Where's the definition of class GLRender? Simply putting "class  
GLRender;" in the header won't work. That's an incomplete type (just  
as the compiler says), and about the only thing you can use it for is  
to pass around pointers. But if you're trying to call methods of an  
object, the compiler needs the real thing, not just that stub.

(I don't see what this has to do with qmake or static libs; it's  
simply C++.)
