This does not rely on the "integrated" clang-format, but instead uses a custom target to achieve the goal. Supports file filtering (to ensure that clang-format only affects supported files), automatic dependency by the project (always run before build), multiple targets and a global target.
Options are:
- TARGETS <target> ...: Targets to add clang-format support to.
- DEPENDENCY: Add a dependency to the given targets so that clang-format runs before building.
- REGEX: Filter out files of the given targets, defaults to '\.(h|hpp|c|cpp)'.
- GLOBAL: Add a global CLANG_FORMAT target.
