Well, it's not complicated. We run a cmake configure_command and build_command on the downloaded sip code:

        CONFIGURE_COMMAND ${PYTHON_EXECUTABLE_PATH} <SOURCE_DIR>/configure.py -b ${PREFIX_ext_sip}/bin -d ${PREFIX_ext_sip}/lib/python3.8/site-packages -e ${PREFIX_ext_sip}/include  --sipdir ${PREFIX_ext_sip}/sip --target-py-version 3.8 --sip-module PyQt5.sip
        BUILD_COMMAND make

For PyQt it's the same:

        CONFIGURE_COMMAND ${PYTHON_EXECUTABLE_PATH} <SOURCE_DIR>/configure.py ${_PYQT_conf}
        BUILD_COMMAND make

We cannot use any prebuilt binaries because we need to use our own build of Qt.
