# OSG_LIBRARY
# OSG_FOUND, if false, do not try to link to osg
# OSG_INCLUDE_DIRS, where to find the headers
# OSG_INCLUDE_DIR, where to find the source headers
# OSG_GEN_INCLUDE_DIR, where to find the generated headers

# to use this module, set variables to point to the osg build
# directory, and source directory, respectively
# OSGDIR or OSG_SOURCE_DIR: osg source directory, typically OpenSceneGraph
# OSG_DIR or OSG_BUILD_DIR: osg build directory, place in which you've
#    built osg via cmake 

# Header files are presumed to be included like
# #include <osg/PositionAttitudeTransform>
# #include <osgUtil/SceneView>
