Welcome! It's late for me and I'm on cold meds right now, so I'm a bit sleepy. I'll give more complete responses to any further questions later on.
Sorry, but there's no link. Go back to the start of this thread and give it a read. Download the Gurps Ruleset (post #1 in this thread) and put it in your Fantasy Grounds ruleset folder.
You can use GCA (Gurps Character Assistant) to create and export characters into FG (Fantasy Grounds), by putting the GCA export files (post #1) into your GCA folder, or you can also input stuff manually. There is a video of the process floating around, and I'll point you to tomorrow if no one has beaten me to it by then.
You can also export character sheets from GCS (Gurps Character Sheet) , but this is a relatively new option. There is a video about this as well.
