How can I generate UUID in c++, without using boost library?

Question

I want to generate UUID for my application to distinguish each installation of my application. I want to generate this UUID using C++ without boost library support. How can I generate UUID using some other opensource library?

Note: My platform is windows

This will do, if you're using modern C++.

#include <random> #include <sstream>  namespace uuid {     static std::random_device              rd;     static std::mt19937                    gen(rd());     static std::uniform_int_distribution<> dis(0, 15);     static std::uniform_int_distribution<> dis2(8, 11);      std::string generate_uuid_v4() {         std::stringstream ss;         int i;         ss << std::hex;         for (i = 0; i < 8; i++) {             ss << dis(gen);         }         ss << "-";         for (i = 0; i < 4; i++) {             ss << dis(gen);         }         ss << "-4";         for (i = 0; i < 3; i++) {             ss << dis(gen);         }         ss << "-";         ss << dis2(gen);         for (i = 0; i < 3; i++) {             ss << dis(gen);         }         ss << "-";         for (i = 0; i < 12; i++) {             ss << dis(gen);         };         return ss.str();     } }
