!(*) 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.
