Compile ZeroMQ crate for Rust on older ARM target

I'm developing some new components on newer ARM target. However, there is a rather large install base of older devices that are difficult to update due to customer-specific stuff on them. I got stuck with compiling ZeroMQ there and I'm looking for a ghost to do the following while I work on actual application: Cross cross compile [login to view URL] to target armv7-unknown-linux-musleabihf on Ubuntu 22 / Intel (which we use to build the overall system). Deliverables: - Rust code to send or receive any messages (to itself or any zeromq sample code) over ZMQ - Using zmq crate - Running on armv7-unknown-linux-musleabihf - Instructions to do the cross-compile and possible modifications. Note that we've got old glibc version on the old targets, so 0MQ should *not* depend on glibc! To filter our robot offers from Real Programmers: is glibc dynamically or statically linked ?
