AUTOGEN_SOURCE_GROUP
--------------------

.. versionadded:: 3.9

Name of the  :command:`source_group` for :prop_tgt:`AUTOMOC`,
:prop_tgt:`AUTORCC` and :prop_tgt:`AUTOUIC` generated files.

Files generated by :prop_tgt:`AUTOMOC`, :prop_tgt:`AUTORCC` and
:prop_tgt:`AUTOUIC` are not always known at configure time and therefore can't
be passed to :command:`source_group`.
``AUTOGEN_SOURCE_GROUP`` can be used instead to generate or select
a source group for :prop_tgt:`AUTOMOC`, :prop_tgt:`AUTORCC` and
:prop_tgt:`AUTOUIC` generated files.

For :prop_tgt:`AUTOMOC`, :prop_tgt:`AUTORCC` and :prop_tgt:`AUTOUIC` specific
overrides see :prop_gbl:`AUTOMOC_SOURCE_GROUP`, :prop_gbl:`AUTORCC_SOURCE_GROUP`
and :prop_gbl:`AUTOUIC_SOURCE_GROUP` respectively.
