AUTOGEN_TARGET_DEPENDS
|
|
|
|
|
----------------------
|
|
|
|
|
|
|
|
|
|
Additional target dependencies of the corresponding ``_autogen`` target.
|
|
|
|
|
|
|
|
|
|
Targets which have their :prop_tgt:`AUTOMOC` or :prop_tgt:`AUTOUIC` property
|
|
|
|
|
``ON`` have a corresponding ``_autogen`` target which generates
|
|
|
|
|
``moc`` and ``uic`` files. As this ``_autogen`` target is created at
|
|
|
|
|
generate-time, it is not possible to define dependencies of it using
|
|
|
|
|
e.g. :command:`add_dependencies`. Instead the
|
|
|
|
|
:prop_tgt:`AUTOGEN_TARGET_DEPENDS` target property can be set to a
|
|
|
|
|
:ref:`;-list <CMake Language Lists>` of additional dependencies for the
|
|
|
|
|
``_autogen`` target. Dependencies can be target names or file names.
|
|
|
|
|
|
|
|
|
|
In total the dependencies of the ``_autogen`` target are composed from
|
|
|
|
|
|
|
|
|
|
- forwarded origin target dependencies
|
|
|
|
|
(enabled by default via :prop_tgt:`AUTOGEN_ORIGIN_DEPENDS`)
|
|
|
|
|
- additional user defined dependencies from :prop_tgt:`AUTOGEN_TARGET_DEPENDS`
|
|

Use cases
|
|
|
|
|
^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
If :prop_tgt:`AUTOMOC` or :prop_tgt:`AUTOUIC` depends on a file that is either
|
|
|
|
|
|
|
|
|
|
- a :prop_sf:`GENERATED` non C++ file (e.g. a :prop_sf:`GENERATED` ``.json``
|
|
|
|
|
or ``.ui`` file) or
|
|
|
|
|
- a :prop_sf:`GENERATED` C++ file that isn't recognized by :prop_tgt:`AUTOMOC`
|
|
|
|
|
and :prop_tgt:`AUTOUIC` because it's skipped by :prop_sf:`SKIP_AUTOMOC`,
|
|
|
|
|
:prop_sf:`SKIP_AUTOUIC`, :prop_sf:`SKIP_AUTOGEN` or :policy:`CMP0071` or
|
|
|
|
|
- a file that isn't in the origin target's sources
|
|
|
|
|
|
|
|
|
|
it must added to :prop_tgt:`AUTOGEN_TARGET_DEPENDS`.
