AUTOMOC_MACRO_NAMES
-------------------
.. versionadded:: 3.10
A :ref:`semicolon-separated 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.
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`.
See the :manual:`cmake-qt(7)` manual for more information on using CMake
with Qt.
Example
^^^^^^^
In this case the ``Q_OBJECT`` macro is hidden inside another macro
called ``CUSTOM_MACRO``. To let CMake know that source files that contain
``CUSTOM_MACRO`` need to be ``moc`` processed, we call::
set_property(TARGET tgt APPEND PROPERTY AUTOMOC_MACRO_NAMES "CUSTOM_MACRO")
