Adding a cmakelint target to a CMake project

First install the cmakelint tool like this:

pip install cmakelint

Then add a linting target to your CMake project:

find_program(CMAKELINT_EXECUTABLE NAMES cmakelint cmakelint.py)
if(CMAKELINT_EXECUTABLE)
    file(GLOB_RECURSE ALL_CMAKE_FILES CMakeLists.txt *.cmake)
    add_custom_target(
        cmakelint
        COMMAND ${CMAKELINT_EXECUTABLE} ${ALL_CMAKE_FILES}
        COMMENT "Running cmakelint tool"
        VERBATIM
    )
endif()
