# This is the root build file for GN. GN will start processing by loading this
# file, and recursively load all dependencies until all dependencies are either
# resolved or known not to exist (which will cause the build to fail). So if
# you add a new build file, there must be some path of dependencies from this
# file to your new one or GN won't know about it.
# Use of visibility = clauses:
# The default visibility for all rtc_ targets is equivalent to "//*", or
# "all targets in webrtc can depend on this, nothing outside can".
#
# When overriding, the choices are:
# - visibility = [ "*" ] - public. Stuff outside webrtc can use this.
# - visibility = [ ":*" ] - directory private.
# As a general guideline, only targets in api/ should have public visibility.
