| # Protocol Buffers GN Build Support |
| |
| This repository contains |
| [GN build system](https://gn.googlesource.com/gn/+/HEAD/) support for |
| [Protocol Buffers](https://github.com/protocolbuffers/protobuf). It's in its own |
| repository because it needs to be shared by |
| [Fuchsia](https://fuchsia.googlesource.com/fuchsia/) and |
| [Cobalt](https://fuchsia.googlesource.com/cobalt/). |
| |
| This repo should be checked out such that: |
| |
| * It is in `//build/secondary/third_party/protobuf`. |
| * Protobuf is in `//third_party/protobuf`. |
| * `//.gn` contains `secondary_source = "//build/secondary/"` |
| |
| See the |
| [GN documentation on secondary_source](https://gn.googlesource.com/gn/+/master/docs/reference.md#other-help-topics-gn-file-variables). |
