I did try to fix it by setting "PYQT_SIP_DIR_OVERRIDE" [1] to point to
the correct sip dir (see the veusz package for instance), but CMake
ignored that variable when I set it.

The problem is that Krita in my machine takes 4 to 5 hours to reach
67%, where it fails, to test if it works or not. In the CI, Krita takes
as many minutes to fail at 67% as Blender takes to fully build.

The functionality was also never "enabled" because the build failed
before it could be used.
