in WIN32 environment.
         wxWidgets_DEFINITIONS      - Contains defines required to compile/link
                                      against WX, e.g. WXUSINGDLL
         wxWidgets_DEFINITIONS_DEBUG- Contains defines required to compile/link
                                      against WX debug builds, e.g. __WXDEBUG__
         wxWidgets_CXX_FLAGS        - Include dirs and compiler flags for
                                      unices, empty on WIN32. Essentially
                                      "`wx-config --cxxflags`".
         wxWidgets_USE_FILE         - Convenience include file.

       

       Sample usage:

          # Note that for MinGW users the order of libs is important!
          find_package(wxWidgets COMPONENTS net gl core base)
          if(wxWidgets_FOUND)
            include(${wxWidgets_USE_FILE})
            # and for each of your dependent executable/library targets:
            target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})
          endif()

       

       If wxWidgets is required (i.e., not an optional part):

          find_package(wxWidgets REQUIRED net gl core base)
          include(${wxWidgets_USE_FILE})
          # and for each of your dependent executable/library targets:
          target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})


  FindwxWindows
       Find wxWindows (wxWidgets) installation

       This module finds if wxWindows/wxWidgets is installed and determines
       where the include files and libraries are.  It also determines what
       the name of the library is.  Please note this file is DEPRECATED and
       replaced by FindwxWidgets.cmake.  This code sets the following
       variables:

         WXWINDOWS_FOUND     = system has WxWindows

  FortranCInterface
       Fortran/C Interface Detection

       This module automatically detects the API by which C and Fortran
       languages interact.  Variables indicate if the mangling is found:

          FortranCInterface_GLOBAL_FOUND = Global subroutines and functions
          FortranCInterface_MODULE_FOUND = Module subroutines and functions
                                           (declared by "MODULE PROCEDURE")

       A function is provided to generate a C header file containing macros
       to mangle symbol names:

          FortranCInterface_HEADER(<file>
                                   [MACRO_NAMESPACE <macro-ns>]
                                   [SYMBOL_NAMESPACE <ns>]
                                   [SYMBOLS [<module>:]<function> ...])

       It generates in <file> definitions of the following macros:

          #define FortranCInterface_GLOBAL (name,NAME) ...
          #define FortranCInterface_GLOBAL_(name,NAME) ...
          #define FortranCInterface_MODULE (mod,name, MOD,NAME) ...
          #define FortranCInterface_MODULE_(mod,name, MOD,NAME) ...

       These macros mangle four categories of Fortran symbols, respectively:

          - Global symbols without '_': call mysub()
          - Global symbols with '_'   : call my_sub()
          - Module symbols without '_': use mymod; call mysub()
          - Module symbols with '_'   : use mymod; call my_sub()

       If mangling for a category is not known, its macro is left undefined.
       All macros require raw names in both lower case and upper case.  The
       MACRO_NAMESPACE option replaces the default "FortranCInterface_"
       prefix with a given namespace "<macro-ns>".

       The SYMBOLS option lists symbols to mangle automatically with C
       preprocessor definitions:

          <function>          ==> #define <ns><function> ...
          <module>:<function> ==> #define <ns><module>_<function> ...

       If the mangling for some symbol is not known then no preprocessor
       definition is created, and a warning is displayed.  The
       SYMBOL_NAMESPACE option prefixes all preprocessor definitions
       generated by the SYMBOLS option with a given namespace "<ns>".

       Example usage:

          include(FortranCInterface)
          FortranCInterface_HEADER(FC.h MACRO_NAMESPACE "FC_")

       This creates a "FC.h" header that defines mangling macros FC_GLOBAL(),
       FC_GLOBAL_(), FC_MODULE(), and FC_MODULE_().

       Example usage:

          include(FortranCInterface)
          FortranCInterface_HEADER(FCMangle.h
                                   MACRO_NAMESPACE "FC_"
                                   SYMBOL_NAMESPACE "FC_"
                                   SYMBOLS mysub mymod:my_sub)

       This creates a "FCMangle.h" header that defines the same FC_*()
       mangling macros as the previous example plus preprocessor symbols
       FC_mysub and FC_mymod_my_sub.

       Another function is provided to verify that the Fortran and C/C++
       compilers work together:

          FortranCInterface_VERIFY([CXX] [QUIET])

       It tests whether a simple test executable using Fortran and C (and C++
       when the CXX option is given) compiles and links successfully.  The
       result is stored in the cache entry FortranCInterface_VERIFIED_C (or
       FortranCInterface_VERIFIED_CXX if CXX is given) as a boolean.  If the
       check fails and QUIET is not given the function terminates with a
       FATAL_ERROR message describing the problem.  The purpose of this check
       is to stop a build early for incompatible compiler combinations.  The
       test is built in the Release configuration.

       FortranCInterface is aware of possible GLOBAL and MODULE manglings for
       many Fortran compilers, but it also provides an interface to specify
       new possible manglings.  Set the variables

          FortranCInterface_GLOBAL_SYMBOLS
          FortranCInterface_MODULE_SYMBOLS

       before including FortranCInterface to specify manglings of the symbols
       "MySub", "My_Sub", "MyModule:MySub", and "My_Module:My_Sub".  For
       example, the code:

          include(FortranCInterface)

       tells FortranCInterface to try given GLOBAL and MODULE manglings.
       (The carets point at raw symbol names for clarity in this example but
       are not needed.)

  GNUInstallDirs
       Define GNU standard installation directories

       Provides install directory variables as defined for GNU software:

         http://www.gnu.org/prep/standards/html_node/Directory-Variables.html

       Inclusion of this module defines the following variables:

         CMAKE_INSTALL_<dir>      - destination for files of a given type
         CMAKE_INSTALL_FULL_<dir> - corresponding absolute path

       where <dir> is one of:

         BINDIR           - user executables (bin)
         SBINDIR          - system admin executables (sbin)
         LIBEXECDIR       - program executables (libexec)
         SYSCONFDIR       - read-only single-machine data (etc)
         SHAREDSTATEDIR   - modifiable architecture-independent data (com)
         LOCALSTATEDIR    - modifiable single-machine data (var)
         LIBDIR           - object code libraries (lib or lib64 or lib/<multiarch-tuple> on Debian)
         INCLUDEDIR       - C header files (include)
         OLDINCLUDEDIR    - C header files for non-gcc (/usr/include)
         DATAROOTDIR      - read-only architecture-independent data root (share)
         DATADIR          - read-only architecture-independent data (DATAROOTDIR)
         INFODIR          - info documentation (DATAROOTDIR/info)
         LOCALEDIR        - locale-dependent data (DATAROOTDIR/locale)
         MANDIR           - man documentation (DATAROOTDIR/man)
         DOCDIR           - documentation root (DATAROOTDIR/doc/PROJECT_NAME)

       Each CMAKE_INSTALL_<dir> value may be passed to the DESTINATION
       options of install() commands for the corresponding file type.  If the
       includer does not define a value the above-shown default will be used
       and the value will appear in the cache for editing by the user.  Each
       CMAKE_INSTALL_FULL_<dir> value contains an absolute path constructed
       from the corresponding destination by prepending (if necessary) the
       value of CMAKE_INSTALL_PREFIX.

  GenerateExportHeader
       Function for generation of export macros for libraries

       This module provides the function GENERATE_EXPORT_HEADER() and the
       accompanying ADD_COMPILER_EXPORT_FLAGS() function.

       The GENERATE_EXPORT_HEADER function can be used to generate a file
       suitable for preprocessor inclusion which contains EXPORT macros to be
       used in library classes.

       GENERATE_EXPORT_HEADER( LIBRARY_TARGET

                    [BASE_NAME <base_name>]
                    [EXPORT_MACRO_NAME <export_macro_name>]
                    [EXPORT_FILE_NAME <export_file_name>]
                    [DEPRECATED_MACRO_NAME <deprecated_macro_name>]
                    [NO_EXPORT_MACRO_NAME <no_export_macro_name>]
                    [STATIC_DEFINE <static_define>]
                    [NO_DEPRECATED_MACRO_NAME <no_deprecated_macro_name>]
                    [DEFINE_NO_DEPRECATED]
                    [PREFIX_NAME <prefix_name>]

       )

       ADD_COMPILER_EXPORT_FLAGS( [<output_variable>] )

       By default GENERATE_EXPORT_HEADER() generates macro names in a file
       name determined by the name of the library.  The
       ADD_COMPILER_EXPORT_FLAGS function adds -fvisibility=hidden to
       CMAKE_CXX_FLAGS if supported, and is a no-op on Windows which does not
       need extra compiler flags for exporting support.  You may optionally
       pass a single argument to ADD_COMPILER_EXPORT_FLAGS that will be
       populated with the required CXX_FLAGS required to enable visibility
       support for the compiler/architecture in use.

       This means that in the simplest case, users of these functions will be
       equivalent to:

          add_compiler_export_flags()
          add_library(somelib someclass.cpp)
          generate_export_header(somelib)
          install(TARGETS somelib DESTINATION ${LIBRARY_INSTALL_DIR})
          install(FILES
           someclass.h
           ${PROJECT_BINARY_DIR}/somelib_export.h DESTINATION ${INCLUDE_INSTALL_DIR}
          )

       

       And in the ABI header files:

          #include "somelib_export.h"
          class SOMELIB_EXPORT SomeClass {
            ...
          };

       

       The CMake fragment will generate a file in the
       ${CMAKE_CURRENT_BINARY_DIR} called somelib_export.h containing the
       macros SOMELIB_EXPORT, SOMELIB_NO_EXPORT, SOMELIB_DEPRECATED,
       SOMELIB_DEPRECATED_EXPORT and SOMELIB_DEPRECATED_NO_EXPORT.  The
       resulting file should be installed with other headers in the library.

       The BASE_NAME argument can be used to override the file name and the
       names used for the macros

          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            BASE_NAME other_name
          )

       

       Generates a file called other_name_export.h containing the macros
       OTHER_NAME_EXPORT, OTHER_NAME_NO_EXPORT and OTHER_NAME_DEPRECATED etc.

       The BASE_NAME may be overridden by specifiying other options in the
       function.  For example:

          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            EXPORT_MACRO_NAME OTHER_NAME_EXPORT
          )

       

       creates the macro OTHER_NAME_EXPORT instead of SOMELIB_EXPORT, but
       other macros and the generated file name is as default.

          add_library(somelib someclass.cpp)
          generate_export_header(somelib
            DEPRECATED_MACRO_NAME KDE_DEPRECATED
          )

       

       creates the macro KDE_DEPRECATED instead of SOMELIB_DEPRECATED.

       If LIBRARY_TARGET is a static library, macros are defined without
       values.

       If the same sources are used to create both a shared and a static
       library, the uppercased symbol ${BASE_NAME}_STATIC_DEFINE should be
       used when building the static library

          add_library(shared_variant SHARED ${lib_SRCS})
          add_library(static_variant ${lib_SRCS})
          generate_export_header(shared_variant BASE_NAME libshared_and_static)
          set_target_properties(static_variant PROPERTIES
            COMPILE_FLAGS -DLIBSHARED_AND_STATIC_STATIC_DEFINE)

       

       This will cause the export macros to expand to nothing when building
       the static library.

       If DEFINE_NO_DEPRECATED is specified, then a macro
       ${BASE_NAME}_NO_DEPRECATED will be defined This macro can be used to
       remove deprecated code from preprocessor output.

          option(EXCLUDE_DEPRECATED "Exclude deprecated parts of the library" FALSE)
          if (EXCLUDE_DEPRECATED)
            set(NO_BUILD_DEPRECATED DEFINE_NO_DEPRECATED)
          endif()
          generate_export_header(somelib ${NO_BUILD_DEPRECATED})

       

       And then in somelib:

          class SOMELIB_EXPORT SomeClass
          {
          public:
          #ifndef SOMELIB_NO_DEPRECATED
            SOMELIB_DEPRECATED void oldMethod();
          #endif
          };

       

          #ifndef SOMELIB_NO_DEPRECATED
          void SomeClass::oldMethod() {  }
          #endif

       

       If PREFIX_NAME is specified, the argument will be used as a prefix to
       all generated macros.

       For example:

          generate_export_header(somelib PREFIX_NAME VTK_)

       

       Generates the macros VTK_SOMELIB_EXPORT etc.

  GetPrerequisites
       Functions to analyze and list executable file prerequisites.

       This module provides functions to list the .dll, .dylib or .so files
       that an executable or shared library file depends on.  (Its
       prerequisites.)

       It uses various tools to obtain the list of required shared library
       files:

          dumpbin (Windows)
          objdump (MinGW on Windows)
          ldd (Linux/Unix)
          otool (Mac OSX)

       The following functions are provided by this module:

          get_prerequisites
          list_prerequisites
          list_prerequisites_by_glob
          gp_append_unique
          is_file_executable
          gp_item_default_embedded_path
            (projects can override with gp_item_default_embedded_path_override)
          gp_resolve_item
            (projects can override with gp_resolve_item_override)
          gp_resolved_file_type
            (projects can override with gp_resolved_file_type_override)
          gp_file_type

       Requires CMake 2.6 or greater because it uses function, break, return
       and PARENT_SCOPE.

         GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse>
                           <exepath> <dirs>)

       Get the list of shared library files required by <target>.  The list
       in the variable named <prerequisites_var> should be empty on first
       entry to this function.  On exit, <prerequisites_var> will contain the
       list of required shared library files.

       <target> is the full path to an executable file.  <prerequisites_var>
       is the name of a CMake variable to contain the results.
       <exclude_system> must be 0 or 1 indicating whether to include or
       exclude "system" prerequisites.  If <recurse> is set to 1 all
       prerequisites will be found recursively, if set to 0 only direct
       prerequisites are listed.  <exepath> is the path to the top level
       executable used for @executable_path replacment on the Mac.  <dirs> is
       a list of paths where libraries might be found: these paths are
       searched first when a target without any path info is given.  Then
       standard system locations are also searched: PATH, Framework
       locations, /usr/lib...

         LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]])

       Print a message listing the prerequisites of <target>.

       <target> is the name of a shared library or executable target or the
       full path to a shared library or executable file.  If <recurse> is set
       to 1 all prerequisites will be found recursively, if set to 0 only
       direct prerequisites are listed.  <exclude_system> must be 0 or 1
       indicating whether to include or exclude "system" prerequisites.  With
       <verbose> set to 0 only the full path names of the prerequisites are
       printed, set to 1 extra informatin will be displayed.

         LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>)

       Print the prerequisites of shared library and executable files
       matching a globbing pattern.  <glob_arg> is GLOB or GLOB_RECURSE and
       <glob_exp> is a globbing expression used with "file(GLOB" or
       "file(GLOB_RECURSE" to retrieve a list of matching files.  If a
       matching file is executable, its prerequisites are listed.

       Any additional (optional) arguments provided are passed along as the
       optional arguments to the list_prerequisites calls.

         GP_APPEND_UNIQUE(<list_var> <value>)

       Append <value> to the list variable <list_var> only if the value is
       not already in the list.

         IS_FILE_EXECUTABLE(<file> <result_var>)

       Return 1 in <result_var> if <file> is a binary executable, 0
       otherwise.

         GP_ITEM_DEFAULT_EMBEDDED_PATH(<item> <default_embedded_path_var>)

       Return the path that others should refer to the item by when the item
       is embedded inside a bundle.

       Override on a per-project basis by providing a project-specific
       gp_item_default_embedded_path_override function.

         GP_RESOLVE_ITEM(<context> <item> <exepath> <dirs> <resolved_item_var>)

       Resolve an item into an existing full path file.

       Override on a per-project basis by providing a project-specific
       gp_resolve_item_override function.

         GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var>)

       Return the type of <file> with respect to <original_file>.  String
       describing type of prerequisite is returned in variable named
       <type_var>.

       Use <exepath> and <dirs> if necessary to resolve non-absolute <file>
       values -- but only for non-embedded items.

       Possible types are:

          system
          local
          embedded
          other

       Override on a per-project basis by providing a project-specific
       gp_resolved_file_type_override function.

         GP_FILE_TYPE(<original_file> <file> <type_var>)

       Return the type of <file> with respect to <original_file>.  String
       describing type of prerequisite is returned in variable named
       <type_var>.

       Possible types are:

          system
          local
          embedded
          other


  InstallRequiredSystemLibraries
        

       By including this file, all library files listed in the variable
       CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS will be installed with
       install(PROGRAMS ...) into bin for WIN32 and lib for non-WIN32.  If
       CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP is set to TRUE before including
       this file, then the INSTALL command is not called.  The user can use
       the variable CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS to use a custom install
       command and install them however they want.  If it is the MSVC
       compiler, then the microsoft run time libraries will be found and
       automatically added to the CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS, and
       installed.  If CMAKE_INSTALL_DEBUG_LIBRARIES is set and it is the MSVC
       compiler, then the debug libraries are installed when available.  If
       CMAKE_INSTALL_DEBUG_LIBRARIES_ONLY is set then only the debug
       libraries are installed when both debug and release are available.  If
       CMAKE_INSTALL_MFC_LIBRARIES is set then the MFC run time libraries are
       installed as well as the CRT run time libraries.  If
       CMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION is set then the libraries are
       installed to that directory rather than the default.  If
       CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS is NOT set, then this
       file warns about required files that do not exist.  You can set this
       variable to ON before including this file to avoid the warning.  For
       example, the Visual Studio Express editions do not include the
       redistributable files, so if you include this file on a machine with
       only VS Express installed, you'll get the warning.

  MacroAddFileDependencies
       MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...)

       Using the macro MACRO_ADD_FILE_DEPENDENCIES() is discouraged.  There
       are usually better ways to specify the correct dependencies.

       MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...) is just a
       convenience wrapper around the OBJECT_DEPENDS source file property.
       You can just use set_property(SOURCE <file> APPEND PROPERTY
       OBJECT_DEPENDS depend_files) instead.

  ProcessorCount
       ProcessorCount(var)

       Determine the number of processors/cores and save value in ${var}

       Sets the variable named ${var} to the number of physical cores
       available on the machine if the information can be determined.
       Otherwise it is set to 0.  Currently this functionality is implemented
       for AIX, cygwin, FreeBSD, HPUX, IRIX, Linux, Mac OS X, QNX, Sun and
       Windows.

       This function is guaranteed to return a positive integer (>=1) if it
       succeeds.  It returns 0 if there's a problem determining the processor
       count.

       Example use, in a ctest -S dashboard script:

          include(ProcessorCount)
          ProcessorCount(N)
          if(NOT N EQUAL 0)
            set(CTEST_BUILD_FLAGS -j${N})
            set(ctest_test_args ${ctest_test_args} PARALLEL_LEVEL ${N})
          endif()

       

       This function is intended to offer an approximation of the value of
       the number of compute cores available on the current machine, such
       that you may use that value for parallel building and parallel
       testing.  It is meant to help utilize as much of the machine as seems
       reasonable.  Of course, knowledge of what else might be running on the
       machine simultaneously should be used when deciding whether to request
       a machine's full capacity all for yourself.

  SelectLibraryConfigurations
        

       select_library_configurations( basename )

       This macro takes a library base name as an argument, and will choose
       good values for basename_LIBRARY, basename_LIBRARIES,
       basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE depending on what
       has been found and set.  If only basename_LIBRARY_RELEASE is defined,
       basename_LIBRARY will be set to the release value, and
       basename_LIBRARY_DEBUG will be set to basename_LIBRARY_DEBUG-NOTFOUND.
       If only basename_LIBRARY_DEBUG is defined, then basename_LIBRARY will
       take the debug value, and basename_LIBRARY_RELEASE will be set to
       basename_LIBRARY_RELEASE-NOTFOUND.

       If the generator supports configuration types, then basename_LIBRARY
       and basename_LIBRARIES will be set with debug and optimized flags
       specifying the library to be used for the given configuration.  If no
       build type has been set or the generator in use does not support
       configuration types, then basename_LIBRARY and basename_LIBRARIES will
       take only the release value, or the debug value if the release one is
       not set.

  SquishTestScript
        

       

       This script launches a GUI test using Squish.  You should not call the
       script directly; instead, you should access it via the SQUISH_ADD_TEST
       macro that is defined in FindSquish.cmake.

       This script starts the Squish server, launches the test on the client,
       and finally stops the squish server.  If any of these steps fail
       (including if the tests do not pass) then a fatal error is raised.

                [ENTRY_POINT entry]
                [VERSION version]
                [OUTPUT_NAME name]
                [OUTPUT_DIR dir]
               )

       

       This command creates a <target_name>.jar.  It compiles the given
       source files (source) and adds the given resource files (resource) to
       the jar file.  If only resource files are given then just a jar file
       is created.  The list of include jars are added to the classpath when
       compiling the java sources and also to the dependencies of the target.
       INCLUDE_JARS also accepts other target names created by add_jar.  For
       backwards compatibility, jar files listed as sources are ignored (as
       they have been since the first version of this module).

       The default OUTPUT_DIR can also be changed by setting the variable
       CMAKE_JAVA_TARGET_OUTPUT_DIR.

       Additional instructions:

          To add compile flags to the target you can set these flags with
          the following variable:

       

              set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)

       

          To add a path or a jar file to the class path you can do this
          with the CMAKE_JAVA_INCLUDE_PATH variable.

       

              set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)

       

          To use a different output name for the target you can set it with:

       

              add_jar(foobar foobar.java OUTPUT_NAME shibboleet.jar)

       

          To use a different output directory than CMAKE_CURRENT_BINARY_DIR
          you can set it with:

       

              add_jar(foobar foobar.java OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)

       

          To define an entry point in your jar you can set it with the ENTRY_POINT
          named argument:

       

              add_jar(example ENTRY_POINT com/examples/MyProject/Main)

       

          To add a VERSION to the target output name you can set it using
          the VERSION named argument to add_jar. This will create a jar file with the
          name shibboleet-1.0.0.jar and will create a symlink shibboleet.jar
          pointing to the jar with the version information.

       

              add_jar(shibboleet shibbotleet.java VERSION 1.2.0)

       

           If the target is a JNI library, utilize the following commands to
           create a JNI symbolic link:

       

              set(CMAKE_JNI_TARGET TRUE)
              add_jar(shibboleet shibbotleet.java VERSION 1.2.0)
              install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
              install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})

       

           If a single target needs to produce more than one jar from its
           java source code, to prevent the accumulation of duplicate class
           files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
           to calling the add_jar() function:

       

              set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
              add_jar(foo foo.java)

       

              set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar)
              add_jar(bar bar.java)

       

       Target Properties:

          The add_jar() functions sets some target properties. You can get these
          properties with the
             get_property(TARGET <target_name> PROPERTY <propery_name>)
          command.

       

          INSTALL_FILES      The files which should be installed. This is used by
                             install_jar().
          JNI_SYMLINK        The JNI symlink which should be installed.
                             This is used by install_jni_symlink().
          JAR_FILE           The location of the jar file so that you can include
                             it.
          CLASS_DIR          The directory where the class files can be found. For
                             example to use them with javah.

       

       find_jar(<VAR>

                 name | NAMES name1 [name2 ...]
                 [PATHS path1 [path2 ... ENV var]]
                 [VERSIONS version1 [version2]]
                 [DOC "cache documentation string"]
                )

       

       This command is used to find a full path to the named jar.  A cache
       entry named by <VAR> is created to stor the result of this command.
       If the full path to a jar is found the result is stored in the
       variable and the search will not repeated unless the variable is
       cleared.  If nothing is found, the result will be <VAR>-NOTFOUND, and
       the search will be attempted again next time find_jar is invoked with
       the same variable.  The name of the full path to a file that is
       searched for is specified by the names listed after NAMES argument.
       Additional search locations can be specified after the PATHS argument.
       If you require special a version of a jar file you can specify it with
       the VERSIONS argument.  The argument after DOC will be used for the
       documentation string in the cache.

       install_jar(TARGET_NAME DESTINATION)

       This command installs the TARGET_NAME files to the given DESTINATION.
       It should be called in the same scope as add_jar() or it will fail.

       install_jni_symlink(TARGET_NAME DESTINATION)

       This command installs the TARGET_NAME JNI symlinks to the given
       DESTINATION.  It should be called in the same scope as add_jar() or it
       will fail.

       create_javadoc(<VAR>

                       PACKAGES pkg1 [pkg2 ...]
                       [SOURCEPATH <sourcepath>]
                       [CLASSPATH <classpath>]

                       [AUTHOR TRUE|FALSE]
                       [USE TRUE|FALSE]
                       [VERSION TRUE|FALSE]
                      )

       

       Create java documentation based on files or packages.  For more
       details please read the javadoc manpage.

       There are two main signatures for create_javadoc.  The first signature
       works with package names on a path with source files:

          Example:
          create_javadoc(my_example_doc
            PACKAGES com.exmaple.foo com.example.bar
            SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}"
            CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
            WINDOWTITLE "My example"
            DOCTITLE "<h1>My example</h1>"
            AUTHOR TRUE
            USE TRUE
            VERSION TRUE
          )

       

       The second signature for create_javadoc works on a given list of
       files.

          create_javadoc(<VAR>
                         FILES file1 [file2 ...]
                         [CLASSPATH <classpath>]
                         [INSTALLPATH <install path>]
                         [DOCTITLE "the documentation title"]
                         [WINDOWTITLE "the title of the document"]
                         [AUTHOR TRUE|FALSE]
                         [USE TRUE|FALSE]
                         [VERSION TRUE|FALSE]
                        )

       

       Example:

          create_javadoc(my_example_doc
            FILES ${example_SRCS}
            CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
            WINDOWTITLE "My example"
            DOCTITLE "<h1>My example</h1>"
            AUTHOR TRUE
            USE TRUE
            VERSION TRUE
          )

       

       Both signatures share most of the options.  These options are the same
       as what you can find in the javadoc manpage.  Please look at the
       manpage for CLASSPATH, DOCTITLE, WINDOWTITLE, AUTHOR, USE and VERSION.

       The documentation will be by default installed to

          ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>

       

       if you don't set the INSTALLPATH.


  UseJavaClassFilelist
        

       

       This script create a list of compiled Java class files to be added to
       a jar file.  This avoids including cmake files which get created in
       the binary directory.


  UseJavaSymlinks
        

       

       Helper script for UseJava.cmake


  UsePkgConfig
       Obsolete pkg-config module for CMake, use FindPkgConfig instead.

       

       This module defines the following macro:

       PKGCONFIG(package includedir libdir linkflags cflags)

       Calling PKGCONFIG will fill the desired information into the 4 given
       arguments, e.g.  PKGCONFIG(libart-2.0 LIBART_INCLUDE_DIR
       LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS) if pkg-config was NOT
       found or the specified software package doesn't exist, the variable
       will be empty when the function returns, otherwise they will contain
       the respective information


  UseQt4
       Use Module for QT4

       Sets up C and C++ to use Qt 4.  It is assumed that FindQt.cmake has
       already been loaded.  See FindQt.cmake for information on how to load
       Qt 4 into your CMake project.

  UseSWIG
       SWIG module for CMake

       Defines the following macros:

          SWIG_ADD_MODULE(name language [ files ])
            - Define swig module with given name and specified language
          SWIG_LINK_LIBRARIES(name [ libraries ])
            - Link libraries to swig module

       All other macros are for internal use only.  To get the actual name of
       the swig module, use: ${SWIG_MODULE_${name}_REAL_NAME}.  Set Source
       files properties such as CPLUSPLUS and SWIG_FLAGS to specify special
       behavior of SWIG.  Also global CMAKE_SWIG_FLAGS can be used to add
       special flags to all swig calls.  Another special variable is
       CMAKE_SWIG_OUTDIR, it allows one to specify where to write all the
       swig generated module (swig -outdir option) The name-specific variable
       SWIG_MODULE_<name>_EXTRA_DEPS may be used to specify extra
       dependencies for the generated modules.  If the source file generated
       by swig need some special flag you can use
       set_source_files_properties( ${swig_generated_file_fullname}

               PROPERTIES COMPILE_FLAGS "-bla")

Policies

  CMP0000
       A minimum required CMake version must be specified.

       CMake requires that projects specify the version of CMake to which
       they have been written.  This policy has been put in place so users
       trying to build the project may be told when they need to update their
       CMake.  Specifying a version also helps the project build with CMake
       versions newer than that specified.  Use the cmake_minimum_required
       command at the top of your main CMakeLists.txt file:

         cmake_minimum_required(VERSION <major>.<minor>)

       where "<major>.<minor>" is the version of CMake you want to support
       (such as "2.6").  The command will ensure that at least the given
       version of CMake is running and help newer versions be compatible with
       the project.  See documentation of cmake_minimum_required for details.

       Note that the command invocation must appear in the CMakeLists.txt
       file itself; a call in an included file is not sufficient.  However,
       the cmake_policy command may be called to set policy CMP0000 to OLD or
       NEW behavior explicitly.  The OLD behavior is to silently ignore the
       missing invocation.  The NEW behavior is to issue an error instead of
       a warning.  An included file may set CMP0000 explicitly to affect how
       this policy is enforced for the main CMakeLists.txt file.

       This policy was introduced in CMake version 2.6.0.

  CMP0001
       CMAKE_BACKWARDS_COMPATIBILITY should no longer be used.

       The OLD behavior is to check CMAKE_BACKWARDS_COMPATIBILITY and present
       it to the user.  The NEW behavior is to ignore
       CMAKE_BACKWARDS_COMPATIBILITY completely.

       In CMake 2.4 and below the variable CMAKE_BACKWARDS_COMPATIBILITY was
       used to request compatibility with earlier versions of CMake.  In
       CMake 2.6 and above all compatibility issues are handled by policies
       and the cmake_policy command.  However, CMake must still check
       CMAKE_BACKWARDS_COMPATIBILITY for projects written for CMake 2.4 and
       below.

       This policy was introduced in CMake version 2.6.0.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0002
       Logical target names must be globally unique.

       Targets names created with add_executable, add_library, or
       add_custom_target are logical build target names.  Logical target
       names must be globally unique because:

         - Unique names may be referenced unambiguously both in CMake
           code and on make tool command lines.
         - Logical names are used by Xcode and VS IDE generators
           to produce meaningful project names for the targets.

       The logical name of executable and library targets does not have to
       correspond to the physical file names built.  Consider using the
       OUTPUT_NAME target property to create two targets with the same
       physical name while keeping logical names distinct.  Custom targets
       must simply have globally unique names (unless one uses the global
       property ALLOW_DUPLICATE_CUSTOM_TARGETS with a Makefiles generator).

       This policy was introduced in CMake version 2.6.0.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0003
       Libraries linked via full path no longer produce linker search paths.

       This policy affects how libraries whose full paths are NOT known are
       found at link time, but was created due to a change in how CMake deals
       with libraries whose full paths are known.  Consider the code

         target_link_libraries(myexe /path/to/libA.so)

       CMake 2.4 and below implemented linking to libraries whose full paths
       are known by splitting them on the link line into separate components
       consisting of the linker search path and the library name.  The
       example code might have produced something like

         ... -L/path/to -lA ...

       in order to link to library A.  An analysis was performed to order
       multiple link directories such that the linker would find library A in
       the desired location, but there are cases in which this does not work.
       CMake versions 2.6 and above use the more reliable approach of passing
       the full path to libraries directly to the linker in most cases.  The
       example code now produces something like

         ... /path/to/libA.so ....

       Unfortunately this change can break code like

         target_link_libraries(myexe /path/to/libA.so B)

       where "B" is meant to find "/path/to/libB.so".  This code is wrong
       because the user is asking the linker to find library B but has not
       provided a linker search path (which may be added with the
       link_directories command).  However, with the old linking
       implementation the code would work accidentally because the linker
       search path added for library A allowed library B to be found.

       In order to support projects depending on linker search paths added by
       linking to libraries with known full paths, the OLD behavior for this
       policy will add the linker search paths even though they are not
       needed for their own libraries.  When this policy is set to OLD, CMake
       will produce a link line such as

         ... -L/path/to /path/to/libA.so -lB ...

       which will allow library B to be found as it was previously.  When
       this policy is set to NEW, CMake will produce a link line such as

         ... /path/to/libA.so -lB ...

       which more accurately matches what the project specified.

       The setting for this policy used when generating the link line is that
       in effect when the target is created by an add_executable or
       add_library command.  For the example described above, the code

         cmake_policy(SET CMP0003 OLD) # or cmake_policy(VERSION 2.4)
         add_executable(myexe myexe.c)
         target_link_libraries(myexe /path/to/libA.so B)

       will work and suppress the warning for this policy.  It may also be
       updated to work with the corrected linking approach:

         cmake_policy(SET CMP0003 NEW) # or cmake_policy(VERSION 2.6)
         link_directories(/path/to) # needed to find library B
         add_executable(myexe myexe.c)
         target_link_libraries(myexe /path/to/libA.so B)

       Even better, library B may be specified with a full path:

         add_executable(myexe myexe.c)
         target_link_libraries(myexe /path/to/libA.so /path/to/libB.so)

       When all items on the link line have known paths CMake does not check
       this policy so it has no effect.

       Note that the warning for this policy will be issued for at most one
       target.  This avoids flooding users with messages for every target
       when setting the policy once will probably fix all targets.

       This policy was introduced in CMake version 2.6.0.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0004
       Libraries linked may not have leading or trailing whitespace.

       CMake versions 2.4 and below silently removed leading and trailing
       whitespace from libraries linked with code like

         target_link_libraries(myexe " A ")

       This could lead to subtle errors in user projects.

       The OLD behavior for this policy is to silently remove leading and
       trailing whitespace.  The NEW behavior for this policy is to diagnose
       the existence of such whitespace as an error.  The setting for this
       policy used when checking the library names is that in effect when the
       target is created by an add_executable or add_library command.

       This policy was introduced in CMake version 2.6.0.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0005
       Preprocessor definition values are now escaped automatically.

       This policy determines whether or not CMake should generate escaped
       preprocessor definition values added via add_definitions.  CMake
       versions 2.4 and below assumed that only trivial values would be given
       for macros in add_definitions calls.  It did not attempt to escape
       non-trivial values such as string literals in generated build rules.
       CMake versions 2.6 and above support escaping of most values, but
       cannot assume the user has not added escapes already in an attempt to
       work around limitations in earlier versions.

       The OLD behavior for this policy is to place definition values given
       to add_definitions directly in the generated build rules without
       attempting to escape anything.  The NEW behavior for this policy is to
       generate correct escapes for all native build tools automatically.
       See documentation of the COMPILE_DEFINITIONS target property for
       limitations of the escaping implementation.

       This policy was introduced in CMake version 2.6.0.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0006
       Installing MACOSX_BUNDLE targets requires a BUNDLE DESTINATION.

       This policy determines whether the install(TARGETS) command must be
       given a BUNDLE DESTINATION when asked to install a target with the
       MACOSX_BUNDLE property set.  CMake 2.4 and below did not distinguish
       application bundles from normal executables when installing targets.
       CMake 2.6 provides a BUNDLE option to the install(TARGETS) command
       that specifies rules specific to application bundles on the Mac.
       Projects should use this option when installing a target with the
       MACOSX_BUNDLE property set.

       The OLD behavior for this policy is to fall back to the RUNTIME
       DESTINATION if a BUNDLE DESTINATION is not given.  The NEW behavior
       for this policy is to produce an error if a bundle target is installed
       without a BUNDLE DESTINATION.

       This policy was introduced in CMake version 2.6.0.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0007
       list command no longer ignores empty elements.

       This policy determines whether the list command will ignore empty
       elements in the list.  CMake 2.4 and below list commands ignored all
       empty elements in the list.  For example, a;b;;c would have length 3
       and not 4.  The OLD behavior for this policy is to ignore empty list
       elements.  The NEW behavior for this policy is to correctly count
       empty elements in a list.

       This policy was introduced in CMake version 2.6.0.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0008
       Libraries linked by full-path must have a valid library file name.

       In CMake 2.4 and below it is possible to write code like

         target_link_libraries(myexe /full/path/to/somelib)

       where "somelib" is supposed to be a valid library file name such as
       "libsomelib.a" or "somelib.lib".  For Makefile generators this
       produces an error at build time because the dependency on the full
       path cannot be found.  For VS IDE and Xcode generators this used to
       work by accident because CMake would always split off the library
       directory and ask the linker to search for the library by name
       (-lsomelib or somelib.lib).  Despite the failure with Makefiles, some
       projects have code like this and build only with VS and/or Xcode.
       This version of CMake prefers to pass the full path directly to the
       native build tool, which will fail in this case because it does not
       name a valid library file.

       This policy determines what to do with full paths that do not appear
       to name a valid library file.  The OLD behavior for this policy is to
       split the library name from the path and ask the linker to search for
       it.  The NEW behavior for this policy is to trust the given path and
       pass it directly to the native build tool unchanged.

       This policy was introduced in CMake version 2.6.1.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0009
       FILE GLOB_RECURSE calls should not follow symlinks by default.

       In CMake 2.6.1 and below, FILE GLOB_RECURSE calls would follow through
       symlinks, sometimes coming up with unexpectedly large result sets
       because of symlinks to top level directories that contain hundreds of
       thousands of files.

       This policy determines whether or not to follow symlinks encountered
       during a FILE GLOB_RECURSE call.  The OLD behavior for this policy is
       to follow the symlinks.  The NEW behavior for this policy is not to
       follow the symlinks by default, but only if FOLLOW_SYMLINKS is given
       as an additional argument to the FILE command.

       This policy was introduced in CMake version 2.6.2.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0010
       Bad variable reference syntax is an error.

       In CMake 2.6.2 and below, incorrect variable reference syntax such as
       a missing close-brace ("${FOO") was reported but did not stop
       processing of CMake code.  This policy determines whether a bad
       variable reference is an error.  The OLD behavior for this policy is
       to warn about the error, leave the string untouched, and continue.
       The NEW behavior for this policy is to report an error.

       This policy was introduced in CMake version 2.6.3.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0011
       Included scripts do automatic cmake_policy PUSH and POP.

       In CMake 2.6.2 and below, CMake Policy settings in scripts loaded by
       the include() and find_package() commands would affect the includer.
       Explicit invocations of cmake_policy(PUSH) and cmake_policy(POP) were
       required to isolate policy changes and protect the includer.  While
       some scripts intend to affect the policies of their includer, most do
       not.  In CMake 2.6.3 and above, include() and find_package() by
       default PUSH and POP an entry on the policy stack around an included
       script, but provide a NO_POLICY_SCOPE option to disable it.  This
       policy determines whether or not to imply NO_POLICY_SCOPE for
       compatibility.  The OLD behavior for this policy is to imply
       NO_POLICY_SCOPE for include() and find_package() commands.  The NEW
       behavior for this policy is to allow the commands to do their default
       cmake_policy PUSH and POP.

       This policy was introduced in CMake version 2.6.3.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0012
       if() recognizes numbers and boolean constants.

       In CMake versions 2.6.4 and lower the if() command implicitly
       dereferenced arguments corresponding to variables, even those named
       like numbers or boolean constants, except for 0 and 1.  Numbers and
       boolean constants such as true, false, yes, no, on, off, y, n,
       notfound, ignore (all case insensitive) were recognized in some cases
       but not all.  For example, the code "if(TRUE)" might have evaluated as
       false.  Numbers such as 2 were recognized only in boolean expressions
       like "if(NOT 2)" (leading to false) but not as a single-argument like
       "if(2)" (also leading to false).  Later versions of CMake prefer to
       treat numbers and boolean constants literally, so they should not be
       used as variable names.

       The OLD behavior for this policy is to implicitly dereference
       variables named like numbers and boolean constants.  The NEW behavior
       for this policy is to recognize numbers and boolean constants without
       dereferencing variables with such names.

       This policy was introduced in CMake version 2.8.0.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0013
       Duplicate binary directories are not allowed.

       CMake 2.6.3 and below silently permitted add_subdirectory() calls to
       create the same binary directory multiple times.  During build system
       generation files would be written and then overwritten in the build
       tree and could lead to strange behavior.  CMake 2.6.4 and above
       explicitly detect duplicate binary directories.  CMake 2.6.4 always
       considers this case an error.  In CMake 2.8.0 and above this policy
       determines whether or not the case is an error.  The OLD behavior for
       this policy is to allow duplicate binary directories.  The NEW
       behavior for this policy is to disallow duplicate binary directories
       with an error.

       This policy was introduced in CMake version 2.8.0.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0014
       Input directories must have CMakeLists.txt.

       CMake versions before 2.8 silently ignored missing CMakeLists.txt
       files in directories referenced by add_subdirectory() or subdirs(),
       treating them as if present but empty.  In CMake 2.8.0 and above this
       policy determines whether or not the case is an error.  The OLD
       behavior for this policy is to silently ignore the problem.  The NEW
       behavior for this policy is to report an error.

       This policy was introduced in CMake version 2.8.0.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0015
       link_directories() treats paths relative to the source dir.

       In CMake 2.8.0 and lower the link_directories() command passed
       relative paths unchanged to the linker.  In CMake 2.8.1 and above the
       link_directories() command prefers to interpret relative paths with
       respect to CMAKE_CURRENT_SOURCE_DIR, which is consistent with
       include_directories() and other commands.  The OLD behavior for this
       policy is to use relative paths verbatim in the linker command.  The
       NEW behavior for this policy is to convert relative paths to absolute
       paths by appending the relative path to CMAKE_CURRENT_SOURCE_DIR.

       This policy was introduced in CMake version 2.8.1.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0016
       target_link_libraries() reports error if its only argument is not a
       target.

       In CMake 2.8.2 and lower the target_link_libraries() command silently
       ignored if it was called with only one argument, and this argument
       wasn't a valid target.  In CMake 2.8.3 and above it reports an error
       in this case.

       This policy was introduced in CMake version 2.8.3.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0017
       Prefer files from the CMake module directory when including from
       there.

       Starting with CMake 2.8.4, if a cmake-module shipped with CMake (i.e.
       located in the CMake module directory) calls include() or
       find_package(), the files located in the CMake module directory are
       preferred over the files in CMAKE_MODULE_PATH.  This makes sure that
       the modules belonging to CMake always get those files included which
       they expect, and against which they were developed and tested.  In all
       other cases, the files found in CMAKE_MODULE_PATH still take
       precedence over the ones in the CMake module directory.  The OLD
       behaviour is to always prefer files from CMAKE_MODULE_PATH over files
       from the CMake modules directory.

       This policy was introduced in CMake version 2.8.4.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0018
       Ignore CMAKE_SHARED_LIBRARY_<Lang>_FLAGS variable.

       CMake 2.8.8 and lower compiled sources in SHARED and MODULE libraries
       using the value of the undocumented CMAKE_SHARED_LIBRARY_<Lang>_FLAGS
       platform variable.  The variable contained platform-specific flags
       needed to compile objects for shared libraries.  Typically it included
       a flag such as -fPIC for position independent code but also included
       other flags needed on certain platforms.  CMake 2.8.9 and higher
       prefer instead to use the POSITION_INDEPENDENT_CODE target property to
       determine what targets should be position independent, and new
       undocumented platform variables to select flags while ignoring
       CMAKE_SHARED_LIBRARY_<Lang>_FLAGS completely.

       The default for either approach produces identical compilation flags,
       but if a project modifies CMAKE_SHARED_LIBRARY_<Lang>_FLAGS from its
       original value this policy determines which approach to use.

       The OLD behavior for this policy is to ignore the
       POSITION_INDEPENDENT_CODE property for all targets and use the
       modified value of CMAKE_SHARED_LIBRARY_<Lang>_FLAGS for SHARED and
       MODULE libraries.

       The NEW behavior for this policy is to ignore
       CMAKE_SHARED_LIBRARY_<Lang>_FLAGS whether it is modified or not and
       honor the POSITION_INDEPENDENT_CODE target property.

       This policy was introduced in CMake version 2.8.9.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0019
       Do not re-expand variables in include and link information.

       CMake 2.8.10 and lower re-evaluated values given to the
       include_directories, link_directories, and link_libraries commands to
       expand any leftover variable references at the end of the
       configuration step.  This was for strict compatibility with VERY early
       CMake versions because all variable references are now normally
       evaluated during CMake language processing.  CMake 2.8.11 and higher
       prefer to skip the extra evaluation.

       The OLD behavior for this policy is to re-evaluate the values for
       strict compatibility.  The NEW behavior for this policy is to leave
       the values untouched.

       This policy was introduced in CMake version 2.8.11.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0020
       Automatically link Qt executables to qtmain target on Windows.

       CMake 2.8.10 and lower required users of Qt to always specify a link
       dependency to the qtmain.lib static library manually on Windows.
       CMake 2.8.11 gained the ability to evaluate generator expressions
       while determining the link dependencies from IMPORTED targets.  This
       allows CMake itself to automatically link executables which link to Qt
       to the qtmain.lib library when using IMPORTED Qt targets.  For
       applications already linking to qtmain.lib, this should have little
       impact.  For applications which supply their own alternative WinMain
       implementation and for applications which use the QAxServer library,
       this automatic linking will need to be disabled as per the
       documentation.

       The OLD behavior for this policy is not to link executables to
       qtmain.lib automatically when they link to the QtCore IMPORTEDtarget.
       The NEW behavior for this policy is to link executables to qtmain.lib
       automatically when they link to QtCore IMPORTED target.

       This policy was introduced in CMake version 2.8.11.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0021
       Fatal error on relative paths in INCLUDE_DIRECTORIES target property.

       CMake 2.8.10.2 and lower allowed the INCLUDE_DIRECTORIES target
       property to contain relative paths.  The base path for such relative
       entries is not well defined.  CMake 2.8.12 issues a FATAL_ERROR if the
       INCLUDE_DIRECTORIES property contains a relative path.

       The OLD behavior for this policy is not to warn about relative paths
       in the INCLUDE_DIRECTORIES target property.  The NEW behavior for this
       policy is to issue a FATAL_ERROR if INCLUDE_DIRECTORIES contains a
       relative path.

       This policy was introduced in CMake version 2.8.12.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0022
       INTERFACE_LINK_LIBRARIES defines the link interface.

       CMake 2.8.11 constructed the 'link interface' of a target from
       properties matching (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)?.
       The modern way to specify config-sensitive content is to use generator
       expressions and the IMPORTED_ prefix makes uniform processing of the
       link interface with generator expressions impossible.  The
       INTERFACE_LINK_LIBRARIES target property was introduced as a
       replacement in CMake 2.8.12.  This new property is named consistently
       with the INTERFACE_COMPILE_DEFINITIONS, INTERFACE_INCLUDE_DIRECTORIES
       and INTERFACE_COMPILE_OPTIONS properties.  For in-build targets, CMake
       will use the INTERFACE_LINK_LIBRARIES property as the source of the
       link interface only if policy CMP0022 is NEW.  When exporting a target
       which has this policy set to NEW, only the INTERFACE_LINK_LIBRARIES
       property will be processed and generated for the IMPORTED target by
       default.  A new option to the install(EXPORT) and export commands
       allows export of the old-style properties for compatibility with
       downstream users of CMake versions older than 2.8.12.  The
       target_link_libraries command will no longer populate the properties
       matching LINK_INTERFACE_LIBRARIES(_<CONFIG>)? if this policy is NEW.

       The OLD behavior for this policy is to ignore the
       INTERFACE_LINK_LIBRARIES property for in-build targets.  The NEW
       behavior for this policy is to use the INTERFACE_LINK_LIBRARIES
       property for in-build targets, and ignore the old properties matching
       (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)?.

       This policy was introduced in CMake version 2.8.12.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

  CMP0023
       Plain and keyword target_link_libraries signatures cannot be mixed.

       CMake 2.8.12 introduced the target_link_libraries signature using the
       PUBLIC, PRIVATE, and INTERFACE keywords to generalize the LINK_PUBLIC
       and LINK_PRIVATE keywords introduced in CMake 2.8.7.  Use of
       signatures with any of these keywords sets the link interface of a
       target explicitly, even if empty.  This produces confusing behavior
       when used in combination with the historical behavior of the plain
       target_link_libraries signature.  For example, consider the code:

        target_link_libraries(mylib A)
        target_link_libraries(mylib PRIVATE B)

       After the first line the link interface has not been set explicitly so
       CMake would use the link implementation, A, as the link interface.
       However, the second line sets the link interface to empty.  In order
       to avoid this subtle behavior CMake now prefers to disallow mixing the
       plain and keyword signatures of target_link_libraries for a single
       target.

       The OLD behavior for this policy is to allow keyword and plain
       target_link_libraries signatures to be mixed.  The NEW behavior for
       this policy is to not to allow mixing of the keyword and plain
       signatures.

       This policy was introduced in CMake version 2.8.12.  CMake version
       2.8.12.1 warns when the policy is not set and uses OLD behavior.  Use
       the cmake_policy command to set it to OLD or NEW explicitly.

------------------------------------------------------------------------------
Variables

------------------------------------------------------------------------------
Variables That Change Behavior

  BUILD_SHARED_LIBS
       Global flag to cause add_library to create shared libraries if on.

       If present and true, this will cause all libraries to be built shared
       unless the library was explicitly added as a static library.  This
       variable is often added to projects as an OPTION so that each user of
       a project can decide if they want to build the project using shared or
       static libraries.

  CMAKE_ABSOLUTE_DESTINATION_FILES
       List of files which have been installed using an ABSOLUTE DESTINATION
       path.

       This variable is defined by CMake-generated cmake_install.cmake
       scripts.  It can be used (read-only) by programs or scripts that
       source those install scripts.  This is used by some CPack generators
       (e.g.  RPM).

  CMAKE_AUTOMOC_RELAXED_MODE
       Switch between strict and relaxed automoc mode.

       By default, automoc behaves exactly as described in the documentation
       of the AUTOMOC target property.  When set to TRUE, it accepts more
       input and tries to find the correct input file for moc even if it
       differs from the documented behaviour.  In this mode it e.g.  also
       checks whether a header file is intended to be processed by moc when a
       "foo.moc" file has been included.

       Relaxed mode has to be enabled for KDE4 compatibility.

  CMAKE_BACKWARDS_COMPATIBILITY
       Version of cmake required to build project

       From the point of view of backwards compatibility, this specifies what
       version of CMake should be supported.  By default this value is the
       version number of CMake that you are running.  You can set this to an
       older version of CMake to support deprecated commands of CMake in
       projects that were written to use older versions of CMake.  This can
       be set by the user or set at the beginning of a CMakeLists file.

  CMAKE_BUILD_TYPE
       Specifies the build type on single-configuration generators.

       This statically specifies what build type (configuration) will be
       built in this build tree.  Possible values are empty, Debug, Release,
       RelWithDebInfo and MinSizeRel.  This variable is only meaningful to
       single-configuration generators (such as make and Ninja) i.e.  those
       which choose a single configuration when CMake runs to generate a
       build tree as opposed to multi-configuration generators which offer
       selection of the build configuration within the generated build
       environment.  There are many per-config properties and variables
       (usually following clean SOME_VAR_<CONFIG> order conventions), such as
       CMAKE_C_FLAGS_<CONFIG>, specified as uppercase:
       CMAKE_C_FLAGS_[DEBUG|RELEASE|RELWITHDEBINFO|MINSIZEREL].  For example,
       in a build tree configured to build type Debug, CMake will see to
       having CMAKE_C_FLAGS_DEBUG settings get added to the CMAKE_C_FLAGS
       settings.  See also CMAKE_CONFIGURATION_TYPES.

  CMAKE_COLOR_MAKEFILE
       Enables color output when using the Makefile generator.

       When enabled, the generated Makefiles will produce colored output.
       Default is ON.

  CMAKE_CONFIGURATION_TYPES
       Specifies the available build types on multi-config generators.

       This specifies what build types (configurations) will be available
       such as Debug, Release, RelWithDebInfo etc.  This has reasonable
       defaults on most platforms, but can be extended to provide other build
       types.  See also CMAKE_BUILD_TYPE for details of managing
       configuration data, and CMAKE_CFG_INTDIR.

  CMAKE_DEBUG_TARGET_PROPERTIES
       Enables tracing output for target properties.

       This variable can be populated with a list of properties to generate
       debug output for when evaluating target properties.  Currently it can
       only be used when evaluating the INCLUDE_DIRECTORIES,
       COMPILE_DEFINITIONS and COMPILE_OPTIONS target properties.  In that
       case, it outputs a backtrace for each entry in the target property.
       Default is unset.

  CMAKE_DISABLE_FIND_PACKAGE_<PackageName>
       Variable for disabling find_package() calls.

       Every non-REQUIRED find_package() call in a project can be disabled by
       setting the variable CMAKE_DISABLE_FIND_PACKAGE_<PackageName> to TRUE.
       This can be used to build a project without an optional package,
       although that package is installed.

       This switch should be used during the initial CMake run.  Otherwise if
       the package has already been found in a previous CMake run, the
       variables which have been stored in the cache will still be there.  In
       that case it is recommended to remove the cache variables for this
       package from the cache using the cache editor or cmake -U

  CMAKE_ERROR_DEPRECATED
       Whether to issue deprecation errors for macros and functions.

       If TRUE, this can be used by macros and functions to issue fatal
       errors when deprecated macros or functions are used.  This variable is
       FALSE by default.

  CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
       Ask cmake_install.cmake script to error out as soon as a file with
       absolute INSTALL DESTINATION is encountered.

       The fatal error is emitted before the installation of the offending
       file takes place.  This variable is used by CMake-generated
       cmake_install.cmake scripts.  If one sets this variable to ON while
       running the script, it may get fatal error messages from the script.

  CMAKE_FIND_LIBRARY_PREFIXES
       Prefixes to prepend when looking for libraries.

       This specifies what prefixes to add to library names when the
       find_library command looks for libraries.  On UNIX systems this is
       typically lib, meaning that when trying to find the foo library it
       will look for libfoo.

  CMAKE_FIND_LIBRARY_SUFFIXES
       Suffixes to append when looking for libraries.

       This specifies what suffixes to add to library names when the
       find_library command looks for libraries.  On Windows systems this is
       typically .lib and .dll, meaning that when trying to find the foo
       library it will look for foo.dll etc.

  CMAKE_FIND_PACKAGE_WARN_NO_MODULE
       Tell find_package to warn if called without an explicit mode.

       If find_package is called without an explicit mode option (MODULE,
       CONFIG or NO_MODULE) and no Find<pkg>.cmake module is in
       CMAKE_MODULE_PATH then CMake implicitly assumes that the caller
       intends to search for a package configuration file.  If no package
       configuration file is found then the wording of the failure message
       must account for both the case that the package is really missing and
       the case that the project has a bug and failed to provide the intended
       Find module.  If instead the caller specifies an explicit mode option
       then the failure message can be more specific.

       Set CMAKE_FIND_PACKAGE_WARN_NO_MODULE to TRUE to tell find_package to
       warn when it implicitly assumes Config mode.  This helps developers
       enforce use of an explicit mode in all calls to find_package within a
       project.

  CMAKE_IGNORE_PATH
       Path to be ignored by FIND_XXX() commands.

       Specifies directories to be ignored by searches in FIND_XXX()
       commands.  This is useful in cross-compiled environments where some
       system directories contain incompatible but possibly linkable
       libraries.  For example, on cross-compiled cluster environments, this
       allows a user to ignore directories containing libraries meant for the
       front-end machine that modules like FindX11 (and others) would
       normally search.  By default this is empty; it is intended to be set
       by the project.  Note that CMAKE_IGNORE_PATH takes a list of directory
       names, NOT a list of prefixes.  If you want to ignore paths under
       prefixes (bin, include, lib, etc.), you'll need to specify them
       explicitly.  See also CMAKE_PREFIX_PATH, CMAKE_LIBRARY_PATH,
       CMAKE_INCLUDE_PATH, CMAKE_PROGRAM_PATH.

  CMAKE_INCLUDE_PATH
       Path used for searching by FIND_FILE() and FIND_PATH().

       Specifies a path which will be used both by FIND_FILE() and
       FIND_PATH().  Both commands will check each of the contained
       directories for the existence of the file which is currently searched.
       By default it is empty, it is intended to be set by the project.  See
       also CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_PREFIX_PATH.

  CMAKE_INSTALL_DEFAULT_COMPONENT_NAME
       Default component used in install() commands.

       If an install() command is used without the COMPONENT argument, these
       files will be grouped into a default component.  The name of this
       default install component will be taken from this variable.  It
       defaults to "Unspecified".

  CMAKE_INSTALL_PREFIX
       Install directory used by install.

       If "make install" is invoked or INSTALL is built, this directory is
       prepended onto all install directories.  This variable defaults to
       /usr/local on UNIX and c:/Program Files on Windows.

       On UNIX one can use the DESTDIR mechanism in order to relocate the
       whole installation.  DESTDIR means DESTination DIRectory.  It is
       commonly used by makefile users in order to install software at
       non-default location.  It is usually invoked like this:

        make DESTDIR=/home/john install

       which will install the concerned software using the installation
       prefix, e.g.  "/usr/local" prepended with the DESTDIR value which
       finally gives "/home/john/usr/local".

       WARNING: DESTDIR may not be used on Windows because installation
       prefix usually contains a drive letter like in "C:/Program Files"
       which cannot be prepended with some other prefix.

       The installation prefix is also added to CMAKE_SYSTEM_PREFIX_PATH so
       that find_package, find_program, find_library, find_path, and
       find_file will search the prefix for other software.

  CMAKE_LIBRARY_PATH
       Path used for searching by FIND_LIBRARY().

       Specifies a path which will be used by FIND_LIBRARY().  FIND_LIBRARY()
       will check each of the contained directories for the existence of the
       library which is currently searched.  By default it is empty, it is
       intended to be set by the project.  See also
       CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_PREFIX_PATH.

  CMAKE_MFC_FLAG
       Tell cmake to use MFC for an executable or dll.

       This can be set in a CMakeLists.txt file and will enable MFC in the
       application.  It should be set to 1 for the static MFC library, and 2
       for the shared MFC library.  This is used in Visual Studio 6 and 7
       project files.  The CMakeSetup dialog used MFC and the CMakeLists.txt
       looks like this:

         add_definitions(-D_AFXDLL)
         set(CMAKE_MFC_FLAG 2)
         add_executable(CMakeSetup WIN32 ${SRCS})


  CMAKE_MODULE_PATH
       List of directories to search for CMake modules.

       Commands like include() and find_package() search for files in
       directories listed by this variable before checking the default
       modules that come with CMake.

  CMAKE_NOT_USING_CONFIG_FLAGS
       Skip _BUILD_TYPE flags if true.

       This is an internal flag used by the generators in CMake to tell CMake
       to skip the _BUILD_TYPE flags.

  CMAKE_POLICY_DEFAULT_CMP<NNNN>
       Default for CMake Policy CMP<NNNN> when it is otherwise left unset.

       Commands cmake_minimum_required(VERSION) and cmake_policy(VERSION) by
       default leave policies introduced after the given version unset.  Set
       CMAKE_POLICY_DEFAULT_CMP<NNNN> to OLD or NEW to specify the default
       for policy CMP<NNNN>, where <NNNN> is the policy number.

       This variable should not be set by a project in CMake code; use
       cmake_policy(SET) instead.  Users running CMake may set this variable
       in the cache (e.g.  -DCMAKE_POLICY_DEFAULT_CMP<NNNN>=<OLD|NEW>) to set
       a policy not otherwise set by the project.  Set to OLD to quiet a
       policy warning while using old behavior or to NEW to try building the
       project with new behavior.

  CMAKE_PREFIX_PATH
       Path used for searching by FIND_XXX(), with appropriate suffixes
       added.

       Specifies a path which will be used by the FIND_XXX() commands.  It
       contains the "base" directories, the FIND_XXX() commands append
       appropriate subdirectories to the base directories.  So FIND_PROGRAM()
       adds /bin to each of the directories in the path, FIND_LIBRARY()
       appends /lib to each of the directories, and FIND_PATH() and
       FIND_FILE() append /include .  By default it is empty, it is intended
       to be set by the project.  See also CMAKE_SYSTEM_PREFIX_PATH,
       CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH.

  CMAKE_PROGRAM_PATH
       Path used for searching by FIND_PROGRAM().

       Specifies a path which will be used by FIND_PROGRAM().  FIND_PROGRAM()
       will check each of the contained directories for the existence of the
       program which is currently searched.  By default it is empty, it is
       intended to be set by the project.  See also
       CMAKE_SYSTEM_PROGRAM_PATH, CMAKE_PREFIX_PATH.

  CMAKE_SKIP_INSTALL_ALL_DEPENDENCY
       Don't make the install target depend on the all target.

       By default, the "install" target depends on the "all" target.  This
       has the effect, that when "make install" is invoked or INSTALL is
       built, first the "all" target is built, then the installation starts.
       If CMAKE_SKIP_INSTALL_ALL_DEPENDENCY is set to TRUE, this dependency
       is not created, so the installation process will start immediately,
       independent from whether the project has been completely built or not.

  CMAKE_SYSTEM_IGNORE_PATH
       Path to be ignored by FIND_XXX() commands.

       Specifies directories to be ignored by searches in FIND_XXX()
       commands.  This is useful in cross-compiled environments where some
       system directories contain incompatible but possibly linkable
       libraries.  For example, on cross-compiled cluster environments, this
       allows a user to ignore directories containing libraries meant for the
       front-end machine that modules like FindX11 (and others) would
       normally search.  By default this contains a list of directories
       containing incompatible binaries for the host system.  See also
       CMAKE_SYSTEM_PREFIX_PATH, CMAKE_SYSTEM_LIBRARY_PATH,
       CMAKE_SYSTEM_INCLUDE_PATH, and CMAKE_SYSTEM_PROGRAM_PATH.

  CMAKE_SYSTEM_INCLUDE_PATH
       Path used for searching by FIND_FILE() and FIND_PATH().

       Specifies a path which will be used both by FIND_FILE() and
       FIND_PATH().  Both commands will check each of the contained
       directories for the existence of the file which is currently searched.
       By default it contains the standard directories for the current
       system.  It is NOT intended to be modified by the project, use
       CMAKE_INCLUDE_PATH for this.  See also CMAKE_SYSTEM_PREFIX_PATH.

  CMAKE_SYSTEM_LIBRARY_PATH
       Path used for searching by FIND_LIBRARY().

       Specifies a path which will be used by FIND_LIBRARY().  FIND_LIBRARY()
       will check each of the contained directories for the existence of the
       library which is currently searched.  By default it contains the
       standard directories for the current system.  It is NOT intended to be
       modified by the project, use CMAKE_LIBRARY_PATH for this.  See also
       CMAKE_SYSTEM_PREFIX_PATH.

  CMAKE_SYSTEM_PREFIX_PATH
       Path used for searching by FIND_XXX(), with appropriate suffixes
       added.

       Specifies a path which will be used by the FIND_XXX() commands.  It
       contains the "base" directories, the FIND_XXX() commands append
       appropriate subdirectories to the base directories.  So FIND_PROGRAM()
       adds /bin to each of the directories in the path, FIND_LIBRARY()
       appends /lib to each of the directories, and FIND_PATH() and
       FIND_FILE() append /include .  By default this contains the standard
       directories for the current system and the CMAKE_INSTALL_PREFIX.  It
       is NOT intended to be modified by the project, use CMAKE_PREFIX_PATH
       for this.  See also CMAKE_SYSTEM_INCLUDE_PATH,
       CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_SYSTEM_PROGRAM_PATH, and
       CMAKE_SYSTEM_IGNORE_PATH.

  CMAKE_SYSTEM_PROGRAM_PATH
       Path used for searching by FIND_PROGRAM().

       Specifies a path which will be used by FIND_PROGRAM().  FIND_PROGRAM()
       will check each of the contained directories for the existence of the
       program which is currently searched.  By default it contains the
       standard directories for the current system.  It is NOT intended to be
       modified by the project, use CMAKE_PROGRAM_PATH for this.  See also
       CMAKE_SYSTEM_PREFIX_PATH.

  CMAKE_USER_MAKE_RULES_OVERRIDE
       Specify a CMake file that overrides platform information.

       CMake loads the specified file while enabling support for each
       language from either the project() or enable_language() commands.  It
       is loaded after CMake's builtin compiler and platform information
       modules have been loaded but before the information is used.  The file
       may set platform information variables to override CMake's defaults.

       This feature is intended for use only in overriding information
       variables that must be set before CMake builds its first test project
       to check that the compiler for a language works.  It should not be
       used to load a file in cases that a normal include() will work.  Use
       it only as a last resort for behavior that cannot be achieved any
       other way.  For example, one may set CMAKE_C_FLAGS_INIT to change the
       default value used to initialize CMAKE_C_FLAGS before it is cached.
       The override file should NOT be used to set anything that could be set
       after languages are enabled, such as variables like
       CMAKE_RUNTIME_OUTPUT_DIRECTORY that affect the placement of binaries.
       Information set in the file will be used for try_compile and try_run
       builds too.

  CMAKE_WARN_DEPRECATED
       Whether to issue deprecation warnings for macros and functions.

       If TRUE, this can be used by macros and functions to issue deprecation
       warnings.  This variable is FALSE by default.

  CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
       Ask cmake_install.cmake script to warn each time a file with absolute
       INSTALL DESTINATION is encountered.

       This variable is used by CMake-generated cmake_install.cmake scripts.
       If one sets this variable to ON while running the script, it may get
       warning messages from the script.

------------------------------------------------------------------------------
Variables That Describe the System

  APPLE
       True if running on Mac OS X.

       Set to true on Mac OS X.

  BORLAND
       True if the Borland compiler is being used.

       This is set to true if the Borland compiler is being used.

  CMAKE_CL_64
       Using the 64 bit compiler from Microsoft

       Set to true when using the 64 bit cl compiler from Microsoft.

  CMAKE_COMPILER_2005
       Using the Visual Studio 2005 compiler from Microsoft

       Set to true when using the Visual Studio 2005 compiler from Microsoft.

  CMAKE_HOST_APPLE
       True for Apple OS X operating systems.

       Set to true when the host system is Apple OS X.

  CMAKE_HOST_SYSTEM
       Name of system cmake is being run on.

       The same as CMAKE_SYSTEM but for the host system instead of the target
       system when cross compiling.

  CMAKE_HOST_SYSTEM_NAME
       Name of the OS CMake is running on.

       The same as CMAKE_SYSTEM_NAME but for the host system instead of the
       target system when cross compiling.

  CMAKE_HOST_SYSTEM_PROCESSOR
       The name of the CPU CMake is running on.

       The same as CMAKE_SYSTEM_PROCESSOR but for the host system instead of
       the target system when cross compiling.

  CMAKE_HOST_SYSTEM_VERSION
       OS version CMake is running on.

       The same as CMAKE_SYSTEM_VERSION but for the host system instead of
       the target system when cross compiling.

  CMAKE_HOST_UNIX
       True for UNIX and UNIX like operating systems.

       Set to true when the host system is UNIX or UNIX like (i.e.  APPLE and
       CYGWIN).

  CMAKE_HOST_WIN32
       True on windows systems, including win64.

       Set to true when the host system is Windows and on Cygwin.

  CMAKE_LIBRARY_ARCHITECTURE
       Target architecture library directory name, if detected.

       This is the value of CMAKE_<lang>_LIBRARY_ARCHITECTURE as detected for
       one of the enabled languages.

  CMAKE_LIBRARY_ARCHITECTURE_REGEX
       Regex matching possible target architecture library directory names.

       This is used to detect CMAKE_<lang>_LIBRARY_ARCHITECTURE from the
       implicit linker search path by matching the <arch> name.

  CMAKE_OBJECT_PATH_MAX
       Maximum object file full-path length allowed by native build tools.

       CMake computes for every source file an object file name that is
       unique to the source file and deterministic with respect to the full
       path to the source file.  This allows multiple source files in a
       target to share the same name if they lie in different directories
       without rebuilding when one is added or removed.  However, it can
       produce long full paths in a few cases, so CMake shortens the path
       using a hashing scheme when the full path to an object file exceeds a
       limit.  CMake has a built-in limit for each platform that is
       sufficient for common tools, but some native tools may have a lower
       limit.  This variable may be set to specify the limit explicitly.  The
       value must be an integer no less than 128.

  CMAKE_SYSTEM
       Name of system cmake is compiling for.

       This variable is the composite of CMAKE_SYSTEM_NAME and
       CMAKE_SYSTEM_VERSION, like this
       ${CMAKE_SYSTEM_NAME}-${CMAKE_SYSTEM_VERSION}.  If CMAKE_SYSTEM_VERSION
       is not set, then CMAKE_SYSTEM is the same as CMAKE_SYSTEM_NAME.

  CMAKE_SYSTEM_NAME
       Name of the OS CMake is building for.

       This is the name of the operating system on which CMake is targeting.
       On systems that have the uname command, this variable is set to the
       output of uname -s.  Linux, Windows, and Darwin for Mac OS X are the
       values found on the big three operating systems.

  CMAKE_SYSTEM_PROCESSOR
       The name of the CPU CMake is building for.

       On systems that support uname, this variable is set to the output of
       uname -p, on windows it is set to the value of the environment
       variable PROCESSOR_ARCHITECTURE

  CMAKE_SYSTEM_VERSION
       OS version CMake is building for.

       A numeric version string for the system, on systems that support
       uname, this variable is set to the output of uname -r.  On other
       systems this is set to major-minor version numbers.

       True for Cygwin.

       Set to true when using Cygwin.

  ENV
       Access environment variables.

       Use the syntax $ENV{VAR} to read environment variable VAR.  See also
       the set() command to set ENV{VAR}.

       Set to true when the compiler is version 6.0 of Microsoft Visual C.

  MSVC70
       True when using Microsoft Visual C 7.0

       Set to true when the compiler is version 7.0 of Microsoft Visual C.

  MSVC71
       True when using Microsoft Visual C 7.1

       Set to true when the compiler is version 7.1 of Microsoft Visual C.

Variables for Languages

  CMAKE_<LANG>_ARCHIVE_APPEND
       Rule variable to append to a static archive.

       This is a rule variable that tells CMake how to append to a static
       archive.  It is used in place of CMAKE_<LANG>_CREATE_STATIC_LIBRARY on
       some platforms in order to support large object counts.  See also
       CMAKE_<LANG>_ARCHIVE_CREATE and CMAKE_<LANG>_ARCHIVE_FINISH.

       object file for the language <LANG>.

  CMAKE_<LANG>_CREATE_SHARED_LIBRARY
       Rule variable to create a shared library.

       This is a rule variable that tells CMake how to create a shared
       library for the language <LANG>.

  CMAKE_<LANG>_CREATE_SHARED_MODULE
       Rule variable to create a shared module.

       This is a rule variable that tells CMake how to create a shared
       library for the language <LANG>.

  CMAKE_<LANG>_CREATE_STATIC_LIBRARY
       Rule variable to create a static library.

       This is a rule variable that tells CMake how to create a static
       library for the language <LANG>.

  CMAKE_<LANG>_FLAGS
       Flags for all build types.

       <LANG> flags used regardless of the value of CMAKE_BUILD_TYPE.

  CMAKE_<LANG>_FLAGS_DEBUG
       Flags for Debug build type or configuration.

       <LANG> flags used when CMAKE_BUILD_TYPE is Debug.

  CMAKE_<LANG>_FLAGS_MINSIZEREL
       Flags for MinSizeRel build type or configuration.

       <LANG> flags used when CMAKE_BUILD_TYPE is MinSizeRel.Short for
       minimum size release.

  CMAKE_<LANG>_FLAGS_RELEASE
       Flags for Release build type or configuration.

       <LANG> flags used when CMAKE_BUILD_TYPE is Release

  CMAKE_<LANG>_FLAGS_RELWITHDEBINFO
       Flags for RelWithDebInfo type or configuration.

       <LANG> flags used when CMAKE_BUILD_TYPE is RelWithDebInfo.  Short for
       Release With Debug Information.

  CMAKE_<LANG>_IGNORE_EXTENSIONS
       File extensions that should be ignored by the build.

       This is a list of file extensions that may be part of a project for a
       given language but are not compiled.

  CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES
       Directories implicitly searched by the compiler for header files.

       CMake does not explicitly specify these directories on compiler
       command lines for language <LANG>.  This prevents system include
       directories from being treated as user include directories on some
       compilers.

  CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES
       Implicit linker search path detected for language <LANG>.

       Compilers typically pass directories containing language runtime
       libraries and default library search paths when they invoke a linker.
       These paths are implicit linker search directories for the compiler's
       language.  CMake automatically detects these directories for each
       language and reports the results in this variable.

       When a library in one of these directories is given by full path to
       target_link_libraries() CMake will generate the -l<name> form on link
       lines to ensure the linker searches its implicit directories for the
       library.  Note that some toolchains read implicit directories from an
       environment variable such as LIBRARY_PATH so keep its value consistent
       when operating in a given build tree.

  CMAKE_<LANG>_IMPLICIT_LINK_FRAMEWORK_DIRECTORIES
       Implicit linker framework search path detected for language <LANG>.

       These paths are implicit linker framework search directories for the
       compiler's language.  CMake automatically detects these directories
       for each language and reports the results in this variable.

  CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
       Implicit link libraries and flags detected for language <LANG>.

       Compilers typically pass language runtime library names and other
       flags when they invoke a linker.  These flags are implicit link
       options for the compiler's language.  CMake automatically detects
       these libraries and flags for each language and reports the results in
       this variable.

  CMAKE_<LANG>_LIBRARY_ARCHITECTURE
       Target architecture library directory name detected for <lang>.

       If the <lang> compiler passes to the linker an architecture-specific
       system library search directory such as <prefix>/lib/<arch> this
       variable contains the <arch> name if/as detected by CMake.

  CMAKE_<LANG>_LINKER_PREFERENCE
       Preference value for linker language selection.

       The "linker language" for executable, shared library, and module
       targets is the language whose compiler will invoke the linker.  The
       LINKER_LANGUAGE target property sets the language explicitly.
       Otherwise, the linker language is that whose linker preference value
       is highest among languages compiled and linked into the target.  See
       also the CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES variable.

  CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES
       True if CMAKE_<LANG>_LINKER_PREFERENCE propagates across targets.

       This is used when CMake selects a linker language for a target.
       Languages compiled directly into the target are always considered.  A
       language compiled into static libraries linked by the target is
       considered if this variable is true.

  CMAKE_<LANG>_LINK_EXECUTABLE 
       Rule variable to link an executable.

       Rule variable to link an executable for the given language.

  CMAKE_<LANG>_OUTPUT_EXTENSION
       Extension for the output of a compile for a single file.

       This is the extension for an object file for the given <LANG>.  For
       example .obj for C on Windows.

  CMAKE_<LANG>_PLATFORM_ID
       An internal variable subject to change.

       This is used in determining the platform and is subject to change.

  CMAKE_<LANG>_SIZEOF_DATA_PTR
       Size of pointer-to-data types for language <LANG>.

       This holds the size (in bytes) of pointer-to-data types in the target
       platform ABI.  It is defined for languages C and CXX (C++).

  CMAKE_<LANG>_SOURCE_FILE_EXTENSIONS
       Extensions of source files for the given language.

       This is the list of extensions for a given language's source files.

  CMAKE_COMPILER_IS_GNU<LANG>
       True if the compiler is GNU.

       If the selected <LANG> compiler is the GNU compiler then this is TRUE,
       if not it is FALSE.  Unlike the other per-language variables, this
       uses the GNU syntax for identifying languages instead of the CMake
       syntax.  Recognized values of the <LANG> suffix are:

         CC = C compiler
         CXX = C++ compiler
         G77 = Fortran compiler

  CMAKE_Fortran_MODDIR_DEFAULT
       Fortran default module output directory.

       Most Fortran compilers write .mod files to the current working
       directory.  For those that do not, this is set to "." and used when
       the Fortran_MODULE_DIRECTORY target property is not set.

  CMAKE_Fortran_MODDIR_FLAG
       Fortran flag for module output directory.

       This stores the flag needed to pass the value of the
       Fortran_MODULE_DIRECTORY target property to the compiler.

  CMAKE_Fortran_MODOUT_FLAG
       Fortran flag to enable module output.

       Most Fortran compilers write .mod files out by default.  For others,
       this stores the flag needed to enable module output.

  CMAKE_INTERNAL_PLATFORM_ABI
       An internal variable subject to change.

       This is used in determining the compiler ABI and is subject to change.

  CMAKE_USER_MAKE_RULES_OVERRIDE_<LANG>
       Specify a CMake file that overrides platform information for <LANG>.

       This is a language-specific version of CMAKE_USER_MAKE_RULES_OVERRIDE
       loaded only when enabling language <LANG>.

------------------------------------------------------------------------------
Variables that Control the Build

  CMAKE_<CONFIG>_POSTFIX
       Default filename postfix for libraries under configuration <CONFIG>.

       When a non-executable target is created its <CONFIG>_POSTFIX target
       property is initialized with the value of this variable if it is set.

  CMAKE_<LANG>_VISIBILITY_PRESET
       Default value for <LANG>_VISIBILITY_PRESET of targets.

       This variable is used to initialize the <LANG>_VISIBILITY_PRESET
       property on all the targets.  See that target property for additional
       information.

  CMAKE_ARCHIVE_OUTPUT_DIRECTORY
       Where to put all the ARCHIVE targets when built.

       This variable is used to initialize the ARCHIVE_OUTPUT_DIRECTORY
       property on all the targets.  See that target property for additional
       information.

  CMAKE_AUTOMOC
       Whether to handle moc automatically for Qt targets.

       This variable is used to initialize the AUTOMOC property on all the
       targets.  See that target property for additional information.

  CMAKE_AUTOMOC_MOC_OPTIONS
       Additional options for moc when using automoc (see CMAKE_AUTOMOC).

       This variable is used to initialize the AUTOMOC_MOC_OPTIONS property
       on all the targets.  See that target property for additional
       information.

  CMAKE_BUILD_WITH_INSTALL_RPATH
       Use the install path for the RPATH

       Normally CMake uses the build tree for the RPATH when building
       executables etc on systems that use RPATH.  When the software is
       installed the executables etc are relinked by CMake to have the
       install RPATH.  If this variable is set to true then the software is
       always built with the install path for the RPATH and does not need to
       be relinked when installed.

  CMAKE_DEBUG_POSTFIX
       See variable CMAKE_<CONFIG>_POSTFIX.

       This variable is a special case of the more-general
       CMAKE_<CONFIG>_POSTFIX variable for the DEBUG configuration.

  CMAKE_EXE_LINKER_FLAGS
       Linker flags to be used to create executables.

       These flags will be used by the linker when creating an executable.

  CMAKE_EXE_LINKER_FLAGS_<CONFIG>
       Flags to be used when linking an executable.

       Same as CMAKE_C_FLAGS_* but used by the linker when creating
       executables.

  CMAKE_Fortran_FORMAT
       Set to FIXED or FREE to indicate the Fortran source layout.

       This variable is used to initialize the Fortran_FORMAT property on all
       the targets.  See that target property for additional information.

  CMAKE_Fortran_MODULE_DIRECTORY
       Fortran module output directory.

       This variable is used to initialize the Fortran_MODULE_DIRECTORY
       property on all the targets.  See that target property for additional
       information.

  CMAKE_GNUtoMS
       Convert GNU import libraries (.dll.a) to MS format (.lib).

       This variable is used to initialize the GNUtoMS property on targets
       when they are created.  See that target property for additional
       information.

  CMAKE_INCLUDE_CURRENT_DIR
       Automatically add the current source- and build directories to the
       include path.

       If this variable is enabled, CMake automatically adds in each
       directory ${CMAKE_CURRENT_SOURCE_DIR} and ${CMAKE_CURRENT_BINARY_DIR}
       to the include path for this directory.  These additional include
       directories do not propagate down to subdirectories.  This is useful
       mainly for out-of-source builds, where files generated into the build
       tree are included by files located in the source tree.

       By default CMAKE_INCLUDE_CURRENT_DIR is OFF.

  CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE
       Automatically add the current source- and build directories to the
       INTERFACE_INCLUDE_DIRECTORIES.

       If this variable is enabled, CMake automatically adds for each shared
       library target, static library target, module target and executable
       target, ${CMAKE_CURRENT_SOURCE_DIR} and ${CMAKE_CURRENT_BINARY_DIR} to
       the INTERFACE_INCLUDE_DIRECTORIES.By default
       CMAKE_INCLUDE_CURRENT_DIR_IN_INTERFACE is OFF.

  CMAKE_INSTALL_NAME_DIR
       Mac OS X directory name for installed targets.

       CMAKE_INSTALL_NAME_DIR is used to initialize the INSTALL_NAME_DIR
       property on all targets.  See that target property for more
       information.

  CMAKE_INSTALL_RPATH
       The rpath to use for installed targets.

       A semicolon-separated list specifying the rpath to use in installed
       targets (for platforms that support it).  This is used to initialize
       the target property INSTALL_RPATH for all targets.

  CMAKE_INSTALL_RPATH_USE_LINK_PATH
       Add paths to linker search and installed rpath.

       CMAKE_INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true
       will append directories in the linker search path and outside the
       project to the INSTALL_RPATH.  This is used to initialize the target
       property INSTALL_RPATH_USE_LINK_PATH for all targets.

  CMAKE_LIBRARY_OUTPUT_DIRECTORY
       Where to put all the LIBRARY targets when built.

       This variable is used to initialize the LIBRARY_OUTPUT_DIRECTORY
       property on all the targets.  See that target property for additional
       information.

  CMAKE_LIBRARY_PATH_FLAG
       The flag to be used to add a library search path to a compiler.

       The flag will be used to specify a library directory to the compiler.
       On most compilers this is "-L".

  CMAKE_LINK_DEF_FILE_FLAG  
       Linker flag to be used to specify a .def file for dll creation.

       The flag will be used to add a .def file when creating a dll on
       Windows; this is only defined on Windows.

  CMAKE_LINK_DEPENDS_NO_SHARED
       Whether to skip link dependencies on shared library files.

       This variable initializes the LINK_DEPENDS_NO_SHARED property on
       targets when they are created.  See that target property for
       additional information.

  CMAKE_LINK_INTERFACE_LIBRARIES
       Default value for LINK_INTERFACE_LIBRARIES of targets.

       This variable is used to initialize the LINK_INTERFACE_LIBRARIES
       property on all the targets.  See that target property for additional
       information.

  CMAKE_LINK_LIBRARY_FILE_FLAG
       Flag to be used to link a library specified by a path to its file.

       The flag will be used before a library file path is given to the
       linker.  This is needed only on very few platforms.

  CMAKE_LINK_LIBRARY_FLAG
       Flag to be used to link a library into an executable.

       The flag will be used to specify a library to link to an executable.
       On most compilers this is "-l".

  CMAKE_MACOSX_BUNDLE
       Default value for MACOSX_BUNDLE of targets.

       This variable is used to initialize the MACOSX_BUNDLE property on all
       the targets.  See that target property for additional information.

  CMAKE_MODULE_LINKER_FLAGS
       Linker flags to be used to create modules.

       These flags will be used by the linker when creating a module.

  CMAKE_MODULE_LINKER_FLAGS_<CONFIG>
       Flags to be used when linking a module.

       Same as CMAKE_C_FLAGS_* but used by the linker when creating modules.

  CMAKE_NO_BUILTIN_CHRPATH
       Do not use the builtin ELF editor to fix RPATHs on installation.

       When an ELF binary needs to have a different RPATH after installation
       than it does in the build tree, CMake uses a builtin editor to change
       the RPATH in the installed copy.  If this variable is set to true then
       CMake will relink the binary before installation instead of using its
       builtin editor.

  CMAKE_PDB_OUTPUT_DIRECTORY
       Where to put all the MS debug symbol files from linker.

       This variable is used to initialize the PDB_OUTPUT_DIRECTORY property
       on all the targets.  See that target property for additional
       information.

  CMAKE_POSITION_INDEPENDENT_CODE
       Default value for POSITION_INDEPENDENT_CODE of targets.

       This variable is used to initialize the POSITION_INDEPENDENT_CODE
       property on all the targets.  See that target property for additional
       information.

  CMAKE_RUNTIME_OUTPUT_DIRECTORY
       Where to put all the RUNTIME targets when built.

       This variable is used to initialize the RUNTIME_OUTPUT_DIRECTORY
       property on all the targets.  See that target property for additional
       information.

  CMAKE_SHARED_LINKER_FLAGS
       Linker flags to be used to create shared libraries.

       These flags will be used by the linker when creating a shared library.

  CMAKE_SHARED_LINKER_FLAGS_<CONFIG>
       Flags to be used when linking a shared library.

       Same as CMAKE_C_FLAGS_* but used by the linker when creating shared
       libraries.

  CMAKE_SKIP_BUILD_RPATH
       Do not include RPATHs in the build tree.

       Normally CMake uses the build tree for the RPATH when building
       executables etc on systems that use RPATH.  When the software is
       installed the executables etc are relinked by CMake to have the
       install RPATH.  If this variable is set to true then the software is
       always built with no RPATH.

  CMAKE_SKIP_INSTALL_RPATH
       Do not include RPATHs in the install tree.

       Normally CMake uses the build tree for the RPATH when building
       executables etc on systems that use RPATH.  When the software is
       installed the executables etc are relinked by CMake to have the
       install RPATH.  If this variable is set to true then the software is
       always installed without RPATH, even if RPATH is enabled when
       building.  This can be useful for example to allow running tests from
       the build directory with RPATH enabled before the installation step.
       To omit RPATH in both the build and install steps, use
       CMAKE_SKIP_RPATH instead.

  CMAKE_STATIC_LINKER_FLAGS
       Linker flags to be used to create static libraries.

       These flags will be used by the linker when creating a static library.

  CMAKE_STATIC_LINKER_FLAGS_<CONFIG>
       Flags to be used when linking a static library.

       Same as CMAKE_C_FLAGS_* but used by the linker when creating static
       libraries.

  CMAKE_TRY_COMPILE_CONFIGURATION
       Build configuration used for try_compile and try_run projects.

       Projects built by try_compile and try_run are built synchronously
       during the CMake configuration step.  Therefore a specific build
       configuration must be chosen even if the generated build system
       supports multiple configurations.

  CMAKE_USE_RELATIVE_PATHS
       Use relative paths (May not work!).

       If this is set to TRUE, then CMake will use relative paths between the
       source and binary tree.  This option does not work for more
       complicated projects, and relative paths are used when possible.  In
       general, it is not possible to move CMake generated makefiles to a
       different location regardless of the value of this variable.

  CMAKE_VISIBILITY_INLINES_HIDDEN
       Default value for VISIBILITY_INLINES_HIDDEN of targets.

       This variable is used to initialize the VISIBILITY_INLINES_HIDDEN
       property on all the targets.  See that target property for additional
       information.

  CMAKE_WIN32_EXECUTABLE
       Default value for WIN32_EXECUTABLE of targets.

       This variable is used to initialize the WIN32_EXECUTABLE property on
       all the targets.  See that target property for additional information.

  EXECUTABLE_OUTPUT_PATH
       Old executable location variable.

       The target property RUNTIME_OUTPUT_DIRECTORY supercedes this variable
       for a target if it is set.  Executable targets are otherwise placed in
       this directory.

  LIBRARY_OUTPUT_PATH
       Old library location variable.

       The target properties ARCHIVE_OUTPUT_DIRECTORY,
       LIBRARY_OUTPUT_DIRECTORY, and RUNTIME_OUTPUT_DIRECTORY supercede this
       variable for a target if they are set.  Library targets are otherwise
       placed in this directory.

------------------------------------------------------------------------------
Variables that Provide Information

variables defined by cmake, that give information about the project, and
cmake

  CMAKE_AR
       Name of archiving tool for static libraries.

       This specifies the name of the program that creates archive or static
       libraries.

  CMAKE_ARGC
       Number of command line arguments passed to CMake in script mode.

       When run in -P script mode, CMake sets this variable to the number of
       command line arguments.  See also CMAKE_ARGV0, 1, 2 ...

  CMAKE_ARGV0
       Command line argument passed to CMake in script mode.

       When run in -P script mode, CMake sets this variable to the first
       command line argument.  It then also sets CMAKE_ARGV1, CMAKE_ARGV2,
       ...  and so on, up to the number of command line arguments given.  See
       also CMAKE_ARGC.

  CMAKE_BINARY_DIR
       The path to the top level of the build tree.

       This is the full path to the top level of the current CMake build
       tree.  For an in-source build, this would be the same as
       CMAKE_SOURCE_DIR.

  CMAKE_BUILD_TOOL
       Tool used for the actual build process.

       This variable is set to the program that will be needed to build the
       output of CMake.  If the generator selected was Visual Studio 6, the
       CMAKE_BUILD_TOOL will be set to msdev, for Unix Makefiles it will be
       set to make or gmake, and for Visual Studio 7 it set to devenv.  For
       NMake Makefiles the value is nmake.  This can be useful for adding
       special flags and commands based on the final build environment.

  CMAKE_CACHEFILE_DIR
       The directory with the CMakeCache.txt file.

       This is the full path to the directory that has the CMakeCache.txt
       file in it.  This is the same as CMAKE_BINARY_DIR.

  CMAKE_CACHE_MAJOR_VERSION
       Major version of CMake used to create the CMakeCache.txt file

       This stores the major version of CMake used to write a CMake cache
       file.  It is only different when a different version of CMake is run
       on a previously created cache file.

  CMAKE_CACHE_MINOR_VERSION
       Minor version of CMake used to create the CMakeCache.txt file

       This stores the minor version of CMake used to write a CMake cache
       file.  It is only different when a different version of CMake is run
       on a previously created cache file.

  CMAKE_CACHE_PATCH_VERSION
       Patch version of CMake used to create the CMakeCache.txt file

       This stores the patch version of CMake used to write a CMake cache
       file.  It is only different when a different version of CMake is run
       on a previously created cache file.

  CMAKE_CFG_INTDIR
       Build-time reference to per-configuration output subdirectory.

       For native build systems supporting multiple configurations in the
       build tree (such as Visual Studio and Xcode), the value is a reference
       to a build-time variable specifying the name of the per-configuration
       output subdirectory.  On Makefile generators this evaluates to "."
       because there is only one configuration in a build tree.  Example
       values:

         $(IntDir)        = Visual Studio 6
         $(OutDir)        = Visual Studio 7, 8, 9
         $(Configuration) = Visual Studio 10
         $(CONFIGURATION) = Xcode
         .                = Make-based tools

       Since these values are evaluated by the native build system, this
       variable is suitable only for use in command lines that will be
       evaluated at build time.  Example of intended usage:

         add_executable(mytool mytool.c)
         add_custom_command(
           OUTPUT out.txt
           COMMAND ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool
                   ${CMAKE_CURRENT_SOURCE_DIR}/in.txt out.txt
           DEPENDS mytool in.txt
           )
         add_custom_target(drive ALL DEPENDS out.txt)

       Note that CMAKE_CFG_INTDIR is no longer necessary for this purpose but
       has been left for compatibility with existing projects.  Instead
       add_custom_command() recognizes executable target names in its COMMAND
       option, so "${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool"
       can be replaced by just "mytool".

       This variable is read-only.  Setting it is undefined behavior.  In
       multi-configuration build systems the value of this variable is passed
       as the value of preprocessor symbol "CMAKE_INTDIR" to the compilation
       of all source files.

  CMAKE_COMMAND
       The full path to the cmake executable.

       This is the full path to the CMake executable cmake which is useful
       from custom commands that want to use the cmake -E option for portable
       system commands.  (e.g.  /usr/local/bin/cmake

  CMAKE_CROSSCOMPILING
       Is CMake currently cross compiling.

       This variable will be set to true by CMake if CMake is cross
       compiling.  Specifically if the build platform is different from the
       target platform.

  CMAKE_CTEST_COMMAND
       Full path to ctest command installed with cmake.

       This is the full path to the CTest executable ctest which is useful
       from custom commands that want to use the cmake -E option for portable
       system commands.

  CMAKE_CURRENT_BINARY_DIR
       The path to the binary directory currently being processed.

       This the full path to the build directory that is currently being
       processed by cmake.  Each directory added by add_subdirectory will
       create a binary directory in the build tree, and as it is being
       processed this variable will be set.  For in-source builds this is the
       current source directory being processed.

  CMAKE_CURRENT_LIST_DIR
       Full directory of the listfile currently being processed.

       As CMake processes the listfiles in your project this variable will
       always be set to the directory where the listfile which is currently
       being processed (CMAKE_CURRENT_LIST_FILE) is located.  The value has
       dynamic scope.  When CMake starts processing commands in a source file
       it sets this variable to the directory where this file is located.
       When CMake finishes processing commands from the file it restores the
       previous value.  Therefore the value of the variable inside a macro or
       function is the directory of the file invoking the bottom-most entry
       on the call stack, not the directory of the file containing the macro
       or function definition.

       See also CMAKE_CURRENT_LIST_FILE.

  CMAKE_CURRENT_LIST_FILE
       Full path to the listfile currently being processed.

       As CMake processes the listfiles in your project this variable will
       always be set to the one currently being processed.  The value has
       dynamic scope.  When CMake starts processing commands in a source file
       it sets this variable to the location of the file.  When CMake
       finishes processing commands from the file it restores the previous
       value.  Therefore the value of the variable inside a macro or function
       is the file invoking the bottom-most entry on the call stack, not the
       file containing the macro or function definition.

       See also CMAKE_PARENT_LIST_FILE.

  CMAKE_CURRENT_LIST_LINE
       The line number of the current file being processed.

  CMAKE_EXTRA_GENERATOR
       The extra generator used to build the project.

       When using the Eclipse, CodeBlocks or KDevelop generators, CMake
       generates Makefiles (CMAKE_GENERATOR) and additionally project files
       for the respective IDE.  This IDE project file generator is stored in
       CMAKE_EXTRA_GENERATOR (e.g.  "Eclipse CDT4").

  CMAKE_EXTRA_SHARED_LIBRARY_SUFFIXES
       Additional suffixes for shared libraries.

       Extensions for shared libraries other than that specified by
       CMAKE_SHARED_LIBRARY_SUFFIX, if any.  CMake uses this to recognize
       external shared library files during analysis of libraries linked by a
       target.

  CMAKE_GENERATOR

       Native build system toolset name specified by user.

       Some CMake generators support a toolset name to be given to the native
       build system to choose a compiler.  If the user specifies a toolset
       name (e.g.  via the cmake -T option) the value will be available in
       this variable.

  CMAKE_PARENT_LIST_FILE
       Full path to the CMake file that included the current one.

       While processing a CMake file loaded by include() or find_package()
       this variable contains the full path to the file including it.  The
       top of the include stack is always the CMakeLists.txt for the current
       directory.  See also CMAKE_CURRENT_LIST_FILE.

  CMAKE_PATCH_VERSION
       The patch version of cmake (i.e.  the 3 in X.X.3).

       This specifies the patch version of the CMake executable being run.

       This specifies name of the program that randomizes libraries on UNIX,
       not used on Windows, but may be present.

  CMAKE_ROOT
       Install directory for running cmake.

       This is the install root for the running CMake and the Modules
       directory can be found here.  This is commonly used in this format:
       ${CMAKE_ROOT}/Modules

  CMAKE_SCRIPT_MODE_FILE
       Full path to the -P script file currently being processed.

       When run in -P script mode, CMake sets this variable to the full path
       of the script file.  When run to configure a CMakeLists.txt file, this
       variable is not set.

  CMAKE_SIZEOF_VOID_P
       Size of a void pointer.

       This is set to the size of a pointer on the machine, and is determined
       by a try compile.  If a 64 bit size is found, then the library search
       path is modified to look for 64 bit libraries first.

  CMAKE_SKIP_RPATH
       If true, do not add run time path information.

       If this is set to TRUE, then the rpath information is not added to
       compiled executables.  The default is to add rpath information if the
       platform supports it.  This allows for easy running from the build
       tree.  To omit RPATH in the install step, but not the build step, use
       CMAKE_SKIP_INSTALL_RPATH instead.

  CMAKE_SOURCE_DIR
       The path to the top level of the source tree.

       This is the full path to the top level of the current CMake source

  CMAKE_TWEAK_VERSION
       The tweak version of cmake (i.e.  the 1 in X.X.X.1).

       This specifies the tweak version of the CMake executable being run.
       Releases use tweak < 20000000 and development versions use the date
       format CCYYMMDD for the tweak level.

  CMAKE_VERBOSE_MAKEFILE
       Create verbose makefiles if on.

       This variable defaults to false.  You can set this variable to true to
       make CMake produce verbose makefiles that show each command line as it
       is used.

  CMAKE_VERSION
       The full version of cmake in major.minor.patch[.tweak[-id]] format.

       This specifies the full version of the CMake executable being run.

       component appears in non-release versions and may be arbitrary text.

  CMAKE_VS_PLATFORM_TOOLSET
       Visual Studio Platform Toolset name.

       VS 10 and above use MSBuild under the hood and support multiple
       compiler toolchains.  CMake may specify a toolset explicitly, such as
       "v110" for VS 11 or "Windows7.1SDK" for 64-bit support in VS 10
       Express.  CMake provides the name of the chosen toolset in this
       variable.

  CMAKE_XCODE_PLATFORM_TOOLSET
       Xcode compiler selection.

       Xcode supports selection of a compiler from one of the installed
       toolsets.  CMake provides the name of the chosen toolset in this
       variable, if any is explicitly selected (e.g.  via the cmake -T
       option).

  PROJECT_BINARY_DIR
       Full path to build directory for project.

       This is the binary directory of the most recent PROJECT command.

  PROJECT_NAME
       Name of the project given to the project command.

       Top level source directory for the current project.

       This is the source directory of the most recent PROJECT command.

  [Project name]_BINARY_DIR
       Top level binary directory for the named project.

       A variable is created with the name used in the PROJECT command, and
       is the binary directory for the project.  This can be useful when
       SUBDIR is used to connect several projects.

  [Project name]_SOURCE_DIR
       Top level source directory for the named project.

       A variable is created with the name used in the PROJECT command, and
       is the source directory for the project.  This can be useful when
       add_subdirectory is used to connect several projects.
