How to use openmp in xcode?

Question

C++ / C#

I am learning the openmp library. I am using the Xcode environment. Wrote the first simple program

#include <iostream>
#include <omp.h>

int main() {
#pragma omp parallel
    std::cout << "hello, world" << std::endl;

    return 0;
}

An error occurred while compiling: "omp.h" file not found. After reading the Internet, I found out that it seems like the default Apple LLVM compiler does not support working with openmp.
Tried running the program from terminal using g++

$ g++-6 -fopenmp main.cpp
$ ./a.out
hello, worldhello, worldhello, worldhello, world




$

As you can see everything works.
I wanted to change the compiler in XCode, but there is nothing in the list except for Apple LLVM

Question: how can I use the openmp library in XCode?
