Bazel

Bazel is a build system developed at Google to address the internal need to have a fast and scalable build system that can build any project no matter what the programming language is. Bazel supports building C, C++, Java, Go, and Objective-C projects. More than that, it can be used to build Android and iOS projects.

Bazel became open source around 2015. It is a build system, so it can be compared with Make and Ninja, but not CMake. Almost all of Google's open source projects use Bazel for their builds. For example, we can name Bazel itself, gRPC, Angular, Kubernetes, and TensorFlow.

Bazel is written in Java. It is famous for parallel and scalable builds, and it really makes a difference in big projects. Parallel builds are also available in Make and Ninja, both by passing the -j option (Ninja is parallel by default, however).
