[Qt-interest] Loading Qt Shared from DLL

[Marco Borm]

Hi,

maybe a wrapper plugin which uses SetDllDirectory() or 
SetEnvironmentVariable() to add the qt libraries directory to the search 
order is a way. After this the plugin loads the real plugin dynamically.
Unfortunately this can result in unexpected side affects for other 
plugins or the application itself.
