GUI does not start under linux on branch 'itk'
The issue
OpenPass was build with -D WITH_GUI=ON
. The branch 'itk' was choosen because the build should include the newest features of the GUI under development. After applying changes on the branch 'itk' as requested in merge request https://gitlab.eclipse.org/eclipse/simopenpass/simopenpass/-/merge_requests/16, the build finished sucessfully under both Windows and Linux. However, the GUI does not work under Linux: When the executable of the openPass GUI isstarted, it seems to launch but no graphical interface pops up. In the task manager, the openPass GUI seems to be running.
