This is a general tracker for building LXQt in EPEL8.
We are far from being able to build LXQt in EPEL8.
DEBUG util.py:593: No matching package to install: 'cmake(PolkitQt5-1)'
DEBUG util.py:593: No matching package to install: 'kf5-kwindowsystem-devel'
that stuff is currently available only in epel8-playground, fwiw.
I have plans to make kf5 (and friends) for epel8 too, as time allows.
