Yes, this is commonly done via a tool (and language) called 'autoconf' by
writing a test file called 'configure.ac' that is then turned into by
'autoconf' in a file called 'configure' which is run.

Writing those is not easy at first.

As an alternative you _can_ write a shell script 'configure' (or even a
script in another language, including R).  All this does require some effort
of thought so you should think this through.

As none of this has any direct relationship with whether Rcpp is used or not,
follow-up posts may be better off on r-package-devel (a great list if you're
not subscribed yet) or other venues.

Regards, Dirk
