[CMake] CMake fixup_bundle for ubuntu 16.04

Wed Dec 13 14:31:09 EST 2017

Dear Konstantin,

Thanks for the email, yes you are right, I was looking this tool time ago, but the fixup_bundle is just a part of the bigger problem, meaning if I want to create a DEB  package with CMake/CPack, how I could tell CPACK to use linuxdeployqt, in runtime.

CMake/CPack in windows and mac osx are doing their job, but in linux no, in linux we need to many additional tools to create a package.

Cheers,

Waldo.

If you did it because your Qt installation is there, that's wrong. The fixup_bundle function should have copied the necessary Qt libs in the install bin folder, so you just need to add that folder to the path.
