Can't build automatically without --qt4

[Baggypants]

In the build script it checks for qmake, which Fedora only maps to qt4, but then it looks for the qt5 libs and the build fails. I can get around this by only building with --qt4 but it would be useful if the build script looked for qmake-qt5 instead.

Sorry for taking 9 months to get round to this. I've updated the build script to check if qmake-qt5 exists. Please let me know if this works for you on Fedora.

Hey, no worries, sometimes we get busy!
