Svmwrap nonlopt 400 [do not merge]

I am not sure this is the right way to do; but in case one of the dependencies cannot install; I might still want to be able to install the software; so there is a git branch where we can compile even without the said dependency (ocaml-nlopt).

Sounds fine. The alternative is to make nlopt a depopts (or have the -nlopt version) and use enabled_if dune feature or something of the kind.

I guess an issue here is that the package name is svmwrap

I just issued a temporary tag for CI tests; I'll issue a final one if tests pass

@UnixJunkie what's left to do on this PR?

[UnixJunkie]

I have a no_nlopt branch; let's just use this one and install from sources if users need it.
