[Qt-interest] use .obj libary with mingw compiler

[Matthias Pospiech]

I am using a Qt in Visual Studio and have a GPIB Libary (Device to 
Computer Commnication Interface from NI). That works well in Visual Studio.
No I am trying to get the same libary work in QtCreator with mingw. 
However I do not see how to load the libary.

The libary comes as
gpib-32.dll
gpib-32.obj

The documentation says:
     GPIB-32.OBJ           -  Win32 Microsoft Visual C++ language 
interface object module

Any possibilty to load that in QtCreator?
