How to build Source code(with a little modify) to exec in order to get ocr(exec)?

<img width="1053" alt="image" src="https://user-images.githubusercontent.com/75168610/193424186-1be82b83-db2f-4a64-9009-2fde19edcea8.png">
As this image show, I compiled the code but ocr(exec) is red, and I can not find the location of it.
How can I get ocr(exec) compiling by myself just like I download by curl or homebrew?
