Harald and I prototyped another solution to build a Qt
 5 and Qt 6 version out of the same repo and employed it on
plasma-integration: https://invent.kde.org/plasma/plasma-integration/-/
merge_requests/91
This has the advantage of having the code for both versions in 
the same place and the Qt5 version being not stuck on some old
 version. Also the translations can be shared automatically since 
they use the same catalog.
There is one case  where Qt uses unversioned targets and one
unversioned ecm variable but cadavidn be easily worked around.
