Rather than just assuming that dependencies are installed, it would be nice if the system checked for them. Additionally such a configuration step could detect if the system shipped with 'qmake' or 'qmake-qt4'.
I've updated the build script to check for dependencies. I think qmake-qt4 is necessary as qmake could try to build using qt5 which I haven't added support for yet.
