[QGIS-Developer] sip-build takes too long to complete

[Stefanos Natsis]

Thanks for the feedback!

Apparently, I had both sip 4.19.25 and sip-tools 6.7.7 installed which was
possibly causing the slowness.
I brought build times back to normal by doing the following:

- remove all sip-tools 6.7.7 related packages
- install the missing sip-dev package
- delete the SIP_BUILD_EXECUTABLE entry in ccmake
- when configuring, QSCI_SIP_DIR was populated instead
- generate
- delete the build/python/ directory
- ninja

Regards,
Stefanos
