I somehow workaround it. On the RaspberryPi I created a bash script in /usr/bin: /usr/bin/x5 #!/bin/bash xhost +local: sudo /home/pi/adas0002 --platform xcb I made it executable and then on my Desktop-Pc in Qt-Creator I have "/usr/bin/x5" in "Alternate executable on device". Now my application starts with root even without invoking any terminal. I know this is very bad in security point of view but I dont care on my little offline Raspi...

Thanks a lot. :) @raven-worx @giupigna. Problem solved.

"It is possible to get that kind of information from the application executable?" - it's easy. Call ldd PATH_TO_EXECUTABLE in a terminal

AFAIC Qt Creator assumes that examples are self contained. These are a bit of a special case
