Modify and build a Plugin

Hello everybody.

I am doing Stereo Panoramic following the next page Capturing Stereoscopic 360 Screenshots and Movies from Unreal Engine 4 - Unreal Engine

I need to modify the plugin to make the two images into one and to make the shadows appear in the two images, but I have a problem with that. I have the plugin in the folder Engine/Plugins/Experimental. I can modify the SceneCapture.cpp easily, but I cant build the solution. I cant find the solution in the 4.13 folder (i am using the engine downloaded for the launcher, not for github source).

How can I build the plugin to apply the changes? Maybe is better to move the plugin to the project? If so, how can I build and execute the plugin?

Thanks for your time!
