Summary:
Within the `hermes-engine.podspec` contained in the RN repo (at `react-native/main/sdks/hermes-engine/`), there's a bit of logic that triggers `./utils/build-ios-framework.sh` and `./utils/build-mac-framework.sh` .
The issue is that we all thought that that `./utils/build-ios-framework.sh` would invoke the React native version of the scripts (since the podspec file lives right next to the `utils` folder) but, in reality, it doesn't. It just so happens that the Hermes repo has a root level `utils` folder which is (you guessed it) where the Hermes variation of those build scripts live.
So, when running the pod install command in a react-native project (build from source), it will go and download the hermes source code (since the `source[:git]` gets set) but then it will use the **hermes** variation of the `build-*.sh` scripts.

Pull Request resolved: https://github.com/facebook/react-native/pull/34704
Create separate hermes-engine tarballs for release and debug builds, and only include the debugger in debug builds.
Changes the hermes-engine podspec to use a debug Hermes build by default in order to preserve the inclusion of the debugger.
Upcoming changes should split the hermes-engine Pod to allow Xcode to use release and debug builds as needed.

When building Hermes for React Native, point to the React Native JSI location to ensure both React Native and Hermes use the exact same version of JSI.

Summary:
Use pre-built hermesc if available by generating a ImportHermesc.cmake file that points to the hermesc binary. Recent `react-native` releases should have hermesc available in sdks/hermesc.
Hermes build scripts have been updated to support a `HERMES_OVERRIDE_HERMESC_PATH` envvar which can point to this generated ImportHermesc.cmake file.

Summary:
Hermes' build scripts use the Ninja build utility if available, otherwise they default to Unix Makefiles. When Unix Makefiles were used, builds would take far too long due to the use of a single core.
To reduce the surface area of issues that may arise as we switch to building Hermes from source, we will now focus on a single build system using Unix Makefiles. We will also ensure all available cores are used when building on macOS.
