Also @kosetin FYI there is a pull request in the works for CMake #7524; it need more testing you can report to https://forum.openframeworks.cc/t/all-about-cmake/41777/18

Beyond that there is not much value in keeping this open — welcome to open another issue with actionable information and relevant title.
