# Find the Tiff library.
#
# Imported targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the following :prop_tgt:`IMPORTED` target:
#
# ``Tiff::Tiff``
# The Tiff library, if found.
#
# Result variables
# ^^^^^^^^^^^^^^^^
#
# This module will set the following variables in your project:
#
# ``TIFF_INCLUDE_DIRS``
# where to find tiff.h, etc.
# ``TIFF_LIBRARIES``
# the libraries to link against to use Tiff.
# ``Tiff_FOUND``
# If false, do not try to use Tiff.
