CMP0118

New in version 3.20.

The 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. It may be set by cmake_policy() or cmake_minimum_required(). If it is not set, CMake does not warn with regard to visibility of the GENERATED property, but does warn about setting the GENERATED property to a non-boolean value,, and uses OLD behavior.

Note

The OLD behavior of a policy is deprecated by definition and may be removed in a future version of CMake.
