Is there any convention for where one stores installed software?

Question

I'm installing some software by cloning a git repo onto my local machine. I plan on creating a soft link to the binary made from the source in the repo to /usr/local/bin. Where should I put the git repo on my local machine? Is /usr/local/src the place?

Since you tagged this question "Darwin", I assume you use macOS. In which case, Xcode clones repositories by default to ~/Documents.

Another convention used to be used by System V, was to create individual project (or application distribution) directories in /opt. MacPorts does store its working directories in /opt/local by the way.

The "File Hierarchy Standard" has other recommendations.
