Can't build macOS project with Hermes

[teodorciuraru]

Environment

react-native -v:
react-native-cli: 2.0.1
react-native: 0.78.2
npm ls react-native-macos:
0.78.3
node -v: v22.16.0
npm -v: 10.9.2
yarn --version: 3.6.1
xcodebuild -version:
Xcode 16.4
Build version 16F6

Steps to reproduce the bug

1. Install react-native-macos inside a RN project.
2. Enabled Hermes in the Podfile:
   :hermes_enabled => true
3. cd macos; pod install
   While installing, under hermes-engine you will see:
   Fetching podspec for `hermes-engine` from `../node_modules/react-native-macos/sdks/hermes-engine/hermes-engine.podspec`[Hermes] Using the latest commit from main.
4. yarn macos or build from Xcode.

Expected Behavior

Building the macOS app successfully.

Actual Behavior

Xcode build will fail and you will get:

Node found at: /Users/teodorc/.nvm/versions/node/v22.16.0/bin/node
++ hermesc_dir_path=/Users/teodorc/.../example/macos/Pods/hermes-engine/build_host_hermesc

CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.

Command PhaseScriptExecution failed with a nonzero exit code```

I'm hinting there's a problem with the `hermes-engine` pod that forces using latest commit on `main`, which is not in sync with `react-native: 0.78.2`.

[Saadnajmi]

Just to confirm, are you using React Native macOS to build an iOS app?

[teodorciuraru]

@Saadnajmi, that was an oversight; I edited the text. I'm talking about a new standard RN macOS up and its usual setup and getting tangled in Xcode and Cocoapods issues around hermes-engine.
