We do indeed add inst/include to the compilation for all packages listed in
Rcpp::depends (Attributes.R:371 adds the package name to the list then the
call to .buildClinkCppFlags on line 419 does the work of locating the
actual directory.

A hint as to what might be happening is in your reference to as and wrap
forwarders. Are there as and wrap forwarders that are sitting in another
include file? If you want to automatically inject additional include files
(e.g. for as and wrap) then you definitely need to define an inline plugin.

If we can't get to the bottom of this by discussion perhaps you could send
a link to either your source code or a representative example and I'll take
a closer look.
