Xeus-cpp-lite fails while including libraries after updating to emsdk 3.1.73

[anutosh491]

Updating to emsdk 3.1.73 involves changing the required channel (but rest other build instructions remain same I would assume!)

After updating

1. Build prefix (cmake from conda-forge and emscripten_emscripten-wasm32 from emscripten-forge)

I also don't see these logs anymore when I build locally for emsdk 3.1.73 (I see these when building with 3.1.45)

So I am guessing something doesn't work as we expect it to ?

I removed these logs since it is too noisy.

You can always build jupyterlite-xeus setting verbose to true here: https://github.com/jupyterlite/xeus/blob/main/packages/xeus/src/worker.ts#L160

Closing as fixed in #246
