Qt is a cross-platform application framework that is widely used for developing application software with a graphical user interface (GUI) (in which cases Qt is classified as a widget toolkit), and also used for developing non-GUI programs such as command-line tools and consoles for servers.

Install the Qt support libraries and framework. Use an appropriate package:

+alsa-lib,+bzip2,+dbus,+fontconfig,+freetype,+glib,+grep,+libdrm,+libjpeg,+libtiff,+libxml2,+mesa,+openssl,+tar
