OpenSceneGraph/include/osgGLUT/GLUTEventAdapter
Robert Osfield d91b848a63 Checked in migration from osgUtil based GUIAdapter code to Neil Salter's
osgGA (Gui Abstraction).  This may break users code, but all it should
require to fix the builds should be a change from
osgUtil::CameraManipulator (etc) to osgGA::CameraManipulator and
include <osgUtil/CameraManipulator (etc) to osgGA/CameraManipulator and
the extra dependency of the link line.
