in curl:
...
setCurlOption(CURLOPT_HTTPHEADER, tHTTPFormattedHeaderCurlsist);
...

in curlpp:
YourCurlPPEasy.setOpt(curlpp::options::HttpHeader,
listOfHTTPFormattedHeaders);

you can find the relefant interface in the headers in the curlpp
directory. It's fairly straightforward. You should also try to
familiarize yourself with how curl works, since HTTP really can't be
simplified into a simple get- and set-, so you have to think of it as a
configurable sessions (curl handles) instead.
