On some setups the xvfb based unit testing fails with this line at the end of the test outout:
/usr/bin/xvfb-run: line 186: kill: (3923210) - No such process

Ok, on fedora there is a newer xvfb version which includes a new option for a more robust choice of a suitable display number which seems to fix the issue for me.
Unfortunately this option is not available on ubuntu 18.04.. To be a bit more future proof I would suggest to make the actual call to xvfb-run configurable via a CMake option and default this to the current value that works on Ubuntu
