| |
| The :prop_sf:`GENERATED` source file property is now visible in all directories. |
| |
| Whether or not a source file is generated is an all-or-nothing global |
| property of the source. Consequently, the associated ``GENERATED`` |
| property is now visible from any directory scope, not only from the scope |
| for which it was set. |
| |
| Additionally, the ``GENERATED`` property may now be set only to boolean |
| values, and may not be turned off once turned on. |
| |
| The ``OLD`` behavior of this policy is to only allow ``GENERATED`` to be |
| visible from the directory scope for which it was set. The ``NEW`` |
| behavior on the other hand allows it to be visible from any scope. |
| |
| This policy was introduced in CMake version 3.20. Use the |
| :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly. |
| Unlike many policies, CMake version |release| does *not* warn |
| when this policy is not set and simply uses ``OLD`` behavior with regard |
| to visibility of the ``GENERATED`` property. However, CMake does warn |
| about setting the ``GENERATED`` property to a non-boolean value. |
