CMP0108

New in version 3.18.


A target is not allowed to link to itself even through an ALIAS target.

In CMake 3.17 and below, a target can link to a target aliased to itself.

The OLD behavior for this policy is to allow a target to link to a target aliased to itself.

The NEW behavior of this policy is to prevent a target to link to itself through an ALIAS target.

This policy was introduced in CMake version 3.17. Use the cmake_policy() command to set it to OLD or NEW explicitly. Unlike many policies, CMake version 3.21.0-rc3 does not warn when this 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.
