Visual Studio Compiler with UnrealEngine

Hi everyone !
I don’t want do use visual studio to write c++ code, but I know that unreal engine doesn’t support other IDE… and I know that unreal only use the compiler of visual studio, I that I can use other IDE if I have VS installed…
I figured out that I can download only the compiler of VS if I want it. That’s what I’ve done, but unreal doesn’t recognize it and still show the error message : No compiler was found …] install visual studio.
What can I do to make this work without having to install the 10Gb of VS2015 ?
