# This FindTIFF.cmake has been contributed by us to upstream CMake.
# It is expected to be released with CMake 3.19.
# See https://gitlab.kitware.com/cmake/cmake/-/merge_requests/4934.
# Therefore we shall delete this file from BornAgain in a couple of years
# when our minimum required CMake version has been incremented to 3.19.

#[=======================================================================[.rst:
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
