CMP0163ΒΆ
Added in version 3.30.
The GENERATED
source file property is now visible in all directories.
In CMake 3.29 and below, the GENERATED
source file property,
like other source file properties, was scoped in every directory separately.
Although 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
get_property()
and 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 GENERATED
source file
property as globally scoped. Once it is set in one directory, it is
immediately visible to get_property()
and
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 CMP0118
: the GENERATED
property may
be set only to boolean values, and may not be turned off once turned on.
This policy was introduced in CMake version 3.30.
It may be set by cmake_policy()
or cmake_minimum_required()
.
If it is not set, CMake does not warn, 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.
