The method I posted is the most correct in my opinion. Should work with any framework, etc.
As far as I know, all of the documentation regarding frameworks in the toolchain are Apple docs (you can google around to see what you can find), since the Xcode toolchain is used for Mac compiling and linking. qmake just provides a way for the developer to pass options to the compile and link steps, but those are not Qt options, they're options for the compiler/linker, etc.
