Rather than +requiring ``GN`` to build or writing our own build definitions for these projects, +we have support in the build system for translating GN configuration +files into moz.build files. In most cases these moz.build files will be like any +others in the tree (except that they shouldn't be modified by hand), however +those updating vendored code or building on platforms not supported by +Mozilla automation may need to re-generate these files. This is a per-project +process, described in dom/media/webrtc/third_party_build/gn-configs/README.md for +webrtc. As of writing, it is very specific to webrtc, and likely doesn't work as-is +for other projects. |
