I get stuck trying to build PyQt5

[Lucas jeffrey]

Im trying to build PyQt5 from source code, but i dont know where to find the source code of PyQt5 neither how to build PyQt5 or how the build process even works. I already built qt5-opensource-src-5.15.14 from source code, and also qwt qscintilla and qtkeychain, but im stuck with PyQt5. Can someone explain me how to do it please?

Hi, simply installing it using
pip install PyQt5
is not an option?

Unfortunately i need to build PyQt5 from source code because i was instructed to do it in that way at work.
After a couple days trying i was able to build PyQt5 but in order for PyQt5 to compile i needed to do some patches in the code (Which i think is not so good), i downloaded the source code from here: https://src.fedoraproject.org/repo/pkgs/mingw-python-qt5/PyQt5-5.15.10.tar.gz/
which seems to be an unofficial download link. Also im missing the dependency PyQt5.sip, i don't understand why it built without that dependency
