go build while building C separately

Question

I have some Go code and some C code (quite a bit really). I am calling the C code from the go code. Here is an example:

test.h

#ifndef TEST_H
#define TEST_H

void test();

#endif

test.c

#include "test.h"

#include <stdio.h>

void test() {
    printf("Hello from C!")
}

main.go

package main

// #include "test.h"
import "C"
import "fmt"

func main() {
    C.test()
}

Imagine I have much more C code. This C code takes a while to compile. When compiling using go build , it recompiles the C every time. Is it possible to compile the C and go separately? Meaning that if I am working on the Golang code, I won't have to compile to C code?

I have tried linking the object files, but it seems very inefficient. If this is the best option? If so, could you provide a code example showing me how (as my way only works on Linux).
