# CMP0032

The `output_required_files()` command should not be called.

This command was added in June 2001 to expose the then-current CMake implicit dependency scanner. CMake's real implicit dependency scanner has evolved since then but is not exposed through this command. The scanning capabilities of this command are very limited and this functionality is better achieved through dedicated outside tools.

CMake >= 3.0 prefer that this command never be called. The `OLD` behavior for this policy is to allow the command to be called. The `NEW` behavior for this policy is to issue a `FATAL_ERROR` when the command is called.

This policy was introduced in CMake version 3.0. CMake version 3.28.0-rc1 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.
