Emscripten as a linker for Zig and C

This shows how to build a nontrivial program using Zig+Emscripten or C+Emscripten. In both cases Emscripten is only used as a linker, that is the frontend is either zig or clang.

"Nontrivial" here means the program uses interesting Emscripten features:

Asyncify
Full GLES3 support
GLFW3 support

Open Source and Videogames - Resources

This git include a list of programs, tools, engines and libraries free and open source intended to make videogames.

NOTE: This gist is a support material for the talk "Open Source and Videogames" given by me, Ramon Santamaria, on October 26th 2021 in Canòdrom, Barcelona. All the materials listed here were explained in detail in a +2 hours talk.
