So you define function CxxFlags() and LdFlags() in your package just like we
do for Rcpp --- that is indeed just about the only way I could think of.
Glad know you got that working.

PS Also try
-e "QuadFunc:::CxxFlags()")
instead of
-e "library(QuadFunc); QuadFunc:::CxxFlags()")
as the ::: finds unexported symbols, that usually works from unloaded
packages too. And because of LinkingTo: QuadFunc you may not need the
CxxFlags.
