[讨论]cmake生成QT输出动态库，隐性调用时链接错误2001 [复制链接]

具体的问题描述如下：
CMakeLists.txt文件内容如下：

cmake_minimum_required(VERSION 2.6)

PROJECT(testQt)

FIND_PACKAGE(Qt4 REQUIRED)

INCLUDE(${QT_USE_FILE})

SET(DLL_SOURCE testDLL.cpp)
SET(DLL_HEADER testDLL.h)
SET(EXE_SOURCE main.cpp)

QT4_WRAP_CPP(MOCSrcs ${DLL_HEADER})


ADD_LIBRARY(dllTest SHARED ${DLL_SOURCE} ${MOCSrcs})
ADD_EXECUTABLE(testQt WIN32 ${EXE_SOURCE})

TARGET_LINK_LIBRARIES(dllTest
  ${QT_LIBRARIES})

TARGET_LINK_LIBRARIES(testQt
  dllTest
  ${QT_LIBRARIES}
  ${QT_QTMAIN_LIBRARY})


testDLL.h文件内容如下：
#ifndef testDLL_h__
#define testDLL_h__

#define V_FRAME_WORK_EXPORTS
#if defined(V_FRAME_WORK_EXPORTS)
#define V_FRAME_WORK_EXPORT Q_DECL_EXPORT
#else
#define V_FRAME_WORK_EXPORT Q_DECL_EXPORT
#endif

#include <QPushButton>

class V_FRAME_WORK_EXPORT testDLL : public QPushButton
{
    Q_OBJECT
public:
    testDLL(QWidget* parent = 0);
    ~testDLL();
};
#endif // testDLL_h__

testDLL.cpp文件内容如下：
#include "testDLL.h"

testDLL::testDLL(QWidget* parent /* = 0 */):QPushButton(parent)
{
    this->setText("TestDll");
}

testDLL::~testDLL()
{

}
以上文件构成了DLL输出动态连接库项目

下面项目是调用项目，文件内容包括main.cpp

#include <QApplication>
#include "testDLL.h"
#include <QMainWindow>

int main(int argc, char** argv)
{
    QApplication app(argc, argv);

    QMainWindow mainWindow;    
    testDLL* dll = new testDLL(&mainWindow);


    mainWindow.setCentralWidget(dll);
    mainWindow.show();

    app.exec();
}

编译动态库的项目时，没有问题，但是当调用的时候就会产生一下错误：
1>------ Build started: Project: test, Configuration: Debug x64 ------

如果第一个库生成静态库，怎么没有问题，可以编译使用。求助各位，我的错误在哪里？QT是我自己编译的，X64 win7系统，VS2010
