# CMP0153

New in version 3.28.

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

This command has long been superseded by the `execute_process()` command and has been deprecated since CMake 3.0.

CMake >= 3.28 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 3.28. CMake version 3.28.0-rc5 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.
