wmayer 08e239e9f7 CMake: improve handling of shiboken/PySide 
* fix syntax error with message()
* if shiboken/PySide cannot be found print a warning instead of fatal error. Especially for Qt6 builds a self-compiled shiboken6/PySide6 is required that isn't necessarily installed into the system directories so that the (system) Python interpreter may fail to find them
