* The `generator` is whatever type of build system you'd like to use. To see a full list of generators on your platform, just run `cmake` (with no arguments). For example:
* On Windows, you might use "Visual Studio 12 2013" to generate a Visual Studio 2013 solution
* On Windows, you might use "Visual Studio 12 2013" to generate a Visual Studio 2013 solution or "Visual Studio 14 2015 Win64" to generate a 64-bit Visual Studio 2015 solution.
* On OS X, you might use "Xcode" to generate an Xcode project
* On a UNIX-y system, simply omit the option to generate a makefile
