![]() You can use this section in the same way that you might use the CMakeGUI to view a list of all the CMake variables available to edit. They're passed to CMake at build time, and override whatever values are in the CMakeLists.txt file. CMAKESYSTEMNAME is what Iâd use in CMake code, PLATFORMID is needed in generator expressions. CMake Examples The following show some simple example of how the CMake script code can look like and what each part does. The CMakeâs default name is CMakeLists.txt, this is important. This is set to lib/pythonX.Y/dist-packages (Debian), lib/pythonX.Y/site-packages (non-Debian) or lib/site-packages (Windows).I have a list of vars definedinside a cmake which is called using from main CMakeLists.txt: add_custom_target(gen_aĬOMMAND $ has no value when I am printing it in cmakelists.txt. These settings enable you to set CMake variables and save them in CMakeSettings.json. Excerpt of a moderators reply on official forum. In the case of FindOpenGL.cmake, it will provide variables for the library and include the file path for the OpenGL on the current system. This variable should not be used directly, use CATKIN_PACKAGE_BIN_DESTINATION instead. C compiler to be used for compilation (default: system specific, gcc on Linux) CMAKECXXCOMPILER. Not work as expected since tools like catkin_find will only consider Some common CMake variables CMAKECCOMPILER. Note that setting this variable to anything but lib or libexec will On non-Debian distributions it could be set to libexec. This variable should not be used directly, use CATKIN_PACKAGE_LIB_DESTINATION instead. But its important to clarify here whether you only want to define these env variables in the presets, or if you actually need to use their values to define other fields of the presets (in which case this. Multiple arguments will be joined as a semicolon. Also, you should be able to set defaults in the CMakeLists.txt file instead: check if an environment variable is defined, and if not, set it. placeholder expect zero or more arguments. Signatures of this command that specify a .See the cmake-language (7) variables documentation for the scopes and interaction of normal variables and cache entries. For example: set(Foo'') 1 quoted arg -> value is ''set(Fooa) 1 unquoted arg -> value is 'a'set(Foo'a b c') 1 quoted arg -> value is 'a b c'set(Fooabc) 3 unquoted args -> value is 'a b c'. Typical entries include Debug, Release, RelWithDebInfo and MinSizeRel, but custom build types can also be defined. Visual Studio, Xcode, or Ninja Multi-Config) as a semicolon-separated list. This destination should only be used when installing headers which are not in a subfolder which matches the project name.Ä®lse you should use the destination CATKIN_PACKAGE_INCLUDE_DESTINATION instead. Set a normal, cache, or environment variable to a given value. Multiple value arguments are packedinto a semicolon-separated list and stored in thevariable as a string. Specifies the available build types (configurations) on multi-config generators (e.g. If you are unsure if you should use this destination use CATKIN_PACKAGE_LIBEXEC_DESTINATION instead. If you do not yet have a cache file and you want to see what options there are in a CMakeLists.txt file, you can do (in a different directory since this will write a cache file): cmake -L /path/to/CMakeLists.txt grep MYCMAKEVARIABLE. ![]() This can be useful when SUBDIR is used to connect. This destination should only be used for the core ROS binaries. A variable is created with the name used in the PROJECT command, and is the binary directory for the project. They only contain relative paths and are supposed to be relative to the $. All destination variables are meant to be used with the CMake install() macro as an DESTINATION argument. 12 contributors Feedback In this article Supported CMake and CMakePresets.json versions Enable CMakePresets.
