# - try to find tag algorithm library (built on TooN)
#
# Users may optionally supply:
#  TAG_ROOT_DIR - a prefix to start searching for the toon headers.
#
# Cache Variables: (probably not for direct use in your scripts)
#  TAG_INCLUDE_DIR
#  TAG_LIBRARY
#
# Non-cache variables you might use in your CMakeLists.txt:
#  TOONTAG_FOUND
#  TOONTAG_INCLUDE_DIRS
#  TOONTAG_LIBRARIES
#
# Requires these CMake modules:
#  FindPackageHandleStandardArgs (known included with CMake >=2.6.2)
