The "compiler" is a separate package that needs to be installed. One called g++ can be installed on it's own and is also included within a bundle of packages called "build-essential".

Thus sudo apt-get install build-essential solves the problem (and sudo apt-get install g++ should also work), allowing cmake .. to work with no configuration necessary.
