CMP0071
-------

.. versionadded:: 3.10

Let :prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC` process
:prop_sf:`GENERATED` files.

Since version 3.10, CMake processes **regular** and :prop_sf:`GENERATED`
source files in :prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC`.
In earlier CMake versions, only **regular** source files were processed.
:prop_sf:`GENERATED` source files were ignored silently.

This policy affects how source files that are :prop_sf:`GENERATED`
get treated in :prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC`.

The ``OLD`` behavior for this policy is to ignore :prop_sf:`GENERATED`
source files in :prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC`.

The ``NEW`` behavior for this policy is to process :prop_sf:`GENERATED`
source files in :prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC` just like regular
source files.

.. note::

  To silence the ``CMP0071`` warning source files can be excluded from
  :prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC` processing by setting the
  source file properties :prop_sf:`SKIP_AUTOMOC`, :prop_sf:`SKIP_AUTOUIC` or
  :prop_sf:`SKIP_AUTOGEN`.

Source skip example::

  # ...
  set_property(SOURCE /path/to/file1.h PROPERTY SKIP_AUTOMOC ON)
  set_property(SOURCE /path/to/file2.h PROPERTY SKIP_AUTOUIC ON)
  set_property(SOURCE /path/to/file3.h PROPERTY SKIP_AUTOGEN ON)
  # ...
