| |
| When this policy is set to ``NEW``, the scope of loop variables defined by the |
| :command:`foreach` command is restricted to the loop only. They will be unset |
| at the end of the loop. |
| |
| The ``OLD`` behavior for this policy still clears the loop variables at the end |
| of the loop, but does not unset them. This leaves them as defined, but empty. |
| |
| This policy was introduced in CMake version 3.21. Use the |
| :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly. |
| Unlike many policies, CMake version |release| does *not* warn when the policy |
| is not set and simply uses ``OLD`` behavior. |
