Bug#903347: libnlopt-cxx-dev: missing dependency on libnlopt-cxx0 (= ${binary:Version})

[Adrian Bunk]

Package: libnlopt-cxx-dev
Version: 2.4.2+dfsg-5
Severity: serious

This makes /usr/lib/x86_64-linux-gnu/libnlopt_cxx.so a dangling
symlink, resulting in users silently using the static library instead.
