well, an example. I need the full path "/usr/local/lib64/" 
and all I know is the name of the lib, ie. "virtodbc". Now QLibrary can 
find the lib AFAIK using the dynmic linker:

QLibrary lib( "virtodbc" );

now the lib can be used. Thus, the path to the lib file has to be 
available somewhere. However, the documentation of QLibrary states that 
fileName will only return "" without the dir path.
