AUTOGEN_TARGET_DEPENDS
|
|
----------------------
|
|
|
|
Additional target dependencies of the corresponding :ref:`<ORIGIN>_autogen`
|
|
target.
|
|
|
|
.. note::
|
|
|
|
If Qt 5.15 or later is used and the generator is either :generator:`Ninja`
|
|
or :ref:`Makefile Generators`, additional target dependencies are added to
|
|
the :ref:`<ORIGIN>_autogen_timestamp_deps` target instead of the
|
|
:ref:`<ORIGIN>_autogen` target.
|
|
|
|
|
|
Targets which have their :prop_tgt:`AUTOMOC` or :prop_tgt:`AUTOUIC` property
|
|
``ON`` have a corresponding :ref:`<ORIGIN>_autogen` target which generates
|
|
``moc`` and ``uic`` files. As this :ref:`<ORIGIN>_autogen` target is created
|
|
at generate-time, it is not possible to define dependencies of it using e.g.
|
|
:command:`add_dependencies`. Instead the ``AUTOGEN_TARGET_DEPENDS`` target
|
|
property can be set to a :ref:`;-list <CMake Language Lists>` of additional
|
|
dependencies for the :ref:`<ORIGIN>_autogen` target. Dependencies can be target
|
|
names or file names.
|
|
|
|
In total the dependencies of the :ref:`<ORIGIN>_autogen` target are composed
|
|
from
|
|
|
|
- forwarded origin target dependencies
|
|
(enabled by default via :prop_tgt:`AUTOGEN_ORIGIN_DEPENDS`)
|
|
- additional user defined dependencies from ``AUTOGEN_TARGET_DEPENDS``
|
|
|
|
See the :manual:`cmake-qt(7)` manual for more information on using CMake
|
|
with Qt.

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 be added to ``AUTOGEN_TARGET_DEPENDS``.
