[thewh1teagle]

Describe the feature

Add option to compile sherpa-rs to wasm with wasm-pack

• Add example with cmake-rs and minimal cmake project rafaelbeckel/test-c-rust-wasm#3
• Can't build on macOS with cmake-rs rustwasm/wasm-pack#1455
• The compiled code has no functions rust-lang/rust-bindgen#2989 (comment)
• Revisiting wasm32-unknown-unknown rust-skia/rust-skia#1078
• Can't build crate as wasm target georust/proj#115 (comment)

I found that you are asking at
https://users.rust-lang.org/t/build-library-with-wasm-and-cmake-rs/123022

FYI: We use
https://github.com/k2-fsa/sherpa-onnx/blob/master/build-wasm-simd-asr.sh#L17
to build sherpa-onnx for wasm, which is using emsdk 3.1.53

If you use a different version of emsdk, you are likely to fail.

Thanks!
I successfully compiled sherpa with emcc however the Rust crate wasm-bindgen that creates the js bindings currently have some issues with emcc ABI. Is there a way to build sherpa with other wasm target? In rust the target that should work called wasm32-unknown-unknown instead of wasm32-unknown-emscripten that has issues.
