[QGIS-Developer] sip5: Unable to find file "QtXml/QtXmlmod.sip"

[Hernán De Angelis]

Hi everyone

I am building the latest QGIS 3.16 in Linux openSUSE Tumbleweed. I am 
experiencing a problem I never seen before:

sip5: Unable to find file "QtXml/QtXmlmod.sip"

However, I know where in my system this file exists:

/usr/share/sip/PyQt5/QtXml/QtXmlmod.sip

My problem is that I do not understand how to tell ccmake where to find it.

Any hint is appreciated!

Thanks

Hernán
