Flake does not build cli on Darwin

[TomMD]

What version are you using?

master branch.

What did you do?

git clone followed by nix develop.

What did you expect to see?

stellar, the binary, in my path.

What did you see instead?

Errors about libudev0 which is not something os-x would be using.

Suggestion/Context

PR #1534 added a nix flake but it seems to be Linux only despite the conversation suggesting otherwise. It also continues to call a local.sh despite conversation suggesting that would be removed.

The below diff makes the flake.nix work for darwin but needs effort to turn into a PR. Specifically, we need to detect the build target and selectively not include libudev0 and the nativeBuildInputs.

That's a good point.
We need libudev for ledger signing to work (and it is required to build cli on Linux) -- this is coming from hidapi which is a downstream dependency
The flake has only been tested on Linux, sorry!
Please feel free to open PR to fix the flake for Mac.
I'll also try to fix it later this/next week

Fixed in #1665
