# FreeBSD installs its version of libpopt into /usr/local/, but does
# not put that on the default library and header path.
# Solaris doesn't even ship libpopt. We used to add that path if
# building on *bsd*, but bje points out that will break
# cross-compilation, and it's kind of ugly anyhow. Anyhow, you can
# either set CPPFLAGS and LDFLAGS when running configure, or use
# --with-extra-foo.
