+UseSWIG-modernize-module
+------------------------
+
+* The :module:`UseSWIG` gained a whole refresh and is now more consistent with
+  standard CMake commands to generate libraries and is fully configurable through
+  properties.

-  The variable ``SWIG_MODULE_<name>_REAL_NAME`` will be set to the name

+  Targets created with command ``swig_add_library`` have the same capabilities as targets
+  created with command :command:`add_library`, so can be used with any command accepting a target
+  especially command :command:`target_link_libraries`.
 
-.. command:: swig_link_libraries
+  The arguments are:
 
-  Link libraries to swig module::
+  ``TYPE``
+    ``SHARED``, ``MODULE`` and ``STATIC`` have same semantic as command :command:`add_library`.
+    if ``USE_BUILD_SHARED_LIBS`` is specified, library type will be ``STATIC`` or ``SHARED``
+    based on whether the current value of the variable :variable:`BUILD_SHARED_LIBS` is ``ON``.
+    If none is specified, ``MODULE`` will be used.
 
-    swig_link_libraries(<name> [ libraries ])
+  ``LANGUAGE``
+    Specify the target language.
 
-Source file properties on module files can be set before the invocation
-of the ``swig_add_library`` macro to specify special behavior of SWIG:
+  ``NO_PROXY``
+    Prevent the generation of the wrapper layer (swig ``-noproxy`` option).
+
+  ``OUTPUT_DIR``
+    Specify where to write the language specific files (swig ``-outdir`` option).
+    If not specified, variable ``CMAKE_SWIG_OUTDIR`` will be used. If none is specified,
+    :variable:`CMAKE_CURRENT_BINARY_DIR` is used.
+
+  ``OUTFILE_DIR``
+    Specify an output directory name where the generated source file will be placed
+    (swig -o option). If not specified, variable ``SWIG_OUTFILE_DIR`` will be used.
+    If none is specified, option ``OUTPUT_DIR`` or variable ``CMAKE_SWIG_OUTDIR`` is used.
+
+  ``SOURCES``
+    List of sources for the library. Files with extension ``.i`` will be identified as sources
+    for ``SWIG`` tool. Other files will be handled in the standard way.
+
+Source files properties on module files **must** be set before the invocation
+of the ``swig_add_library`` command to specify special behavior of SWIG and ensure
