# FindFreetype
# ------------
#
# Find the Freetype font renderer library.
#
# Imported targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the following :prop_tgt:`IMPORTED` target:
#
# ``Freetype::Freetype``
# The Freetype library, if found.
#
# Result variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``FREETYPE_INCLUDE_DIRS``
# where to find ft2build.h, etc.
# ``FREETYPE_LIBRARIES``
# the libraries to link against to use Freetype.
# ``Freetype_FOUND``
# If false, do not try to use Freetype.
