Ok, so you know how to build a configure script. Good for you.

But this is wrong and exactly as I guessed.

Please study the R documentation about src/Makevars, the Rcpp documentation
(there is an entire vignette about how to write a package with a Rcpp, and a
corresponding chapter in my book) and/or any of the 200+ CRAN packages using
Rcpp. 

It looks like you did something by hand, and you did it wrong.  As you are
not showing us what you did we cannot help.

Just build an empty package via Rcpp.package.skeleton() and compare how it
installs.  You'll get this fixed in no time.
