Linking to preinstalled nlopt binaries

[smartalecH]

I'm on a system where I can't use the normal package manager to install packages.

But luckily, on this system, I've already got the shared .so libraries for nlopt installed. Is there a way I could simply tell Nlopt.jl to look "here" for these libraries and call them that way?

In particular, Overrides.toml seems like the easiest approach. It looks like you can just add a line:

# Override for NLopt_jll
079eb43efd8e547899662cf3e3edb778 = "/foo/bar"

to ~/.julia/artifacts/Overrides.toml, where /foo/bar/lib/libnlopt.so is the location of your libnlopt?

Closing because the Overrides.toml is the way to go about this. This is also documented to a lesser extent in the offial Pkg documentation: https://pkgdocs.julialang.org/v1/artifacts/#Overriding-artifact-locations
