As you might see, there is nothing about Qt, OIS, mpg123, sndfile...Third-Party Libraries and Tools
OpenMW currently uses the following libraries:
OGRE 1.8rc1.x - the main graphic engine
OIS - a cross-platform C++ input handling library
MyGUI 3.2.0 - the in-game windows and menus
Audiere and OpenAL - for sound support
Bullet 2.80 - the physics engine
OpenMw additionally uses the following tools:
CMake - used to manage the build process
Git - used as the source control management system
I guess that maybe some dependency are system specific (by example, uuid) but when digging into the page, we discover common dependencies absent of the first list.
