Yes, if I will do something more (and real) I will need some configure
for sure. But still, if it is possible to set flags for linking (-L
and -Wl,-rpath), for me it makes sense that some straightforward way
how to set include paths (-I) and additional compiler options should
exists. In another words, I would expect that Rcpp.plugin.maker will
have not only 'libs' parameter but also 'include.path' and 'flags'

My use case is calling GRASS library functions from R . I didn't
started yet and so far it is not clear what to do. I'm just exploring
the possibilities now. As a developer I don't have GRASS in standard
path and I want to do some ad-hoc tests and for them Rcpp.plugin.maker
is ideal solution. But I think that this approach can be used by
regular (power) users to write some one-purpose R script (with

As you can see, I'm not sure what to do. However, building a package
is highly probable. But I got the impression that some plugin for
inline package have to be the part of a package if I want to enable to
write custom functions which use some library other than standard C++
