The cc_library rule is pretty much just "glob" calls expressing where the srcs, hdrs, and textual_hders are to be found.  I think bazel is not a good choice for the main Proj repo.

Bazel was mentioned as an example of a modern build system that has
gained some traction (thanks, Google!):

I first encountered CMake 10 years ago and thought it was rubbish.
So-called "Modern CMake" advancements and paradigms (i.e.
https://cliutils.gitlab.io/modern-cmake/) have helped its adoption. My
point is it's difficult to predict what build system will be popular
and fit-for-purpose in another decade from now, so I'd be hesitant to
say CMake will be the only build system from now on. Whatever it is,
it needs to be reliable and cross-platform to work equally on (e.g.)
NetBSD or MS Windows.
