執行cmake移植opencv時出錯，報錯資訊如下：

CMake Warning at cmake/OpenCVFindLibsGUI.cmake:18 (find_package):
  Could not find module FindQt5Core.cmake or a configuration file for package
  Qt5Core.

其中文翻譯是：

 cmake / OpenCVFindLibsGUI.cmake上的CMake警告：18（find_package）：
  找不到模組FindQt5Core.cmake或包的配置檔案
 Qt5Core。
 

它給出的解決方法是把QT5中cmake的配置路徑新增到QT5_Core_DIR中；

  Adjust CMAKE_MODULE_PATH to find FindQt5Core.cmake or set Qt5Core_DIR to
the directory containing a CMake configuration file for Qt5Core.  The file
will have one of the following names:

  Qt5CoreConfig.cmake
  qt5core-config.cmake

使用命令在QT路徑下定位這兩個檔案，locate Qt5CoreConfig.cmake
