Hi.
In one project I use Google’s ProtoBuf for network messages. And in .pro file I
have the next lines:
PRE_TARGETDEPS += $$PWD/messages.pb.cc $$PWD/messages.pb.h
QMAKE_EXTRA_TARGETS += protobufc protobufhprotobufc.target =
$$PWD/messages.pb.ccprotobufc.depends = FORCEprotobufc.commands = protoc
--proto_path=$$PWD --cpp_out=$$PWD $$PWD/messages.protoprotobufh.target =
$$PWD/messages.pb.hprotobufh.depends = protobufcHEADERS +=
$$PWD/messages.pb.hSOURCES += $$PWD/messages.pb.cc But every time when I
compile project this files generates and recompilation occurs. How can I do
that this files will generates only if they are not exists or if .proto file
was modified? Is it possible with qmake? Thanks.
