In the C++ world, there's no "standard" build system that would work for in all supported use cases and on all supported platforms.
Therefore, gRPC supports several major build systems, which should satisfy most users.
+Note that this section only covers the build of gRPC itself, not the installation. See the [How to use](https://github.com/grpc/grpc/tree/master/src/cpp#to-start-using-grpc-c) instructions
+for guidance on how to add gRPC as a dependency to a C++ application (there are several ways and system wide installation is often not the best choice).
