# AUTOGEN_TARGET_DEPENDS

Additional target dependencies of the corresponding <ORIGIN>_autogen target.

> Note

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

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_TARGET_DEPENDS` target property can be set to a semicolon-separated list of additional dependencies for the <ORIGIN>_autogen target. Dependencies can be target names or file names.

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.

## Use cases

If `AUTOMOC` or `AUTOUIC` depends on a file that is either

- a `GENERATED` non C++ file (e.g. a `GENERATED` `.json` or `.ui` file) or

- a `GENERATED` C++ file that isn't recognized by `AUTOMOC` and `AUTOUIC` because it's skipped by `SKIP_AUTOMOC`, `SKIP_AUTOUIC`, `SKIP_AUTOGEN` or `CMP0071` or

- a file that isn't in the origin target's sources

it must be added to `AUTOGEN_TARGET_DEPENDS`.
