You'll need to include that directory somehow.  (And when you figure out 
how, a changeset for configure.ac can be made.

I would guess

-I/sw/lib/qt5-mac/lib/QtCore.framework/Versions/5/Headers

is what's missing from you c++ compiler command.  Does adding

  --includedir=/sw/lib/qt5-mac/lib/QtCore.framework/Versions/5/Headers

to the configure help?  If so, then in the configure.ac file Headers 
needs to be added specifically for Mac OS X systems.
