Hi, i'm debugging an issue with qgis & qt/gtk integration, and had the need to change/try more qt styles, so did a quick port for https://sourceforge.net/projects/qt5ct/ and https://github.com/qt/qtstyleplugins - dunno if that's worth import, and if they should be under x11/qt5 or separate as not part of qt.
