| |
| The loop variables created by :command:`foreach` command have now their scope |
| restricted to the loop scope. |
| |
| Starting with CMake 3.21, the :command:`foreach` command ensures that the loop |
| variables have their scope restricted to the loop scope. |
| |
| The ``OLD`` behavior for this policy let the loop variables to exist, with an |
| empty value, in the outer scope of loop scope. |
| |
| 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. |
