How to set up component on another site?
Here's what I did:


Transferred component files from one site to the other to the same directory.
In the components.module file (which for me was up a couple of levels from the place I dropped the component files) paste in any hooks the correspond to the component (my component was an image gallery which used Masonry, so there were some hooks there).
Ensure the render function is relating to the right theme. See my other issue here for more info.
Clear caches, rebuild registry.


It's not the best response, but I hope it helps someone.
