Code 3D Game in C++ using OpenGL and SDL2

Hi, I need a Simple First Person game developed from the sample code given in the link .

You must use the SAMPLE code as a starting point. You must use OpenGL 4 for graphics. You must
use SDL for opening the window and event management.

You may use external art assets if you wish (i.e. ones you didn’t make yourself), but make sure to
reference them. You may use third-party libraries, such as image loaders or object loaders, but
make sure to reference them In a word document for me.

The Game is Simple, First person character shooting an enemy, respawn an enemy after each kill. I would like the enemy to be a simple cylinder for this project.

Here is an example of what I'm looking for; https://www.youtube.com/watch?v=a3MACw5hB2Q
