The gitignore file actually ignores the cmake directory. The CMake file now defaults to modern OpenGL on Unix machines. Before this fix CMake would tell you that 2 versions were available, but it is not clear which one is being used. The random.h file now uses correct C++17 default random number generator. Before this fix C++17 would not compile because the definition of std::shuffle no longer exists. The updated code uses a version of std::shuffle that does exist.
This has been tested and solved on Ubuntu 18.04 LTS with GCC 9.x.x and CMake 3.15.2.
