To build and install on Linux, BSD, etc. do the following in a terminal:
1.) cd <path-to-game-dir>/build.
2.) cmake ..
3.) <sudo> make install

Note that the install step is necessary in order to ensure the game's resources
are in the correct location relative to the game's executable. By default make
install will install to /usr/local (exectable in /usr/local/bin, resources in
/usr/local/share/<game-name>). If you'd rather install it elsewhere (e.g. your
home dir) replace step 2 with the following:
cmake -DCMAKE_INSTALL_PREFIX=<alternative-path> ..

You can uninstall the game with make uninstall

You will require the following dependencies to build the game:
SDL 1.2
SDL_image
Freetype
OpenGL
libGLEW
libogg
libvorbis

If you would like additional sound options (e.g. JACK support), you will also
require PortAudio v19.

(naturally you'll want to install the -dev versions of all these libraries)
