Using 3rd party header files with Rcpp

Question

Couple of things:

1. "Third party header libraries" as in your subject makes no sense.

2. Third-party headers can work via templated code where headers are all you need, ie there is only an include step and the compiler resolves things.

3. Once you need libraries and actual linking of object code, you may not be able the powerful and useful sourceCpp unless you gave it meta-information via plugins (or env. vars).

4. So in that case, write a package.

Easy and simple things are just that with Rcpp and the new attributes, or the older inline and cxxfunction. More for complex use --- and external libraries is more complex you need to consult the documentation. We added several vignettes to Rcpp for that.
