[bug#38149] [WIP] gnu: Add qgis.

[Wiktor Żelazny]

From: Wiktor Żelazny <address@hidden>

* gnu/packages/geo.scm (qgis): new variable.
Does not build due to QtXml/QtXmlmod.sip not found.
---
This is my attempt to define some minimal QGIS package. Unfortunately,
the build crashes with
   sip: Unable to find file "QtXml/QtXmlmod.sip"
but:
   $ ls -l 
/gnu/store/8d1ak3bpaaqhw4hnxksan7fnh5ll7i5f-python-pyqt+qscintilla-5.11.3/share/sip/QtXml/QtXmlmod.sip
   -r--r--r-- 5 root root 1937 Jan  1  1970 
/gnu/store/8d1ak3bpaaqhw4hnxksan7fnh5ll7i5f-python-pyqt+qscintilla-5.11.3/share/sip/QtXml/QtXmlmod.sip
I thought that maybe the QtXml/ directory being a symlink
   QtXml -> 
/gnu/store/mfii8qx5x3kbl1gzg8g8qmblqk6fdmvf-python-pyqt-5.11.3/share/sip/QtXml
was the problem, but including python-pyqt (or python-sip, for that
matter) among the inputs did not solve the issue. Explicitly defining
directories as configure flags does not work, either. Any suggestion how
to progress on this? Thanks!
