I am not sure about lapack. Its usefulness may be limited but you
probably want to configure it some other way than looking for
libgfortan, libblas and liblapack in that order.
you probably want to be able to pass linking flags for it through
configure. And replace configure.in by configure.ac. configure.in
is deprecated and support for it may disappear sooner rather than
later.
