我正在使用Qt和Protocol Buffer构建网络应用程序。我有一个可以成功编译的服务器和一个Qt客户端，它不能用Protocol Buffer编译。
通过在以下Makefile上运行make来构建服务器
PWD := $(shell pwd)
CXX := g++
LINKER := g++
INCDIRS := -I. -I$(PWD)/lib -I$(PWD)/lib/protobuf-2.6.1/src
LIBDIRS := $(PWD)/lib/protobuf-2.6.1/src/.libs

MODEL_DIR := model
MODEL_BUILD_DIR := build

MODELS := $(shell bash -c "cd $(MODEL_DIR) && ls *.proto")
MODELS_SRCFILES := $(patsubst %.proto, %.pb.cc, $(MODELS))
MODELS_OBJFILES := $(addprefix $(MODEL_DIR)/$(MODEL_BUILD_DIR)/, $(patsubst %.cc,%.o,$(MODELS_SRCFILES)))
INCDIRS += -I$(MODEL_DIR)/$(MODEL_BUILD_DIR)
SERVER_DIR := server
SERVER_SRCFILES := $(wildcard $(SERVER_DIR)/*.cpp)
SERVER_OBJFILES := $(addprefix $(BIN)/, $(patsubst %.cpp,%.o,$(SERVER_SRCFILES)))
SERVER_BUILD := $(BUILD_DIR)/server
CLIENT_DIR := client
QMAKE := qmake
LIB_DIR := lib
LIB_SRCFILES := $(wildcard $(LIB_DIR)/*.cpp)
LIB_OBJFILES := $(addprefix $(BIN)/, $(patsubst %.cpp,%.o,$(LIB_SRCFILES)))

客户端Qt项目使用此.pro：

由../model/build/*.model.pb.h生成四个protoc生成的文件，即make model。
我的问题是单独运行make model可以成功编译协议缓冲区实现文件。但是将它们包含为SOURCES并用qmake生成的Makefile编译它们不起作用。
错误如下：
