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.
