Build failure with gcc14

Hello, GCC14 turned some warnings into errors: https://gcc.gnu.org/gcc-14/porting_to.html
This makes this software fail to build, log below:
running install
/usr/lib/python3.12/site-packages/setuptools/_distutils/cmd.py:66: SetuptoolsDeprecationWarning: setup.py install is deprecated.
!!

        ********************************************************************************
        Please avoid running ``setup.py`` directly.
        Instead, use pypa/build, pypa/installer or other
        standards-based tools.

        See https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html for details.
