Currently, when using Cake Modules, if it first necessary to do something like the following:

.\build.ps1 --bootstrap

To force Cake to first check and download any Modules that are included within the Cake Script, and then you run the build as normal:

.\build.ps1

This is a minor change to the default bootstrapper to make this happen, however, it would be very nice, if possible, that Cake implicitly did this check and download for any modules added to the Cake, so that it is a single execution of Cake.
