But writing (or borrowing ?) some hardware detection via either configure /
autoconf or cmake. This is no different than other tasks decided at install-time.

Start with 'Writing R Extensions', as always, and work your way up from
there. And if memory serves there are already a few other packages with SIMD
at CRAN so you can also try to take advantage of the search for a 'token'
(here: 'SIMD') at the (unofficial) CRAN mirror at GitHub:
