On MS Windows: same as above, used in conjunction with MSYS2's [CLANG64](https://www.msys2.org/docs/environments/) environment to build native Win executables from the comfort of a familiar Bash shell using familiar tools (GNU Make, cmake, et al.) [Kitty](https://github.com/kovidgoyal/kitty) is a wonderful terminal, I pretty much live inside it when I'm not on Windows. For libraries, I make use of the various popular ones commonly discussed in the community Discord, and appreciate the Nim [cornucopia](https://github.com/status-im?q=&type=all&language=nim&sort=) developed and maintained by Status.
