21# This file defines a GN source_set for an external installation of protobuf.
22# To use, checkout the protobuf source into a directory, then set the build arg
23# dir_pw_third_party_protobuf to point to that directory. The protobuf library
24# will be available in GN at "$dir_pw_third_party/protobuf".
25#
26# This is known to work with commit 300dfcc5bf46d0fae35146db2195891df4959e4 in
27# the protobuf repository. These targets may not work with other versions.
28#
29# If the dir_pw_third_party_protobuf build argument is not set, the protobuf
30# targets are effectively disabled.
