That line can be removed I think.

CMake should already know the path for the include. It should be part of 
Qt5Core_INCLUDE_DIRECTORIES, and when I do a make VERBOSE=1, I 
get -I/home/stephen/dev/prefix/qtbase/mkspecs/linux-g++-64 in the output.

Have you done a clean qtbase build in the last few weeks?
