.. versionadded:: 3.18
It is not allowed to create an ``ALIAS`` target with the same name as an
another target.
In CMake 3.17 and below, an ``ALIAS`` target can overwrite silently an existing
target with the same name.
The ``OLD`` behavior for this policy is to allow target overwrite.
The ``NEW`` behavior of this policy is to prevent target overwriting.
This policy was introduced in CMake version 3.17. Use the
:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
Unlike many policies, CMake version |release| does *not* warn
when this policy is not set and simply uses ``OLD`` behavior.
