Installing OpenCV on Mac OS

Here is the official installation guide.

I'll show you how to build opencv from source using the CMake build system.

1.  Open Terminal. Move to a folder where you want to download opencv source code.

2. Type in the following commands.

$ svn co https://code.ros.org/svn/opencv/trunk/opencv
(This will download source code from repository)

$ cd opencv
(moving into the opencv folder just downloaded)

$ mkdir build
$ cd build
$ cmake ..

If you want to configure the make
$ ccmake .
(This will give you an opportunity to choose to build samples and install examples)

3. Build and install opencv
$ make -j8
$ sudo make install
