A fresh build of a large C++ project taking 1 hour does not sound strange at all.

If that's an incremental build though (i.e. simply rebuilding after changing a few files), there's something very wrong.

Your org needs better distributed build caching if you can't get that number lower. All builds should be "incremental" with appropriate caching.

It does if you have an even remotely reasonably specced development machine.
