Not necessarily. You as R package author are responsible of getting your
sources into a form understood by 'R CMD ... ' and friends.

Quite possibly, but it is hard to say from what you posted.

My general advice is to fetch a few of the 700+ CRAN packages and study those
with a similar layout -- in your case with C++.  There are numerous ones that
wrap to external C++ libraries and file collections.  You should fine one
that fits.

Hope this helps, Dirk
