You can't control which dynamic libraries are used by setting qt.conf 
variables. You control stuff like plugin location. The dynamic libraries 
are linked to the application by the dynamic linker before the 
application starts up.

The usual way to do this on Unix is to set LD_LIBRARY_PATH before 
calling the executable. For this you need to have a script that is what 
the user starts.

On Windows, you can also do this, but I think you will often find that 
applications copy the necessary libraries to the application bin dir.
