在配置完opencv之后，cmake测试，出现下面的错误

$ cmake .
-- OpenCV ARCH: 
-- OpenCV RUNTIME: 
-- OpenCV STATIC: ON
CMake Warning at /Applications/opencv-3.1.0/cmake/OpenCVConfig.cmake:166 (message):
  Found OpenCV Windows Pack but it has no binaries compatible with your
  configuration.

  You should manually point CMake variable OpenCV_DIR to your build of OpenCV
  library.
Call Stack (most recent call first):
  CMakeLists.txt:10 (find_package)


CMake Error at CMakeLists.txt:10 (find_package):
  Found package configuration file:

    /Applications/opencv-3.1.0/cmake/OpenCVConfig.cmake

  but it set OpenCV_FOUND to FALSE so package "OpenCV" is considered to be
  NOT FOUND.

后来查到需要添加下面一句话

set(OpenCV_FOUND 1)

结果依然是上面的错误，后面又查到有人使用下面的方法

from opencv/build/ copy OpencvConfig.cmake and OpenCVModules.cmake to opencv/cmake/
then in you project delete file build and run again cmake .. and make

问题解决，原因未知。
