configure.ac is looking for the "QtGui" pkg-config. On my system with
qt4 and 5 installed:

$ pkg-config --modversion QtGui
4.8.6
$ pkg-config --modversion Qt5Gui
5.3.2

We probably need to add --enable-qt4 and --enable-qt5 options to allow
selecting a specific version.

I suggest first testing if cairo works with Qt5 by changing QtGui in
configure.ac to Qt5Gui.
