# Find the Pixman library.

# Imported targets

# This module defines the following :prop_tgt:`IMPORTED` target:
#
# ``Pixman::Pixman``
# The Pixman library, if found.
#
# Result variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``PIXMAN_LIBRARIES``
# the libraries to link against to use Pixman.
# ``Pixman_FOUND``
# If false, do not try to use Pixman.
