How do I get ep1+ep2+css content in the same SDK config?

I googled but I only found how to make the config for gmod. I want a full gmod one with EP2, ep1, and css props.
Any tutorial would be great.

Extract the content from the gcfs located in steam\steamapps into the appropriate directories in ep2.

Oh is that the only way?

Yes.

Idk if you need that info, but I thought I’d post it. Got it saved and all.
