The following optional dependencies will be automatically detected. * SDL2 * libedit (for the command-line debugger) * ffmpeg If you have Qt 5 and CMake 3, then you can build mGBA with a GUI: QT=on ./mGBA.SlackBuild As an alternative to running mGBA as an application, you might consider running RetroArch with its mGBA core.
