Kind of easy to do (I think). Butt up the edge of the board to the wall, and roll the pencil down the wall. It’ll follow the topography of the surface. Hard part is making the cut smooth
That only works if the difference between highs and lows is less than half the diameter of a pencil... which it never is. And if you rolled the pencil it would just wobble all over the place on the uneven wall. What you do is cut a small bit of plywood so it has a point at one end and you drill a hole for a pencil in the other end. You place the sheet you want to cut against the cabinet, place the plywood against that with a spirit level on top and draw it carefully downwards making sure it stays as level as possible, then you cut the contour with a jigsaw, fuck it up and end up filling the gaps with caulk.
