Details:

The GUI does not compile with Qt5 currently. There are several issues ranging
from include file compatibility to detecting the helper utilities and CPPFLAGS
and LIBS correctly in configure.ac.

I got as far as hacking the results of configure to look at the right paths,
but the changes in header files between Qt4 and Qt5 is blocking me from
getting any further. The recommendations I've seen for compatibility are to
not include the Qt module in #include statements, so for example use


#include <QApplication>


instead of


#include <QtGui/QApplication>


We have quite a few of the latter variety of includes, especially in the
libqterminal directory.
