为什么我不能为zmq编译基本的发送和接收模拟

Question

我正在zmq.hpp中为socket_t :: send和socket_t :: recv写一个gmock（仅zmq c ++标头绑定器）

zmq_mock_class.h

#pragma once

namespace zmq {
class ZmqMockSocketClass {
public:
  virtual size_t send(const void *buf_, size_t len_, int flags_ = 0) = 0;
  virtual size_t recv (void *buf_, size_t len_, int flags_ = 0) = 0;
};

}

zmq_mock.h

#include "zmq_mock_class.h"
#include <gmock/gmock.h>
#include <zmq.hpp>

class ZmqMockSocket : public zmq::ZmqMockSocketClass {
public:
  MOCK_METHOD3(send, size_t(const void *buf_, size_t len_, int flags_));
  MOCK_METHOD3(recv, size_t(void *buf_, size_t len_, int flags_ ));
};

zmq_test.cc

using  ::testing::_;
using  ::testing::AtLeast;
TEST(ZmqSendTest, TestSendErrorAgain)
{    
   ZmqMockSocket zmq_local;
}

int main(int argc, char **argv) {
  testing::InitGoogleTest(&argc, argv);
  return RUN_ALL_TESTS();
}

CMakeLists.txt：

cmake_minimum_required(VERSION 2.6)

# Locate GTest
find_package(GTest REQUIRED)
#find_package(GMock REQUIRED)
find_package(PkgConfig)
pkg_check_modules(GMOCK "gmock" REQUIRED)

include_directories(${GTEST_INCLUDE_DIRS})

# Link runTests with what we want to test and the GTest and pthread library
add_executable(runTests test/zmq_test.cc)
target_link_libraries(runTests ${GTEST_LIBRARIES} ${GMOCK_LIBRARIES} pthread zmq)
target_include_directories(runTests SYSTEM PRIVATE inc)

编译错误：

Google测试框架的构建和安装存在问题。从apt包中卸载Google测试

sudo apt remove google-mock
sudo apt-get remove googletest
