cmake
Cross-platform build automation system, that generates recipes for native build systems.
cmake {{path/to/project_directory}}
Generate a build recipe in the current directory with `CMakeLists.txt` from a project directory:
cmake --build {{path/to/build_directory}}
Use a generated recipe in a given directory to build artifacts:
cmake --install {{path/to/build_directory}} --strip
Install the build artifacts into `/usr/local/` and strip debugging symbols:
