# Find the Fontconfig library.
#
# Imported targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the following :prop_tgt:`IMPORTED` target:
#
# ``Fontconfig::Fontconfig``
# The Fontconfig library, if found.
#
# Result variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``FONTCONFIG_INCLUDE_DIRS``
# where to find fontconfig/fontconfig.h, etc.
# ``FONTCONFIG_LIBRARIES``
# the libraries to link against to use Fontconfig.
# ``Fontconfig_FOUND``
# If false, do not try to use Fontconfig.
