Yes, you do need 'R CMD INSTALL someSourceArchive-1.2-3.tar.gz' because that
is how R works. 

How to add your own dependencies is explained in Writing R Extensions as well
as in our Rcpp-package vignette.

Lastly, the CRAN package for Rcpp lists 20 other packages uses it. Some use
GSL, some use Boost, ... so you could look around there and see how others
have solved the issue.
