Installation:
-------------
1. Extract source archive:
   tar xzf ${PROJECT_NAME}-v${VERSION}-src.tar.gz
   cd ${PROJECT_NAME}-v${VERSION}

2. Build from source (WSL):
   wsl bash -c "make build-all"

3. Or use pre-built binaries:
   tar xzf ${PROJECT_NAME}-v${VERSION}-${OS}-${ARCH}.tar.gz
   .\bin\eh_engine_ultimate_bench
