This helps simplify the creation of new apps using the KDE 5 runtime. I'm not sure how to make this also handle KDE 6 simultaneously (but I'm open to suggestions!), but that's more manageable because so few applications currently use Qt 6. (The idea being that if not otherwise changed by then, that this would be switched to use kde6 runtime/common when KDE itself switches to Qt 6.)
I haven't tested this broadly yet, but so far it seems to be doing what I want, and shouldn't break non-KDE usage.
