I've followed all of the steps from this question: Highgui and ruby
opencv was installed via brew, and rb_webcam was installed via gem install.
require "opencv"
require "rb_webcam"
capture = Webcam.new
The error is:

In the other stackoverflow post from above, the the user made the post said that they-
"Solved it by downloading gem from here https://github.com/TyounanMOTI/rb_webcam and building and installing it manually."
My question is, how do I solve it by building and installing it manually?
(especially if 'gem install rb_webcam' isn't considered manual installation).
