for compatibilty reasons automoc4 support is not removed but it shall be in the future. automoc4 has not been maintained for a while (last commit is from 2011) and the stable release is from 2009. CMake version >= 2.8.6 provides the functionality for mocking so I see no reason to not make use of it.
