# - try to find TooN headers
#
# Users may optionally supply:
#  TOON_ROOT_DIR - a prefix to start searching for the toon headers.
#
# Cache Variables: (probably not for direct use in your scripts)
#  TOON_INCLUDE_DIR
#
# Non-cache variables you might use in your CMakeLists.txt:
#  TOON_FOUND
#  TOON_INCLUDE_DIRS
#  TOON_LIBRARIES
#
# Requires these CMake modules:
#  FindPackageHandleStandardArgs (known included with CMake >=2.6.2)
