Strange... The zsh is my personal favourite, too, but I can't observe
the behaviour you report. In order to narrow down this issue, may you

- give CMake 2.8.5 a try, although it is probably not a CMake quirk,
- use another shell, e.g. bash, to rule out a zsh misconfiguration,
- use apostrophe quoting to tell the shell to keep its hands off?
