I know how to technically do it, but how do you guys do it, when there's always wind? Do you shoot inside a building to get perfect windage zero? Is there some kind of trick or do you just live with the +/- margins?
How to zero windage on scope?

Just do it in the house, bore sight on a small target within the room and adjust windage.
Later, at the range, I'll fine tune at 50 yards and then move to 100 to verify.
I'll usually be within one click increment on whatever scope I have mounted by then.
The effects of wind at those distances can pretty much be ignored.

Use a sheet of paper with a vertical line down the center. Post on a cardboard backer at a short distance (20-50 yards, depending how much wind you have) and use a level when posting the paper to the backer to ensure the vertical line is plumb/vertical. Aim at the vertical line and don't worry about elevation. Make adjustments as necessary to zero windage.
The best way is to mechanically center both the W and E erectors, then take a small box and cut V's in either side, lay the optic across the box and in the V's, then slowly rotate the optic to confirm that the crosshair spins on an axis / point.
If on the other hand your asking about the effect of wind while zeroing and trying to isolate / account for the variable? If you're shooting a centerfire cartridge at 100 yards / meters - unless we are talking storm force winds - wind will not demonstrably effect the bullet / POA / POI.
Draw a dot on the target big enough that you can see it at 100 with your own eyes (@ 1" circle), then draw a second 1/2" dot. Pull the bolt, center the bore on the 1" dot, review the relationship of the POA derived from centering the bore through the optic, make gross adjustments. Fire 2 rounds and confirm gross adjustment, make final adjustments, and line up on the 1/2" dot. Fire a 5 round group for final confirmation. Pack your shit up. Go shoot at a distance with a solid zero.
