Sebastian Holtermann dca5df16c5 Autogen: Process GENERATED files. Add CMP0071.
This lets AUTOMOC and AUTOUIC process GENERATED files which
used to be ignored before.
A new policy CMP0071 ensures that the old behavior of ignoring
GENERATED files is enabled when the CMake compatibility version
CMAKE_MINIMUM_REQUIRED is < 3.10.

CMP0071
-------
Let :prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC` process
:prop_sf:`GENERATED` files.
CMake 3.10 and newer process regular *and* :prop_sf:`GENERATED` source files
in :prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC`.
In CMake 3.9 and lower, only regular source files were processed in
:prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC`,
:prop_sf:`GENERATED` source files were ignored.
This policy affects how :prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC` process
source files that are :prop_sf:`GENERATED`.
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 exclude source files from :prop_tgt:`AUTOMOC` and :prop_tgt:`AUTOUIC`
processing, the boolean source file properties
:prop_sf:`SKIP_AUTOMOC`, :prop_sf:`SKIP_AUTOUIC` and :prop_sf:`SKIP_AUTOGEN`
can be set accordingly.
This policy was introduced in CMake version 3.10. CMake version
|release| warns when the policy is not set and uses ``OLD`` behavior.
Use the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW``
explicitly.
