Most of the time you will be able to find something like a fallen tree or a pile of tree branches that you could hide behind (talk about easy setup).
I have never personally used a ground blind while big game hunting, but what I do is not to make any sudden or swift movements. I have taken plenty of deer at close range (less than 100 yards) that were looking at me - simply because I moved slowly while shouldering my rifle. Heck, I bought a 300 Win Mag many years ago so I could reach out and touch something - only to kill all but 1 deer at 75 yards or less.

Sounds like you have a good start by hiking and glassing. If you can figure out where the animals are going, you can get there ahead of them and surprise them - a ground blind may not be needed.
