You added the _linker_ arguments to the _header_ flag. That is wrong: -L/-l
belong to PKG_LIBS.
Try in the src/ directory to decompose the steps into
R CMD COMPILE mylib.dll *.cpp
and
R CMD SHLIB mylib.dll
(or some other name for mylib) to see that you can a) compile (does g++ find
headers) and b) link (does g++ find the dll).
