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
|
|
