[CMake] CMake fixup_bundle for ubuntu 16.04

[Miklos Espak]

Hi,

you need to add the directory where the Qt libs have been installed (along
with your application binaries) to the LD_LIBRARY_PATH. In your case it is
'/home/waldo/Developer/install/Release/bratumia/bin/', as I see.

Also, you do *not* need to add the Qt plugin directories to the library
path. The plugins are loaded at run-time. So that they can be found, you
need to install a qt.conf file in the bin directory with the following
contents:

[Paths]
Prefix=.

You also do *not* need to add "/usr/lib" and "/usr/lib/x86-..." to the
library path. These libraries are searched for by default. 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.

Also, make sure that the DIRS variable contains all the directories where
there are libraries to install, including dependencies.

I hope that helps.

Best regards,
Miklos
