# This module accepts the following env variable

# OSGPlugins_LIB_DIR - <OpenSceneGraph>/lib/osgPlugins-<X.X.X> , path to search plugins

|

|
# Once done this will define

# OSGPlugins_FOUND - System has the all required components.

# OSGPlugins_LIBRARIES - Link these to use the required osg plugins components.
