hmm, I see. Well, we’ve discussed this already a few times in the past weeks. :)
And - slowly - I am beginning to see the trickiness of all this…

Only now that the CI system is eventually building successfully even beyond KF5
I can revisit the still needed patching of the QStandardPaths for the OSX/CI
system.

Well, I thought, that the frameworks themselves have a vendor, namely KDE!
System-wide framework-specific configuration could then go into

	/Library/Application Support/KDE/<framework name>

couldn’t it?

Well, I thought the vendor string was there. At least I remember to have seen
code like that in QStandardPaths...

I’ll check and come back to this later.

I know what you mean and I don’t want to create any fuss about all this.

That said I just tried to report what I observed here on my systems and what
common sense told me. I have no clue about the inner workings of KF5 or Qt5,
as you see from what I write, so take all my comments with a grain of salt. :)

Greets,
