# - try to find VRPN library
#
# Cache Variables:
# VRPN_LIBRARY
# VRPN_SERVER_LIBRARY
# VRPN_INCLUDE_DIR
#
# Non-cache variables you might use in your CMakeLists.txt:
# VRPN_FOUND
# VRPN_SERVER_LIBRARIES - server libraries
# VRPN_LIBRARIES - client libraries
# VRPN_CLIENT_DEFINITIONS - definitions if you only use the client library
# VRPN_DEFINITIONS - Client-only definition if all we found was the client library.
# VRPN_INCLUDE_DIRS
#
# VRPN_ROOT_DIR is searched preferentially for these files
#
# Requires these CMake modules:
# FindPackageHandleStandardArgs (known included with CMake >=2.6.2)
