This project is a basehook for the game Counter-Strike specifically. For a more global version, use rdbo/GL-BaseHook. It hooks the function wglSwapBuffers and the Window Proc, and implements Dear ImGUI using my memory lib.
First of all, you have to make sure you have Visual Studio installed.
Then, you just need to open the solution on VS and do the changes you want.
I also recommend turning on the option Show All Files on Visual Studio for a better view of the project.
Have fun!
