# To compile protocol buffers with qt qmake, specify PROTOS variable and
|
|
|
|
|
# include this file
|
|
|
|
|
#
|
|
|
|
|
# Example:
|
|
|
|
|
# PROTOS = a.proto b.proto
|
|
|
|
|
# include(protobuf.pri)
|
|
|
|
|
#
|
|
|
|
|
# By default protoc looks for .proto files (including the imported ones) in
|
|
|
|
|
# the current directory where protoc is run. If you need to include additional
|
|
|
|
|
# paths specify the PROTOPATH variable
|
|
|
|
|
#
