Bug#714482: Dependencies

[Franz Schrober]

Just in case someone also wants to build the current hg version with wayland support:

# default dependencies
$ apt-get build-dep libsdl2
# new dependencies for wayland support
$ apt-get install libegl1-mesa-dev libxkbcommon-dev libwayland-dev
# install mercurial
$ apt-get install mercurial
# build it
$ hg http://hg.libsdl.org/SDL
$ cd SDL
$ SDL_PATH="$(pwd)/build/.libs/"
$ ./configure
$ make
# run your application

$ LD_LIBRARY_PATH="${SDL_PATH}:${LD_LIBRARY_PATH}" ./test/testdraw2
