# Clone repo and submodules:
git clone --recurse-submodules https://github.com/jude253/CWasmGame.git
# Setup up emscripten
./setup_emscripten.sh
Make a build (doesn't have to be named build/) directory, run cmake with relative path to project root from there, then run make. Somewhat like the unix style build, but with no configure step yet.
mkdir build
cd build
cmake ..
make
The generated output code would then be in the ./build/dist/ directory following the above commands.
I included a simple CMakePresets.json file in the root of this project, but I don't understand how that's supposed to be used yet. It seems to run the cmake command, but not make command in the ./build/ directory, if you save in CMakeLists.txt in vscode with CMake extensions installed. I haven't yet understood the full scope of what that can do and what it's intented for. It seems like it could be a good way to have the compiled WASM update more automatically from saving files or something, but I am not sure how to do that or if that's really the purpose of this file yet.
