The type (PATH) is not strictly necessary, but causes the Qt based cmake-gui to present the directory chooser dialog. The -i option will cause cmake to interactively prompt for such settings. These can than be specified using the -G command line option. a variable called MYVAR to 1, but the user sets it to 2 with a Timestamp (seconds since epoch) of the function call. Method 2: Installing CMake using command-line. "file": "/full/path/to/the/CMake/file.txt", The ... argument could be used to list only selected files or directories. List variables with help available and exit. The top-level directory in which buildsystem files and build output It supports directory hierarchies and applications that depend on multiple libraries. specified by the preset (variables, generator, etc.) Behavior is default in CMake >= 3.0. This is the default format. If variables are defined using -D, this must be Frequently-used CMake variables . Override the installation prefix, CMAKE_INSTALL_PREFIX. display also advanced variables. Ignored. Run cmake --install with no options for quick help. Build instead of the default target. cmake-buildsystem(7), cmake-commands(7), cmake-compile-features(7), cmake-env-variables(7), cmake-generators(7), cmake-language(7), cmake-modules(7), cmake-packages(7), cmake-properties(7), cmake-qt(7), cmake-server(7), cmake-toolchains(7), cmake-variables(7), cpack-generators(7), debhelper(7), notcurses(3). List policies with help available and exit. CMake Command-Line Reference Examples (TL;DR) Generate a Makefile and use it to compile a project in the same directory as the source: cmake && make Generate a Makefile and use it to compile a project in a separate "build" directory (out-of-source build): cmake -H.-B build && make -C build. Each document is separated by a newline ( \n ). Find variables that are declared or set, but not used. Generate a Makefile and use it to compile a project in the same directory as the source: Generate a Makefile and use it to compile a project in a separate "build" directory (out-of-source build). The help is printed to a named ile if given. Make warnings that are meant for the author of the CMakeLists.txt files List commands with help available and exit. It is correct to write the variable and the type on the CMake command line: cmake -DVARIABLE:TYPE=value path/to/llvm/source. See the CMAKE_GENERATOR_TOOLSET variable for details. silently ignored. takes priority over the project’s default value. Do not actually run configure and generate The major version number in integer form. artifacts (e.g. Step 1. The help is printed to a named ile if given. The help is printed to a named ile if given. The source tree must contain a CMakeLists.txt file. No extra arguments will be added if args=None; definitions (Optional, Defaulted to None): A dict that will be converted to a list of CMake command line variable definitions … If multiple files are specified, the must be directory and it must exist. add_link_options(
