# Tries to find the clang-tidy and clang-format modules
#
# Usage of this module as follows:
#
# find_package(ClangTools)
#
# Variables used by this module, they can change the default behaviour and need
# to be set before calling find_package:
#
# ClangToolsBin_HOME -
# When set, this path is inspected instead of standard library binary locations
# to find clang-tidy and clang-format
#
# This module defines
# CLANG_TIDY_BIN, The path to the clang tidy binary
# CLANG_TIDY_FOUND, Whether clang tidy was found
# CLANG_FORMAT_BIN, The path to the clang format binary
# CLANG_TIDY_FOUND, Whether clang format was found
