Issues compiling Qt project with Google Protocol Buffer - c++

Question

I am building a network application with Qt and Protocol Buffer. I have a server, which can be compiled successfully, and a Qt client, which cannot be compiled with Protocol Buffer.
The server is built by running make on the following Makefile
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
LIBS := -l protobuf
CXXFLAGS := -std=c++11 -pthread -g #-Wall -Wextra
BUILD_DIR=build
BIN := $(BUILD_DIR)/bin
PROTO := $(shell bash -c "pwd")/lib/protobuf-2.6.1/src/protoc
MODEL_DIR := model
MODEL_BUILD_DIR := build
BIN := $(BUILD_DIR)/bin
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)))

The client Qt project uses this .pro:
QT += core gui
CONFIG += c++11
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = client
TEMPLATE = app

unix:!macx: PRE_TARGETDEPS += ../lib/protobuf-2.6.1/src/.libs/libprotoc.a
The four protoc generated files, i.e. ../model/build/*.model.pb.h, is generated by make model.
My issue is that running make model alone can successfully compile the protocol buffer implementation files. But including them as SOURCES and compile them with qmake generated Makefile does not work.
The error is as follow:

What could be the problem??
