FindTIFF
--------

Find the TIFF library (``libtiff``, https://libtiff.gitlab.io/libtiff/).

Optional COMPONENTS
^^^^^^^^^^^^^^^^^^^

This module supports the optional component `CXX`, for use with the COMPONENTS
argument of the :command:`find_package` command. This component has an associated
imported target, as described below.

Imported targets
^^^^^^^^^^^^^^^^

This module defines the following :prop_tgt:`IMPORTED` targets:

``TIFF::TIFF``
  The TIFF library, if found.

``TIFF::CXX``
  The C++ wrapper libtiffxx, if requested by the `COMPONENTS CXX` option,
  if the compiler is not MSVC (which includes the C++ wrapper in libtiff),
  and 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_RELEASE``
  the path to the TIFF library for release configurations
``TIFF_LIBRARY_DEBUG``
  the path to the TIFF library for debug configurations
``TIFFXX_LIBRARY_RELEASE``
  the path to the TIFFXX library for release configurations
``TIFFXX_LIBRARY_DEBUG``
  the path to the TIFFXX library for debug configurations
