Add missing dependency for Fedora 29+ source build failures
Fix an issue building KDE from source on Fedora 29+ (likely 30 also):
Building kwindowsystem (build system KDE) from frameworks (7/105)
Cloning kwindowsystem
Source update complete for kwindowsystem: 110 files affected.
Preparing build system for kwindowsystem.
Running cmake...
Unable to configure kwindowsystem with CMake!
Unable to configure kwindowsystem with KDE
But with the RPM added this succeeds now.
