No more sipconfig

[scrouthtv]

Hello everyone,
I am currently receiving an error message when trying to build python_qt_binding:

CMake Warning at install/python_qt_binding/share/python_qt_binding/cmake/sip_helper.cmake:20 (message):
  SIP binding generator NOT available.
Call Stack (most recent call first):
  src/qt_gui_cpp_sip/CMakeLists.txt:58 (include)

When ignoring this warning, another error is raised:

ERROR setuptools_scm._file_finders.git listing git files failed - pretending there aren't any
Traceback (most recent call last):
  File "install/python_qt_binding/share/python_qt_binding/cmake/sip_configure.py", line 10, in <module>
    import sipconfig
ModuleNotFoundError: No module named 'sipconfig'

Indeed, I am running these sip versions:

sip 6.9.1-2
python-pyqt5-sip 12.16.1-2

The sipconfig module was last shipped with sip 4.19.x, a version that was released almost 9 years ago.

There is PR #94, which does some changes into this direction, however it is stalled and still using the sipconfig module, i.e. not working.

How would I go about building this package with an updated sip version?
