I added KDE4Attic in the find_package(KF5... call in plasma-
framework/CMakeLists.txt). That yields a "can't find KDE4Attic.

I don't see where and how to add it there, tried a few combinations, but I'm 
very much in the dark how these things work (your explanations help a bit, so 
thanks for that!), and what exactly I need to add, in which order, making it 
quite cumbersome (and so far without success).

I understand that I should change CreateKDELibsDependenciesFile.cmake then, to 
include KDE4_kde4attic? You say the KDE4Attic files must not be exported, I do 
have cmake/KDE4Attic installed along with all the other frameworks, so that's 
wrong then? OTOH, if it's not installed, plasma-framework/CMakeLists.txt will 
not be able to find it. (And if it's installed, it's still not found -- that's 
probably what you're hinting at.)

People *really* need to build also plasma-framework before committing such 
changes to kdelibs[frameworks]. At this point, I'm spending half of my time 
just picking up build breakage from others. I'm having a really hard time 
catching up, plasma-framework hasn't built once, this entire week, and it's 
blocking people from contributing.

Thanks for your help so far,
