Description Treeve Jelbert 2016-12-23 11:49:42 UTC 
qtbase-5.8.0 does not install libQt5PlatformSupport, so kwin fails to find it and cmake fails.

libQt5PlatformSupport is part of the private API. Do you also have the 
private dev packages installed?

How did you install Qt?

Support for qt 5.8 was added to trunk in this commit, would be nice to have it backported to Plasma/5.8 (it's not clear whether qt 5.8 will be released before Plasma 5.9)

we cannot. Technically speaking that would break the dependency freeze. 
If distros want to combine Plasma 5.8 with Qt 5.8 they need to 
cherry-pick the commit.

KWin is not compatible with Qt 5.8 anyway.
Comment 6 Christoph Feck 2017-03-18 17:08:26 UTC 
Odd. Using KWin with Qt 5.8 here.
