    location is selected, and files are copied over.

    How? It currently searches for modules across both locations using
    the :class:`.utils.PythonModuleFinder`. then with the help
    of :func:`_package_data_contain_module`, it identifies which
    one are either already included or missing from the distribution.

    Once a module has been identified as ``missing``, it is both copied
    into the :func:`.constants.CMAKE_INSTALL_DIR()` and added to the
