(*) These libraries are included in our own source repository because they are either poorly available or we were forced to make changes. You can therefore NOT use your own version.

(**)  Any current version should work 

Note: On Windows, we supply precompiled binary packages that are built to work with Orxonox. You do not need to install any libraries except for OpenAL and DirectX. See the [wiki:download] page for further instructions.
