Perhaps you should be building the V8 repo with GN (not Make) as a submodule of your git project.
The docs are here: https://v8.dev/docs/build-gn There are two scripts in the V8 repo that do the heavy lifting: v8gen.py (generates build files from configs) gm.py (runs the resulting build and most importantly installs all the resulting artifacts in the right places) I worked on a project recently that had forked V8 and built in a separate project and then imported the static library, etc into a CMAKE build that did not use submodules. That was very hard to maintain.
