Thanks for the bug report, I think the main problem was a wrong/legacy
dependency qt5declarative --> qt5xmlpatterns, instead of the other
way round and a missing target install of the qml parts of the package
qt5xmlpatterns....should be fixed by [1] (only compile tested, not yet
runtime tested)...

Peter
