Bug 457573

Git master kwin/plasma/frameworks using the gentoo/kde overlay live-git ebuilds.  Last successful kwin update was August 1, to 84e5d92f6, but attempting to rebuild it results in the same error as HEAD (currently ed829eb5a), and a revdep-rebuild now detects that existing kwin as missing libraries so I'm afraid to reboot or restart plasma/kwin as there's a big chance I won't be able to get back into plasma.

The build error is at the end of the configure phase, and relates to a missing KF5::GlobalAccelPrivate (despite kglobalaccel being detected and presumably GlobalAccel being fine, and the last kglobalaccel commit being 5683e036e back on Jul 21, well before my successful kwin build on Aug 1, to the same kwin commit 84e5d92f6 that now fails).

So the culprit doesn't seem to be in either kwin or kglobalaccel, despite the below error.  What else could have caused kwin not to see GlobalAccelPrivate?

I'm including the full features summary below:
