Hi Robert, So just comenting the lines referring to those libraries in the FindOpenCascade.cmake file did the trick. Also tested with a few igs files and all worked ok. So not sure for your opencascade version these libraries are needed to build or/and run, but definitely not needed for me (installed from apt).
Could it be version dependent issues?
