What about having configure fail by default if an incomplete installation of
Qt5 is found even if Qt4 might work? I'm thinking this might avoid some
confusion. The error message might say something like
ERROR: An incomplete set of Qt5 libraries and tools appears to be
installed on your system. You may fix your Qt5 installation or try the
configure option --with-qt=4 if you would prefer to use Qt4 libraries and
tools.
We would only fall back to Qt4 automatically if none of the required Qt5
libraries and tools are detected.
Yeah, I think that would be better. So if and only if there are no Qt 5
pkg-config files present, then automatically try with Qt 4.
