${this} is a tool for CMake and CTest

Usage:
    ${this} [command] [<options>]
    eg. ${this} debug test -V    # run all test in debug

Options:
    --clang, -c       use Clang compiler (default: CC and CXX)
    --debug, -d       enable debug-mode (default: release-mode)
    --help, -h        print this
    --jobs, -j        set parallel jobs number manually (default: /proc/cpuinfo)
    --test, -t        exec test (next arg: regex-pattern and other options)
