Create GateKeepr exceptions for all files in a folder

I downloaded a software in tar.gz form. It is built from a bin folder and lib folder. It is blocked from running since files are from the Internet. I wanted to make an exception for the program yet there are many binary files. On the Internet I found how to add exceptions only to .app files. Is there a way to add exceptions for all files in a folder and sub folders? Maybe by a script?
