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.
