For building packages with attributes dependencies are specified using
Depends and LinkingTo rather than the Rcpp::depends attribute (this is
covered in the attributes vignette but it certainly could be missed).

Note also that we have an outstanding work item to have
Rcpp.package.skeleton look for Rcpp::depends attribute in cpp_file and
automatically add depended on packages to the DESCRIPTION. For now
though this has to be done manually.
