Compile error "undefined reference to 'sqrt'" in Atom editor

This code in C is not compiling on Atom, but CodeBlocks is working normally.

#include <stdio.h>
#include <math.h>

int main(){
    int a, b, hipotenusa, catetos;

    printf("A: ");
    scanf("%d", &a);

    printf("B: ");
    scanf("%d", &b);

    catetos = (a * a) + (b * b);

    hipotenusa = sqrt(catetos);

    printf("Hipotenusa = %d", hipotenusa);

    return 0;
}

Error:
