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 cmake_policy command to set it to OLD or +NEW explicitly. |
