I would say it is likely that the lack of a native C++ build tool helped Bazel to not have to compromise on how it integrates compilers into the system. I think that C++ is also just a good fit for the design; not all languages will. Interpreted languages fit into the system a bit less well in my opinion (but I still like that it is treated with some level of consistency.)
