Getting emscripten's header files

[שחר לנגבהיים‎]

Hi, I didn't find the best practices regarding including emscripten.h and html5.h in a project. Most of the examples I see just copy the files into the project, but that means that the only way to receive updates is to copy them manually. 
What's the best way to use emscripten's headers? Add it as a git submodule to my project, and add the submodule's include folder into the search path?

Hi,

I use emsdk to manage the versions of the toolchain I use:

https://github.com/emscripten-core/emsdk

when you execute emcc, it will look for what's in emscripten/system/include so you can easily #include <emscripten.h> or <emscripten/html5.h> (look into emscripten/system/include for the full list of headers)
