我一直在尝试从两天来compaile它，我失败的
他们说我必须使用cmake，我试过GUI版本，它给我的错误realted到cmake本身
所以我拿了cpp和头文件，并做了一个新的项目但我现在有100个错误与opencv库相关，我发誓上帝我确定包含文件夹和它的libs在我的项目！不知道是什么问题！

and I've been trying since two days to compaile it , and I've failed they say that I have to use cmake , I've tried the "GUI version and it gave me errors realted to the cmake itself . so I took the cpp and header files and made a new project but I have now 100 errors related to the opencv library and I swear to god I'm sure of the include folders and the libs of it in my project ! don't know what's the matter with it !

以下是错误：

'CMake Error: Unable to open cache file for save. C:/Program Files/CMake 2.8/bin/CMakeCache.txt
CMake Error at CMakeLists.txt:4 (FIND_PACKAGE):
  Could not find module FindOpenCV.cmake or a configuration file for package
  OpenCV.

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

    OpenCVConfig.cmake
    opencv-config.cmake



OpenCV_DIR-NOTFOUND
Configuring incomplete, errors occurred!
CMake Error: Unable to open cache file for save. C:/Program Files/CMake 2.8/bin/CMakeCache.txt
CMake Error: : System Error: Permission denied
CMake Error: : System Error: Permission denied '

推荐答案

您可能需要在 CMakeLists.txt 之前 FIND_PACKAGE（OpenCV必填） （在我的情况下）：

SET("OpenCV_DIR" "PATH/TO/CMake/build")

在我的安装中，它解决了这个问题，因为上述文件位于build文件夹中。

In my installation it solved the problem since the mentioned files are located in the build folder.
