 AUTOMOC_MACRO_NAMES
 -------------------
 
-Additional macro names used by :prop_tgt:`AUTOMOC`
-to determine if a C++ file needs to be processed by ``moc``.
+A :ref:`;-list <CMake Language Lists>` list of macro names used by
+:prop_tgt:`AUTOMOC` to determine if a C++ file needs to be processed by ``moc``.
 
 This property is only used if the :prop_tgt:`AUTOMOC` property is ``ON``
 for this target.
 
-CMake searches for the strings ``Q_OBJECT`` and ``Q_GADGET`` to
-determine if a file needs to be processed by ``moc``.
-:prop_tgt:`AUTOMOC_MACRO_NAMES` allows to add additional strings to the
-search list. This is useful for cases where the ``Q_OBJECT`` or ``Q_GADGET``
-macro is hidden inside another macro.
+When running :prop_tgt:`AUTOMOC`, CMake searches for the strings listed in
+:prop_tgt:`AUTOMOC_MACRO_NAMES` in C++ source and header files.
+If any of the strings is found
+
+- as the first non space string on a new line or
+- as the first non space string after a ``{`` on a new line,
+
+then the file will be processed by ``moc``.
 
 By default :prop_tgt:`AUTOMOC_MACRO_NAMES` is initialized from
-:variable:`CMAKE_AUTOMOC_MACRO_NAMES`, which is empty by default.
+:variable:`CMAKE_AUTOMOC_MACRO_NAMES`.
