"""Top level setup.py file. Uses scikit-build.

    This will build the numba_dpex project. There are two ways to run this file.
    First command line argument is `install` and the other is `develop`. The
    argument `install` will build the _dpexrt_runtime target and install all the
    python modules into _skbuild build directory, where `develop` will just
    build the _dpexrt_runtime target and will not copy any python module into
    _skbuild.

    `install` command:
        ~$ python setup.py install

    `develop` command:
        ~$ python setup.py develop

    To uninstall:
        ~$ pip uninstall numba-dpex

    NOTE: This script doesn't support pypa/build, pypa/installer or other
    standards-based tools like pip, yet.

    TODO: Support `pip install`
