cmake编译opencv开源项目报错问题

最近使用cmake在编译一个配置了opencv环境的c++开源项目时遇到如下问题:

CMake Warning at D:/opencv4/OpenCVConfig.cmake:176 (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:13 (find_package)


CMake Error at CMakeLists.txt:13 (find_package):
  Found package configuration file:

    D:/opencv4/OpenCVConfig.cmake

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

于是查看了所有博客的方法，基本分为两类，一类是修改CMakeLis.txt文档，另一类是opencv版本或者vs版本问题，尝试了一圈基本都没有用。最后无意间发现在configure时没有选择x64，默认的是x86，选择x64之后就编译成功了，给遇到同样问题的同志一个参考！
