Ошибка компоновщика Gmock ==> множественное определение (с помощью cmake)

/ 11 мая 2018

Я столкнулся с ошибкой в ​​googlemock, и я могу скомпилировать и запустить проект, используя eclipse и мой cmake, используя только один файл Test.cpp, используя следующий код, но ошибку, используя мой ложный класс. Пожалуйста, мне нужна помощь. Большое спасибо. 

#include <gtest/gtest.h>
#include <gmock/gmock.h>

using namespace std;
using namespace testing;

class mxDriverInterface
{
    public:
        mxDriverInterface(){}
        virtual ~mxDriverInterface(){}
        virtual bool isReady(void) = 0;
};

class mxDriverImpl : public mxDriverInterface
{
     public:
        mxDriverImpl(){}
        bool isReady(){return true;}
};

// A mock mxDriver class
class MockMxDriver : public mxDriverInterface
{
    public:
       MockMxDriver(){}
       virtual ~MockMxDriver(){}
       MOCK_METHOD0(isReady, bool());
};

TEST(checkMockMx, instance)
{
    EXPECT_TRUE(4 != 5);
}

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

=============================================== ============================ 

[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from checkMockMx
[ RUN      ] checkMockMx.instance
[       OK ] checkMockMx.instance (0 ms)
[----------] 1 test from checkMockMx (0 ms total)
[----------] Global test environment tear-down
[==========] 1 test from 1 test case ran. (0 ms total)
[  PASSED  ] 1 test.

=============================================== ===========================

Но просто создаю экземпляр моего класса MockMxDriver следующим образом: 

TEST(checkMockMx, instance)
{

MockMxDriver mockMxDriver; 

EXPECT_TRUE(4 != 5);

}

... проект завершается со следующей ошибкой:
