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.
