This is an indicator of a bug in +user code. + +The ``OLD`` behavior for this policy is to ignore targets which list themselves +in their own link implementation. The ``NEW`` behavior for this policy is to +report an error if a target attempts to link to itself. + +This policy was introduced in CMake version 3.0. CMake version +|release| warns when the policy is not set and uses ``OLD`` behavior. Use +the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly. + +.. include:: DEPRECATED.txt |
