These are all 4 examples built using the .toml environment and their corresponding .spec files in the "examples" folder.
HaarCascade exists and should work, but is too slow for 30fps.
Examples come in two flavors per OS: CONSOLE and no console. The CONSOLE versions are for bugtesting. In case something goes wrong, try the CONSOLE version and if the console disappears too fast then try to screen record it/printscreen it and report the bug to me.
Mac examples use their corresponding *mac.spec file in the examples folder. They might take a while to load, use Activity Monitor if you suspect they don't work.

For Windows if you need to unzip .7z you can use 7zip.
