For those looking for a broader/more portable introduction, Xavier Leroy and Didier Rémy wrote a great high-level text on UNIX system programming a long time ago [1]. Of course it uses ocaml (perhaps motivating some to learn that language) but the style is low-level and straightforwardly imperative. The advantage is that it sweeps up a lot of the messy and boring error handling into the ocaml runtime and/or exceptions. This makes the code a lot easier to follow, but of course makes it look misleadingly simpler than it would be in C (etc).
Why would someone want to learn Unix Programming using OCAML? Not a smart choice. Also this does not look easier to read than a shell script either.

Thanks! I just started the OCaml Programming Book this week to learn and language and get better at functional programming.

Static linking libraries for MacOS or Windows is contaminated by GPL/LGPL code, and this is why wxwidgets excludes the disclosure requirement.
Also, if you are looking for a VueJS cross-platform GUI framework for most Desktop and Mobile platforms (modern MacOS hardware and developer account is a requirement):

Qt5/Qt6 frameworks sooner or later cause more problems than they solve, and require a lot more maintenance/support.
Best of luck =3
