Can't find plugin header (Spine)

I followed every step and it works just fine in the editor.

In the c++ solution it builds OK without adding any Spine functionality.

If I try to add any of it, it does not build.
(e.g. USpineSkeletonComponent or #include “SpineSkeletonComponent.h” or #include “spine/spine.h”)

I added “SpinePlugin” to PublicDependencyModuleNames in

I tried to do this and failed.
PublicIncludePaths.AddRange(new string] { “SpinePlugin/Public”, “SpinePlugin/Classes”});

Why project does not know path to plug in headers?

How can I compile and use it?

UE4 4.22, Spine 3.7, VS2017
