# Find the Agg library.

# The Agg library, if found.

# Result variables
# ^^^^^^^^^^^^^^^^

# This module will set the following variables in your project:
#
# ``AGG_INCLUDE_DIRS``
# where to find agg_basics.h, etc.
# ``AGG_LIBRARIES``
# the libraries to link against to use Agg.
# ``Agg_FOUND``
# If false, do not try to use Agg.
