You are entitled to your opinion, but there are several system utilities that are available by default on many systems, including rsync. rsync has a well known interface, and is available by default on Linux and Mac OS X. The way CMake does things is often kludgy and just feels wrong. I often write scripts in more effective languages and then run from within CMake on Windows, Linux, and Mac OS X. Perl and Python are often a much better way to go than trying to do everything in CMake.
