+INTERFACE_AUTOMOC_MACRO_NAMES
+-----------------------------
+
+.. versionadded:: 3.27
+
+A :ref:`semicolon-separated list <CMake Language Lists>` of macro names for
+:prop_tgt:`AUTOMOC` to be propagated to consumers.
+
+When a target with :prop_tgt:`AUTOMOC` enabled links to a library that sets
+``INTERFACE_AUTOMOC_MACRO_NAMES``, the target inherits the listed macro names
+and merges them with those specified in its own :prop_tgt:`AUTOMOC_MACRO_NAMES`
+property. The target will then automatically generate MOC files for source
+files that contain the inherited macro names too, not just the macro names
+specified in its own :prop_tgt:`AUTOMOC_MACRO_NAMES` property.
+
+By default ``INTERFACE_AUTOMOC_MACRO_NAMES`` is empty.
+
+See the :manual:`cmake-qt(7)` manual for more information on using CMake
+with Qt.
+
+Example 1
+^^^^^^^^^
+
+In this example, ``myapp`` inherits the macro names ``STATIC_LIB_1`` and
+``STATIC_LIB_2`` from ``static_lib``. The ``moc`` tool will then automatically
+be run on any of the ``myapp`` sources which contain ``STATIC_LIB_1`` or
+``STATIC_LIB_2``.
+
+.. code-block:: cmake
+
+ set(AUTOMOC ON)
+ add_executable(myapp main.cpp)
+ target_link_libraries(myapp PRIVATE static_lib)
+
+ add_library(static_lib STATIC static.cpp)
+ set_property(TARGET static_lib PROPERTY
+ INTERFACE_AUTOMOC_MACRO_NAMES "STATIC_LIB_1;STATIC_LIB_2"
+ )
+
+Example 2
+^^^^^^^^^
+
+In this example, the ``INTERFACE_AUTOMOC_MACRO_NAMES`` target property of the
+various ``*_deep_lib`` libraries will propagate to ``shared_lib``,
+``static_lib`` and ``interface_lib``. Because the linking relationships are
+specified as ``PUBLIC`` and ``INTERFACE``, those macro names will also further
+propagate transitively up to ``app``.
+
+.. code-block:: cmake
+
+ set(AUTOMOC ON)
+
+ add_library(shared_deep_lib SHARED deep_lib.cpp)
+ add_library(static_deep_lib STATIC deep_lib.cpp)
+ add_library(interface_deep_lib INTERFACE)
+
+ set_property(TARGET shared_deep_lib PROPERTY
+ INTERFACE_AUTOMOC_MACRO_NAMES "SHARED_LINK_LIB"
+ )
+ set_property(TARGET static_deep_lib PROPERTY
+ INTERFACE_AUTOMOC_MACRO_NAMES "STATIC_LINK_LIB"
+ )
+ set_property(TARGET interface_deep_lib PROPERTY
+ INTERFACE_AUTOMOC_MACRO_NAMES "INTERFACE_LINK_LIB"
+ )
+
+ add_library(shared_lib SHARED lib.cpp)
+ add_library(static_lib STATIC lib.cpp)
+ add_library(interface_lib INTERFACE)
+
+ # PUBLIC and INTERFACE here ensure the macro names propagate to any
+ # consumers of shared_lib, static_lib or interface_lib too
+ target_link_libraries(shared_lib PUBLIC shared_deep_lib)
+ target_link_libraries(static_lib PUBLIC static_deep_lib)
+ target_link_libraries(interface_lib INTERFACE interface_deep_lib)
+
+ # This consumer will receive all three of the above custom macro names as
+ # transitive usage requirements
+ add_executable(app main.cpp)
+ target_link_libraries(app PRIVATE shared_lib static_lib interface_lib)
+
+In the above:
+
+* ``shared_lib`` sources will be processed by ``moc`` if they contain
+ ``SHARED_LINK_LIB``.
+* ``static_lib`` sources will be processed by ``moc`` if they contain
+ ``STATIC_LINK_LIB``.
+* ``app`` sources will be processed by ``moc`` if they contain
+ ``SHARED_LINK_LIB``, ``STATIC_LINK_LIB`` or ``INTERFACE_LINK_LIB``.
