Yeah, I just didn't see any reference to a pre compiled library in the .pro file.
I'm just adding a subdirectory, placing the kernel in it, compiling to a static lib.
Then I'm just linking to the library in the .pro file. Does that sound like the correct procedure?

Then I need to figure out how to put a command in a .pro file so the qmake generated makefile also runs the make in the subdirectory.
