Use built-in << overload

#include <glm/gtx/io.hpp>

auto mat = glm::ortho(0.0f, 800.0f, 0.0f, 600.0f, 0.1f, 100.0f);
cout << mat << endl;

Gives


[[    0.002,    0.000,    0.000,   -1.000]
 [    0.000,    0.003,    0.000,   -1.000]
 [    0.000,    0.000,   -0.020,   -1.002]
 [    0.000,    0.000,    0.000,    1.000]]

im getting this error...any idea why? No member named 'call' in 'glm::detail::compute_to_string<std::vector<glm::mat<4, 4, float, glm::packed_highp>>>'

It's confused between std::to_string and glm::to_string.
