AUTOGEN_ORIGIN_DEPENDS

.. versionadded:: 3.14

Switch for forwarding origin target dependencies to the corresponding :ref:<ORIGIN>_autogen <<ORIGIN>_autogen> target.

.. note::

If Qt 5.15 or later is used and the generator is either :generator:`Ninja`
or :ref:`Makefile Generators`, origin target dependencies are forwarded to
the :ref:`<ORIGIN>_autogen_timestamp_deps <<ORIGIN>_autogen_timestamp_deps>`
target instead of :ref:`<ORIGIN>_autogen <<ORIGIN>_autogen>`.

Targets which have their :prop_tgt:AUTOMOC or :prop_tgt:AUTOUIC property ON have a corresponding :ref:<ORIGIN>_autogen <<ORIGIN>_autogen> target which generates moc and uic files. As this :ref:<ORIGIN>_autogen <<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_ORIGIN_DEPENDS target property decides whether the origin target dependencies should be forwarded to the :ref:<ORIGIN>_autogen <<ORIGIN>_autogen> target or not.

By default AUTOGEN_ORIGIN_DEPENDS is initialized from :variable:CMAKE_AUTOGEN_ORIGIN_DEPENDS which is ON by default.

In total the dependencies of the :ref:<ORIGIN>_autogen <<ORIGIN>_autogen> target are composed from

forwarded origin target dependencies (enabled by default via AUTOGEN_ORIGIN_DEPENDS)
additional user defined dependencies from :prop_tgt:AUTOGEN_TARGET_DEPENDS

See the :manual:cmake-qt(7) manual for more information on using CMake with Qt.

.. note::

Disabling ``AUTOGEN_ORIGIN_DEPENDS`` is useful to avoid building of
origin target dependencies when building the
:ref:`<ORIGIN>_autogen <<ORIGIN>_autogen>` target only.
This is especially interesting when a
:variable:`global autogen target <CMAKE_GLOBAL_AUTOGEN_TARGET>` is enabled.

When the :ref:`<ORIGIN>_autogen <<ORIGIN>_autogen>` target doesn't require
all the origin target's dependencies, and ``AUTOGEN_ORIGIN_DEPENDS`` is
disabled, it might be necessary to extend :prop_tgt:`AUTOGEN_TARGET_DEPENDS`
to add missing dependencies.
