Having trouble with cmake on Mac. Don't know much about UNIX. I previously typed in git init to eliminate some other errors. Not sure if that was a mistake Here is output from Terminal.

Instead of downloading the .zip file from github, clone the repository by using

git clone https://github.com/kpeeters/cadabra2

The zip file does not contain all the info which the build process needs.

Thanks for letting me know, I will add this to the OS X instructions.
