New in version 3.18.
The Documentation module is removed.
The Documentation was added as a support mechanism for the VTK
project and was tuned for that project. Instead of CMake providing this module
with (now old) VTK patterns for cache variables and required packages, the
module is now deprecated by CMake itself.
The OLD behavior of this policy is for Documentation to add
cache variables and find VTK documentation dependent packages. The NEW
behavior is to act as an empty module.
This policy was introduced in CMake version 3.18. CMake version 3.25.2
warns when the policy is not set and uses OLD behavior. Use the
cmake_policy() command to set it to OLD or NEW explicitly.
Note
The OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
