+CMP0033
+-------
+
+The :command:`export_library_dependencies` command should not be called.
+
+This command was added in January 2003 to export ``<tgt>_LIB_DEPENDS``
+internal CMake cache entries to a file for installation with a project.
+This was used at the time to allow transitive link dependencies to
+work for applications outside of the original build tree of a project.
+The functionality has been superseded by the :command:`export` and
+:command:`install(EXPORT)` commands.
