For Mac debugging I usually configure Qt 5 like this:

./configure --developer-build -nomake tests -nomake examples -debug -no-framework

You will get only the debug versions of the libraries, so there won't be any trouble pointing Creator to use them.  I'm sure it's not the ideal way, but it works for me, so that Creator can step through Qt code in any module.  But webkit won't build with these settings.
