RcppArmadillo uses whatever R uses. If you tell R to use different BLAS +
LAPACK, then RcppArmadillo will use then.
On Linux that is plug and play if you a) build with dynamic library
configuration and b) use external BLAS/LAPACK. That is the default for Linux
distributions. On Windows you may want to check the 'R Installation and
Administration' manual.
