Outdated cmake version requirement in glog_install.sh

[c1oud1ess]

I encountered an issue while running the setup.sh script. The glog_install.sh script directly downloads glog from the GitHub repository. However, it seems that the recent updates to the glog codebase have introduced a cmake version requirement that exceeds the cmake version available in Ditto's runtime environment. Therefore, I would like to suggest considering an alternative approach by switching the download source in glog_install.sh to an older version of glog.
