AUTOGEN_ORIGIN_DEPENDSΒΆ

Added in version 3.14.

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

Note

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

Targets which have their AUTOMOC or AUTOUIC property ON have a corresponding <ORIGIN>_autogen target which generates moc and uic files. As this <ORIGIN>_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 <ORIGIN>_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 <ORIGIN>_autogen target are composed from

  • forwarded origin target dependencies (enabled by default via AUTOGEN_ORIGIN_DEPENDS)

  • additional user defined dependencies from AUTOGEN_TARGET_DEPENDS

See the 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 <ORIGIN>_autogen target only. This is especially interesting when a global autogen target is enabled.

When the <ORIGIN>_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.
