There are no Makefiles. 

It all works through the magic of the R package system. Witmess:

Those two commands would be identical for you on Windows (provided you
installed wget and of course the Rtools needed to compile R packages).

We have a vignette Rcpp-package that has more on how to use Rcpp et al in
your package.  You can of course also just copy RcppExamples and start from
there.  And/or use Rcpp.package.skeleton().

Hope this helps,  Dirk
