/CMake 3.19


New in version 3.14.

Switch for forwarding origin target dependencies to the corresponding _autogen target.

Targets which have their AUTOMOC or 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. add_dependencies(). Instead the AUTOGEN_ORIGIN_DEPENDS target property decides whether the origin target dependencies should be forwarded to the _autogen target or not.

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

In total the dependencies of the _autogen target are composed from

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


Disabling AUTOGEN_ORIGIN_DEPENDS is useful to avoid building of origin target dependencies when building the _autogen target only. This is especially interesting when a global autogen target is enabled.

When the _autogen target doesn’t require all the origin target’s dependencies, and AUTOGEN_ORIGIN_DEPENDS is disabled, it might be necessary to extend AUTOGEN_TARGET_DEPENDS to add missing dependencies.
