When using the GLAD web service, I am allowed to pick any version of OpenGL and any extensions I want.If I pick the latest version of OpenGL and all extensions, will the header file returned by the Web Service #define extensions on my machine that I do not actually have or does it just define those that exist?In other words, if I include the GL_ARB_SHADER_CLOCK extension, on GLAD, does it get defined even if not available on the machine I use?I don't see how it could be selectively defining extensions because the script is generated on a server ahead of time but I want to make sure that I am not trying to use unsupported extensions.
How do I include all extensions my system supports using GLAD
