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.
