createModule
This function creates a private module, to be used by the current package,
addSystemCommand
Initializes a `Step.Run` with argv, which must at least have the path to the

Creates a `Step.Run` with an executable built with `addExecutable`.
addConfigHeader
Using the `values` provided, produces a C header file, possibly based on a
