The NEW behavior for this policy is to diagnose +the existence of such whitespace as an error. The setting for this +policy used when checking the library names is that in effect when the +target is created by an add_executable or add_library command. + +This policy was introduced in CMake version 2.6.0. 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. |
