Cannot build on release v0.27.0 and master

[thedevbirb]

As title says I'm trying to build the project using the guide in the readme, but it fails both on the release v0.27.0 and on master at the latest commit 5db3e19.

Some general info:

• OS/CPU: MacOS Sonoma 14.5, M3 Pro CPU
• cmake version: 3.29.2
• rustc/cargo version: 1.78.0

This is the output I'm getting from running cargo xtask build:

On v0.27.0,

Error: "cargo build failed"

Is there something else I need to setup on my part in order to build properly? Thanks for the help!

You need to use rust 1.75 and the wasm-unknown-unknown target should be installed

Thanks for the reply, it works! What do you think of adding this small rust-toolchain.toml file

[toolchain]
channel = "1.75.0"
target = ["wasm32-unknown-unknown"]

and a small section in the README to make sure the wasm32-unknown-unknown target is installed via rustup? I'd happily make a PR for it if you want.

@thedevbirb #1932 should do this. Thanks for the report again.
