| |
| The :prop_sf:`GENERATED` source file property is now visible in all directories. |
| |
| In CMake 3.29 and below, the :prop_sf:`GENERATED` source file property, |
| like other source file properties, was scoped in every directory separately. |
| Although policy :policy:`CMP0118` allowed sources marked ``GENERATED`` in one |
| directory to be used in other directories without manually marking them as |
| ``GENERATED`` again, the ``GENERATED`` property was still not visible to |
| :command:`get_property` and :command:`get_source_file_property` calls. |
| |
| Whether or not a source file is generated is an all-or-nothing global |
| property of the source: a source is either generated or it is not. |
| CMake 3.30 and above prefer to treat the :prop_sf:`GENERATED` source file |
| property as globally scoped. Once it is set in one directory, it is |
| immediately visible to :command:`get_property` and |
| :command:`get_source_file_property` calls in other directories. |
| This policy provides compatibility for projects that have not been |
| updated for this behavior. |
| |
| The ``OLD`` behavior of this policy is for the ``GENERATED`` source file |
| property to be visible only in the directories in which it is set. The |
| ``NEW`` behavior of this policy is to allow the ``GENERATED`` source file |
| property to be visible in all directories once set in any directory. |
| Furthermore, the ``NEW`` behavior of this policy implies the ``NEW`` |
| behavior of policy :policy:`CMP0118`: the ``GENERATED`` property may |
| be set only to boolean values, and may not be turned off once turned on. |
