I’m getting Link errors for almost everything related to Qt, even though Qt seemed to build fine (from git open source, branch 6.7.0…)
I have Qt set to 6 and Qt stuff enabled in the CMake Gui, and it finds all the modules … but fails to link. It’s very strange why would it fail to find anything??

Meh never mind. I rebuilt qt 663 instead of 670 and now everthing is ok…
Cosmic Rays perhaps.
