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
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
.. versionadded:: 3.5
|
|
|
|
This module defines the following :prop_tgt:`IMPORTED` targets:
|
|
|
|
``TIFF::TIFF``
|
|
The TIFF library, if found.
|
|
|
|
``TIFF::CXX``
|
|
.. versionadded:: 3.19
|
|
|
|
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
|
|
|
|
.. versionadded:: 3.4
|
|
Debug and Release variants are found separately.
