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
#]=======================================================================]
