The hash is likely to change... We should use the proper conan way to do this

You're right about both, but i don't know how to do this with conan. Maybe @AnotherFoxGuy could help us out here?

You should probably remove this comment

I left this in because those are the flags that can be used to debug emscripten. Instead of removing the command, we should check for CMAKE_BUILD_TYPE=Debug and use the aproprate flags instead.

It's good that you were able to get it to work this way. However I don't think this is the right solution. If Emscripten truly doesn't support multithreading then we can try using coroutines instead. For now, this is a good starting point

i was sure you wouldn't be happy with this solution. (Because i'm not too) According to the documentation:
https://emscripten.org/docs/porting/emscripten-runtime-environment.html#browser-main-loop
it seems to be the only way to do this.
I think we could ifdef this?

I think these should go in CompileOptions.cmake

Fixes #114
Also see #114 for build instructions. It's quite complicated :- /
