Cmake is not installed

[Yeison Rodriguez]

Julia packages require cmake to build. Cmake is not installed on the Debian image.

Only a handful of packages, this is not universally true. Install it manually if you need to use a package that depends on it, it's not a required dependency of the language or package manager.

Thanks @tkelman for the info. I'll go ahead and close this.
