Yeah, I vacillated over the weekend and found that it's pretty easy to have CMake completely handle the build/install of Python extensions, but...

Yes, distutils would probably be the more standard/robust way if it were a completely independent component.  But if we want to provide a "unification interface" to have it built as part of a larger Bro source distribution via CMake, then it would be even less standard to have CMake delegate to distutils rather than do it itself.  It definitely "feels" like I would be abusing CMake by mixing it with a completely different build system.

Maybe one way to go is to provide both a CMake build system and a distutils one (separated), so that people that need the extra robustness (e.g. developers/packagers) can still use the setup.py while people that just want to build Bro from source can follow our established CMake method.  Not quite sure what the best option is for that use-case yet.
