How to install binary versions for both 5 and 6.

[MorningLightMountain713]

Hi there, I have some systems that are running Ubuntu 18/20 that can only run zeromq@5 but also newer systems on Ubuntu 24 that can only run zeromq@6.

I want to install the pre built binaries for both versions depending on the OS.

The way I have been doing this is specifying them both as optional dependencies and installing both - and letting one fail. However this always ends up in one getting built from source and failing - which can take a long time.

How can I install the prebuilt binaries for both, using the same package.json file?

Ubuntu 18/20 = zeromq@5
Ubuntu 24 = zeromq@6

Thanks
