After commenting out some lines depending on JUCE, all works fine.

// src/Main.cpp

#include "add1.h"
// #include "audio.h"
#include <iostream>
int main(int argc, char** argv) {
    std::cout << "Hello World" << std::endl;
    std::cout << "1 + 1 = " << add1(1) << std::endl;
    // initializeJuce();
    // playTestSound();
    return 0;
}

// Builds/WASM/Makefile
// Line #12

SOURCES = \
  $(SRC)/Main.cpp \
	$(SRC)/add1.cpp \
	# $(SRC)/audio.cpp

You can check the result with yarn serve
