-------------------------------------

* Link features, as used with the :genex:`LINK_LIBRARY` generator expression,
  gained the ability to have properties that describe their behavior by
  specifying the :variable:`CMAKE_LINK_LIBRARY_<FEATURE>_PROPERTIES` or
  :variable:`CMAKE_<LANG>_LINK_LIBRARY_<FEATURE>_PROPERTIES` variables.
