Upstream is archived
I don't know whether it's of any interest but since upstream got archived and I had PRs to it, I made a release on my fork. The most important addition is support for theming KDE apps.
The following additional deps are required to make a full-feature build:
- qtdeclarative
- kconfig
- kcolorscheme
- kiconthemes
And qqc2-desktop-style as a runtime-only dependency (it has to be a required one as long as the package is built with qtdeclarative as Qt crashes when it's unable to find the requested QtQuick style).

It's also available as an AUR package: https://aur.archlinux.org/packages/qt6ct-kde
