CMAKE_AUTOGEN_PARALLEL
----------------------

Number of parallel ``moc`` or ``uic`` processes to start when using
:prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC`.

This variable is used to initialize the :prop_tgt:`AUTOGEN_PARALLEL` property
on all the targets.  See that target property for additional information.

By default :variable:`CMAKE_AUTOGEN_PARALLEL` is unset.
