# FindTIFF
|
|
# --------
|
|
#
|
|
# Find the TIFF library (libtiff).
|
|
#
|
|
# Imported targets
|
|
# ^^^^^^^^^^^^^^^^
|
|
#
|
|
# This module defines the following :prop_tgt:`IMPORTED` targets:
|
|
#
|
|
# ``TIFF::TIFF``
|
|
# The TIFF library, if found.
|
|
#
|
|
# Result variables
|
|
# ^^^^^^^^^^^^^^^^
|
|
#
|
|
# This module will set the following variables in your project:
|
|
#
|
|
# ``TIFF_FOUND``
|
|
# true if the TIFF headers and libraries were found
|
|
# ``TIFF_INCLUDE_DIR``
|
|
# the directory containing the TIFF headers
|
|
# ``TIFF_INCLUDE_DIRS``
|
|
# the directory containing the TIFF headers
|
|
# ``TIFF_LIBRARIES``
|
|
# TIFF libraries to be linked
|
|
#
|
|
# Cache variables
|
|
# ^^^^^^^^^^^^^^^
|
|
#
|
|
# The following cache variables may also be set:
|
|
#
|
|
# ``TIFF_INCLUDE_DIR``
|
|
# the directory containing the TIFF headers
|
|
# ``TIFF_LIBRARY``
|
|
# the path to the TIFF library
|
