| AUTOGEN_ORIGIN_DEPENDS |
| ---------------------- |
| |
| .. versionadded:: 3.14 |
| |
| Switch for forwarding origin target dependencies to 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`, origin target dependencies are forwarded to |
| the :ref:`<ORIGIN>_autogen_timestamp_deps` target instead of |
| :ref:`<ORIGIN>_autogen` |
| |
| |
| 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_ORIGIN_DEPENDS`` |
| target property decides whether the origin target dependencies should be |
| forwarded to the :ref:`<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` 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` target |
| only. This is especially interesting when a |
| :variable:`global autogen target <CMAKE_GLOBAL_AUTOGEN_TARGET>` is enabled. |
| |
| When the :ref:`<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. |
