At least the QtCore and KF5/KGlobalAccel include paths are not added (or mislocated) The key is again the cmake log.
On a sidenote: your cmake is terribly outdated. It's listed as minimum for kf5, but even that was wrong (see before issue) and I would not bet even your right arm that it's sufficient for all other repos (despite they may lazily list even older versions as minimum ;-) Cheers, Thomas
