Ceres Solver is an open-source C++ library for modeling and solving large, complex optimization problems. It is often used in computer vision and robotics applications.

A commit hook is a script that runs automatically when a commit is made to a Git repository. It can be used to enforce certain rules or perform certain actions.

Gerrit is a web-based code review system for Git repositories. It is often used in software development teams to manage the code review process.

Based on your statement, it seems that Ceres Solver is being used as a submodule in a Git repository, and a commit hook is being added to integrate with Gerrit for code review.
