openCV的cmake中配置QT5路径

执行cmake移植opencv时出错,报错信息如下:

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

其中文翻译是:

 cmake / OpenCVFindLibsGUI.cmake上的CMake警告:18(find_package):
  找不到模块FindQt5Core.cmake或包的配置文件
 Qt5Core。

它给出的解决方法是把QT5中cmake的配置路径添加到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路径下定位这两个文件,locate Qt5CoreConfig.cmake ,找到两个目录:
locate Qt5CoreConfig.cmake
进入/opt/Qt5.3.2/5.3/android_armv7/lib/cmake/目录,QT5需要的配置路径都在这个下面;
QT5配置路径
依次将cmake中需要的路径都填上;
再次configure,就没有报错了,用generte生成Makefile;
