+CMAKE_AUTOMOC_MACRO_NAMES
+----------------------------
+
+Additional macro names used by :variable:`CMAKE_AUTOMOC`
+to determine if a C++ file needs to be processed by ``moc``.
+
+This variable is used to initialize the :prop_tgt:`AUTOMOC_MACRO_NAMES`
+property on all the targets. See that target property for additional
+information.
+
+By default it is empty.
+
+Example
+-------
+Let CMake know that source files that contain ``CUSTOM_MACRO`` must be ``moc``
+processed as well::
+
+ set(CMAKE_AUTOMOC ON)
+ set(CMAKE_AUTOMOC_MACRO_NAMES "CUSTOM_MACRO")
