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`.

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")
|
