for some reason the group is not what the test expects, it may
not fail if the tests are run as root user but I doubt someone
will do that (I do not for one)
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.
