# I tried to make a cmake toolchain file for this / use cmake but this is far easier.
# NOTE: We are pretending to be emscripten to box2d so it takes WASM code paths, but we don't actually use emscripten.
# WARN: wasm is probably not supported by your default C compiler and linker, overwrite the CC and LD environment variables accordingly.
# Example for MacOS:
# CC = $(shell brew --prefix llvm)/bin/clang
# LD = $(shell brew --prefix llvm)/bin/wasm-ld
