Evidently the 'addlibs' thing is somehome comparable to the
`ipopt-config --libs` idea, although not yet convenient for use by the
end user.

However what puzzles me here is why I don't see the dependency on LAPACK
and BLAS and libfortran when I type 'ldd /usr/local/lib/libipopt.so'...
if the IPOPT library uses symbols from those other libraries, why aren't
they shown as binary dependencies?
