# CMP0153

Added 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This command has long been superseded by the `execute_process()` command and has been deprecated since CMake 3.0.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. It may be set by `cmake_policy()` or `cmake_minimum_required()`. If it is not set, CMake warns, 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.
