# ---------------
#
# The module defines the following variables
#
# ``ClangFormat_EXECUTABLE``
# Path to clang-format executable
# ``ClangFormat_FOUND``
# True if the clang-format executable was found.
# ``ClangFormat_VERSION``
# The version of clang-format found
# ``ClangFormat_VERSION_MAJOR``
# The clang-format major version if specified, 0 otherwise
