    # a pipe, it strips it away from the output, alternatively you can set the
    # GCC_COLORS= (empty) env variable to temporarily disable colors. The
    # inverse, i.e. preserving colors when Ninja outputs to a pipe can be done
    # with CLICOLOR_FORCE=1: https://github.com/ninja-build/ninja/issues/2196
