Thanks for sharing the CMake patches. I will create a branch tp/cmake-fixes and push commits to this branch. It's been a while I didn't look at this cmake file. I just remember it was sooo long to build. I also remember having problems with finding the python site-packages folder with CMake in order to install pytohnocc package. Thomas
