since most of the settings are "frozen" now there is little to no
chance that it will be needed. CMake files that reference paths
for installing .upd files are left intact for now.
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.
