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. It may be set by cmake_policy() or cmake_minimum_required(). If it is not set, CMake does not warn, and uses OLD behavior.

Note

The OLD behavior of a policy is deprecated by definition and may be removed in a future version of CMake.
