I have used Bazel (on Mac OS) to build a small C++ project. The nice thing about it is that it can be easily configured to download and build third-party dependencies from github. I have used this feature to add gflags, protobuf, and googletest dependencies to my project. That being said, it is still not perfect. For instance, I was not able to build GzipInputStream and GzipOutputStream (see e.g. https://github.com/google/protobuf/issues/2365).
