> KDevelop4 never had trouble finding Qt headerfiles, neither with KDE4 nor with KF5 projects. As far as I can tell KDevelop5 also manages with KDE4 projects, but for every KF5 project I load I need to add a custom header search path via the settings: /opt/local/include/qt5 .

Hi René,
-isystem is implemented, -iframework isn't.

This is resolved by the MakeFileResolver in

I suggest to start by introducing new entries on the test and then fixing them.
