If all your C++ sources can be compiled with this wrapper but do not
have to be, then let the user do
./configure CXX=mkoctfile 

If all your C++ sources have to be compiled with this wrapper, then I
guess putting
: ${CXX=mkoctfile} 

in configure.ac before AC_PROG_CXX should allow the user an override but
gives a sensible default for your package. 

If you really need to override only the linker, Automake uses the
undocumented $(CXXLD) variable for linking.  (Maybe it would be a good
idea to document it, not sure.) 

Hope that helps. 

Cheers,
Ralf
