how to build

If emsdk is not installed, you need to clone it from here: https://github.com/emscripten-core/emsdk

and install:

C:\Work\Projects\emsdk\emsdk.bat install latest

Then activate the environment:

C:\Work\Projects\emsdk\emsdk.bat activate latest
C:\Work\Projects\emsdk\emsdk_env.bat

Optionally clear cache:

emcc --clear-cache
embuilder build sdl2 sdl2_ttf sdl2_image sdl2_image_jpg sdl2_image_png

Build:

mkdir build
cd build
emcmake cmake -G Ninja ..
cmake --build .

Optionally install:

cmake --install .

Run:

emrun --no_browser --port 8080 public
