Sorry, where are my manners? The file I had attached had much more than 
was necessary to demonstrate the problem. Here, this is a trivial one:

#include <iostream>
#include <ggl/ggl.hpp>
#include <ggl/geometries/cartesian2d.hpp>
#include <ggl/multi/geometries/multi_polygon.hpp>

int main()
{
     ggl::multi_polygon<ggl::polygon_2d> mp1, mp2;
     std::cout << "mp1 equals mp2?"
               << (ggl::equals(mp1, mp2) ? "YES" : "NO")
               << std::endl;
     return 0;
}
