This was undocumented behavior. +Modern use of CMake associates custom commands with their output, rather +than their input. + +The ``OLD`` behavior for this policy is to allow the use of +:command:`add_custom_command` SOURCE signatures. The ``NEW`` behavior for this +policy is to issue an error if such a signature is used. + +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 |
