# 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.
