# This is a wrapper for code quality tools supported by CMake.
# 
# It adds these benefits over direct use of the tools:
# 
# - It provides a pattern for filenames on which the tools are to be
#   applied. This limits the noise in relevant diagnostic output and
#   cuts build times by skipping files which are not of interest.
# - It allows changing pattern and arguments without forcing a complete
#   rebuild of all sources handled by this compiler (which is always
#   triggered by changes to the CMake variables).
#
# To use this wrapper, set its full path as the program for each check,
# with the actual tool as the first argument, e.g.
#
#   CMAKE_CXX_CLANG_TIDY="/path/to/code-check-wrapper.sh;clang-tidy"
#   CMAKE_CXX_INCLUDE_WHAT_YOU_USE="/path/to/code-check-wrapper.sh;iwyu"
#
# Any other parameter is ignored. So modifying extra parameters can still
# be used to force a full re-run.
