How to link to Pixy2 using CMake and C++

I bought a pixy2 to play with some computer vision, but it turned out now to be what I expected. Linking to the library and installing it was a bit of a pain, so I thought I'd create a repo in case you're interested in writing some C/C++ code for it.

The following steps are taken straight out of: https://docs.pixycam.com/wiki/doku.php?id=wiki:v2:building_the_libpixyusb_example_on_linux

 sudo apt install git libusb-1.0-0-dev g++ build-essential 
 git clone https://github.com/charmedlabs/pixy2 
 cd pixy2/scripts && ./build_libpixyusb2.sh 

Once libpixy2.a is built, they don't have an obvious way of installing the library to link to it. Inside this repo there's an install_libpixyusb2.sh script.

cp pixy2_example/scripts/install_libpixyusb2.sh pixy2/scripts/
cd pixy2/scripts/
sudo ./install_libpixyusb2.sh

This will install the headers and library file to /usr/local/

Now we can link to the library. Take a look at the cmake and examples directory.

mkdir build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j6
