Most of these are also provided by Xcode, but notably when `doxygen` is picked up, it also creates some extra documentation. This all works smoothly, but it would not create a consistent build across various installs. Is there a canonical way to avoid such problems?

In the worst case, you may have to dig around inside the build system and patch it.
