Hello OpenCV

Dependencies

Just tinkering with the Open Computer Vision (OpenCV) library.

To install the library depencies on MacOS I used Homebrew.

brew install homebrew/science/opencv3 \
    --with-contrib \
    --with-ffmpeg \
    --with-gstreamer \
    --with-qt5

Homebrew gives some instructions for linking to the keg-only package, I won't cover that here now because it depends a lot on what is used for build tooling.

Use homebrew-installed libraries with pkg-config by adding the library's pkgconfig directory to PKG_CONFIG_PATH.

export PKG_CONFIG_PATH="/usr/local/opt/opencv3/lib/pkgconfig/:$PKG_CONFIG_PATH"

This can be loaded anywhere, but I recommend a tool like direnv or some other environment-file loader tool.

Goal

Just tinkering in C++ with OpenCV. Primarily trying to build something like Wesley the Augmented Whiteboard. I may try to get this working on a Raspberry Pi so that I can use it as a dedicated augmented whiteboard appliance in my office. Undecided at this time.
