Installing OpenCV using Homebrew

Steps.md

Currently(10/12/2016) installing on Sierra has many problems.

1. Numpy Version, required 1.11.2, but brew install 1.11.1.
2. QT, QTKit Problem. (actually I don't know how to solve this. so I'm using ffmepg.)

Steps

1. Install with HEAD

   brew install opencv3 --with-contrib --with-ffmpeg --HEAD

2. Make symbolic link to pkg-config directory.

• If you were using OpenCV 2.x and OpenCV 3.x,

  `ln -s /usr/local/opt/opencv3/lib/pkgconfig/opencv.pc /usr/local/lib/pkgconfig/opencv3.pc`
  

• If you not

  `ln -s /usr/local/opt/opencv3/lib/pkgconfig/opencv.pc /usr/local/lib/pkgconfig/opencv.pc`
  

1. Test

   pkg-config --cflags --libs opencv3
