New in version 3.21.
When this policy is set to NEW
, the scope of loop variables defined by the
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
cmake_policy()
command to set it to OLD
or NEW
explicitly.
Unlike many policies, CMake version 3.21.7 does not warn when the policy
is not set and simply uses OLD
behavior.
Note
The OLD
behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
