1CMP0038 2------- 3 4Targets may not link directly to themselves. 5 6CMake 2.8.12 and lower allowed a build target to link to itself directly with 7a :command:`target_link_libraries` call. This is an indicator of a bug in 8user code. 9 10The ``OLD`` behavior for this policy is to ignore targets which list themselves 11in their own link implementation. The ``NEW`` behavior for this policy is to 12report an error if a target attempts to link to itself. 13 14This policy was introduced in CMake version 3.0. CMake version 15|release| warns when the policy is not set and uses ``OLD`` behavior. Use 16the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly. 17 18.. include:: DEPRECATED.txt 19
