Thanks for the fast response!
Yup, definitely something wrong with the way CMake is trying to find Qt6Widget, and it’s pointing to several places in CMake where ‘something’ needs to be put, but it’s not saying what, or why, or how.
I did a custom build from the Qt website to my Linux Mint (Cinnamon) system, build-essential and libgl1 (mesa-dev) dependencies are present. (Apt- was up-to-date.)
CMake keeps generating these same error messages and I don’t know what they mean. It’s marking the Widgets “not found” but I don’t know what that means, or what needs to be done to make them ‘found’.
Cheers
