[Rcpp-devel] Setting armadillo preprocessor macros in R package

[JJ Allaire]

If you create a file called pkgname_types.hpp and put it in your src
directory it will be added to RcppExports.cpp ahead of RcppArmadillo.h.
e.g. if your package is named foo then create:

src/foo_types.hpp

And put your #define macros there.
