Describe the bug title

After make install/strip:

dimitris@dimitris-lab:~/Work/CaPTk/CaPTk-build/Debug/install$ bin/captk

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

@sarthakpati here you go. I will update with the actual output when it finishes building

[dboun]

@sarthakpati got the whole output. See 'Describe the bug' section

Were you trying to build the Debug version?

Were you trying to build the Debug version?

Yes

Were you trying to build the Debug version?

But this happens in release too

I tried this build on a Linux (Ubuntu 18.04) VM last night and it went off without a hitch. I'm guessing we need to have documentation on which Linux distros we have tested this pipeline on, since it is logistically not possible for us to support all distros out there.
