-Set this to the list of configuration names available for an IMPORTED
-target.  The names correspond to configurations defined in the project

+Configurations provided for an :ref:`imported target <Imported targets>`.
+
+Set this to the list of configuration names available for an imported
+target.  For each configuration named, the imported target's artifacts
+must be specified in other target properties:
+
+* :prop_tgt:`IMPORTED_LOCATION_<CONFIG>`, or
+* :prop_tgt:`IMPORTED_IMPLIB_<CONFIG>` (on DLL platforms), or
+* :prop_tgt:`IMPORTED_OBJECTS_<CONFIG>` (for :ref:`Object Libraries`), or
+* :prop_tgt:`IMPORTED_LIBNAME_<CONFIG>` (for :ref:`Interface Libraries`).
+
+The configuration names correspond to those defined in the project from
+which the target is imported.  If the importing project uses a different
+set of configurations, the names may be mapped using the
+:prop_tgt:`MAP_IMPORTED_CONFIG_<CONFIG>` target property.
+
+The ``IMPORTED_CONFIGURATIONS`` property is ignored for non-imported targets.
