how to know the find_package name in cmake?

Question

I am had been forced to cmake and I am working with a lot of external APIs like OpenGL,Vulken and GLFW .. etc. I was using Makefiles very happily but then ....

now each time i had to use find_package for these API.I normaly google and Copy past it. But in practical life , How should I know what is name of that package ? like for OpenGL I had to use find_package(OpenGL REQUIRED) . How should I know it OpenGL and not OPENGL or opengl ? is there any convention ?

please help as I am noob and I am so tried with this cmake :(

CMake stock modules are listed in the documentation . For third-party packages consult the list of files installed by it.
