NAME

       cmakevars - Reference of CMake variables.

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.

              This is the line number of the file currently being processed by cmake.

       CMAKE_CURRENT_SOURCE_DIR
              The path to the source directory currently being processed.

              This the full path to the source directory that is  currently  being  processed  by
              cmake.

       CMAKE_DL_LIBS
              Name of library containing dlopen and dlcose.

              The  name  of  the  library that has dlopen and dlclose in it, usually -ldl on most
              UNIX machines.

       CMAKE_EDIT_COMMAND
              Full path to cmake-gui or ccmake.

              This is the full path to the CMake executable that can graphically edit the  cache.
              For example, cmake-gui, ccmake, or cmake -i.

       CMAKE_EXECUTABLE_SUFFIX
              The suffix for executables on this platform.

              The suffix to use for the end of an executable filename if any, .exe on Windows.

              CMAKE_EXECUTABLE_SUFFIX_<LANG> overrides this for language <LANG>.

       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
              The generator used to build the project.

              The name of the generator that is being used to generate the  build  files.   (e.g.
              "Unix Makefiles", "Visual Studio 6", etc.)

       CMAKE_GENERATOR_TOOLSET
              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_HOME_DIRECTORY
              Path to top of source tree.

              This is the path to the top level of the source tree.

       CMAKE_IMPORT_LIBRARY_PREFIX
              The prefix for import libraries that you link to.

              The prefix to use for the name of an import library if used on this platform.

              CMAKE_IMPORT_LIBRARY_PREFIX_<LANG> overrides this for language <LANG>.

       CMAKE_IMPORT_LIBRARY_SUFFIX
              The suffix for import libraries that you link to.

              The  suffix  to  use  for  the  end  of  an import library filename if used on this
              platform.

              CMAKE_IMPORT_LIBRARY_SUFFIX_<LANG> overrides this for language <LANG>.

       CMAKE_LINK_LIBRARY_SUFFIX
              The suffix for libraries that you link to.

              The suffix to use for the end of a library filename, .lib on Windows.

       CMAKE_MAJOR_VERSION
              The Major version of cmake (i.e. the 2 in 2.X.X)

              This specifies the major version of the CMake executable being run.

       CMAKE_MAKE_PROGRAM
              See CMAKE_BUILD_TOOL.

              This variable is around for backwards compatibility, see CMAKE_BUILD_TOOL.

       CMAKE_MINIMUM_REQUIRED_VERSION
              Version specified to cmake_minimum_required command

              Variable containing the VERSION component specified in  the  cmake_minimum_required
              command.

       CMAKE_MINOR_VERSION
              The Minor version of cmake (i.e. the 4 in X.4.X).

              This specifies the minor version of the CMake executable being run.

       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.

       CMAKE_PROJECT_NAME
              The name of the current project.

              This specifies name of the current  project  from  the  closest  inherited  PROJECT
              command.

       CMAKE_RANLIB
              Name of randomizing tool for static libraries.

              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_SHARED_LIBRARY_PREFIX
              The prefix for shared libraries that you link to.

              The prefix to use for the name of a shared library, lib on UNIX.

              CMAKE_SHARED_LIBRARY_PREFIX_<LANG> overrides this for language <LANG>.

       CMAKE_SHARED_LIBRARY_SUFFIX
              The suffix for shared libraries that you link to.

              The suffix to use for the end of a shared library filename, .dll on Windows.

              CMAKE_SHARED_LIBRARY_SUFFIX_<LANG> overrides this for language <LANG>.

       CMAKE_SHARED_MODULE_PREFIX
              The prefix for loadable modules that you link to.

              The prefix to use for the name of a loadable module on this platform.

              CMAKE_SHARED_MODULE_PREFIX_<LANG> overrides this for language <LANG>.

       CMAKE_SHARED_MODULE_SUFFIX
              The suffix for shared libraries that you link to.

              The suffix to use for the end of a loadable module filename on this platform

              CMAKE_SHARED_MODULE_SUFFIX_<LANG> overrides this for language <LANG>.

       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 tree. For an
              in-source build, this would be the same as CMAKE_BINARY_DIR.

       CMAKE_STANDARD_LIBRARIES
              Libraries linked into every executable and shared library.

              This is the list of libraries that are linked into all executables and libraries.

       CMAKE_STATIC_LIBRARY_PREFIX
              The prefix for static libraries that you link to.

              The prefix to use for the name of a static library, lib on UNIX.

              CMAKE_STATIC_LIBRARY_PREFIX_<LANG> overrides this for language <LANG>.

       CMAKE_STATIC_LIBRARY_SUFFIX
              The suffix for static libraries that you link to.

              The suffix to use for the end of a static library filename, .lib on Windows.

              CMAKE_STATIC_LIBRARY_SUFFIX_<LANG> overrides this for language <LANG>.

       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.  This variable
              is defined by  versions  2.6.3  and  higher.   See  variables  CMAKE_MAJOR_VERSION,
              CMAKE_MINOR_VERSION,  CMAKE_PATCH_VERSION,  and  CMAKE_TWEAK_VERSION for individual
              version components.  The [-id] 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.

              This is the name given to the most recent PROJECT command.

       PROJECT_SOURCE_DIR
              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.

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.

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.

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

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.

CYGWIN True for Cygwin.

Set to true when using Cygwin.

MSVC_IDE
True when using the Microsoft Visual C IDE

Set to true when the target platform is the Microsoft Visual C IDE, as opposed to
the command line compiler.

MSVC_VERSION
The version of Microsoft Visual C/C++ being used if any.

Known version numbers are:

1200 = VS 6.0
1300 = VS 7.0
1310 = VS 7.1
1400 = VS 8.0
1500 = VS 9.0
1600 = VS 10.0
1700 = VS 11.0
1800 = VS 12.0

UNIX True for UNIX and UNIX like operating systems.

Set to true when the target system is UNIX or UNIX like (i.e. APPLE and CYGWIN).

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.

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.

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.

       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>.
