feat: support build options via npmrc

[aminya]

This makes it possible to specify the build options of zeromq through npmrc.

They are documented here: https://github.com/zeromq/zeromq.js/tree/opts#draft-support

I'm not too familiar with building native node modules but this gives a reference for how to target multiple architectures at once.

I think I saw a reference for specifying universal builds for macOS in Cmake via CMAKE_OSX_ARCHITECTURES=arm64;x86_64, but I'm not sure if node-gyp supports an analogous setting.

We probably don't need that for prebuilds, but if someone desires that now it's possible via the arch option in .npmrc

Yes, how does this interact with pnpm and yarn supportedArchitectures if they list multiple configs? Will this use the parent project's settings? Or will it clobber it with the current platform's architecture?

That's a feature that we don't support yet, and we might look into it. It's quite complicated, and unless a package provides it, I am not sure if it is worth it. https://github.com/evanw/esbuild/blob/fc37c2fa9de2ad77476a6d4a8f1516196b90187e/lib/npm/node-platform.ts#L113

I don’t know what you mean “unless a package provides it”.

The way esbuild supports being installed on multiple architectures is based on splitting the prebuilds across several packages. It would be complicated even if they didn’t support multiple architectures.

I believe the way pnpm and yarn support this is by calling the npm rebuild hooks for each architecture. Basically doing what sharp suggests doing manually:

npm install --cpu=x64 --os=darwin sharp
npm install --cpu=arm64 --os=darwin sharp

We're using Node's native way, which is the arch and target_arch variables.

The code for handling what Esbuild does. There's a lot of management to be done if we want to support that.
