Somehow for a lot of people OpenCV goes very bad on macOS. I've created a github gist that will help you set it up properly on macOS. The issue i think arises when setting up the environment variables properly.

Here is a link to the gist. Please feel free to provide your feedback or if i might have missed anything. Will surely incorporate that in.

# Installing & Configuring OpenCV crate for rust on macOS

All of us have had some trouble setting up opencv create for rust-lang on macOS. In this article i will be showing you how to properly set up OpenCV so that when you build it you do not encounter any build issues.
###### opencv crate : https://crates.io/crates/opencv

###### Note: In this article we will rely on auto-detection of the OpenCV library, which is the best thing to do on macOS. So make sure to only set the environment variables that have been advised here. You do not need to set any thing variables that relate to OpenCV specifically.

`Tested on Following`

You have a syntax error at the end:

export DYLD_FALLBACK_LIBRARY_PATH="$(xcode-select --print-path)/Toolchains/Xcod$
