Is there clear, step-by-step documentation on how users can

• find the MOM5, CICE5, libaccessom2 source code used by a given executable, and
• build custom executables with modified sources?

There are some users (e.g. @kialstewart) who will need to build their own executables, but I couldn't find this info documented anywhere. Apologies if I didn't look carefully enough...
