Well I don't even know how to get started...
The only thing I found was to download msys, so I can run configure and make.
This creates libsybdb.a, libsybdb.dll.a mad libsybdb.la files.
Is this what I should be doing to start with?
I really have no idea how Qt was compiled; it is the download LGPL version 
4.6.2 from their website.
What exactly should I look for?

That's the issue I think when compiling with Visual Studio, and trying to use 
the .lib with Qt.
