cmake 在 opencv c++ 项目中不起作用

Question

我需要你的帮助 ！我在这个链接中有这个 C++ 代码

[链接] https://github.com/royshil/FoodcamClassifier

两天以来我一直在尝试编译它，但我失败了，他们说我必须使用 cmake，我尝试了“GUI 版本，但它给了我与 cmake 本身相关的错误。所以我选择了cpp 和头文件并创建了一个新项目，但我现在有 100 个与 opencv 库相关的错误，我向上帝发誓我确信我的项目中包含文件夹和它的库！不知道这是怎么回事它 ！

任何的想法 ？

这是错误：

'CMake 错误：无法打开缓存文件进行保存。C:/Program Files/CMake 2.8/bin/CMakeCache.txt
CMakeLists.txt:4 (FIND_PACKAGE) 处的 CMake 错误：
  找不到模块 FindOpenCV.cmake 或包的配置文件
  开放简历。

  调整 CMAKE_MODULE_PATH 以找到 FindOpenCV.cmake 或将 OpenCV_DIR 设置为
  包含 OpenCV 的 CMake 配置文件的目录。该文件将
  具有以下名称之一：

    OpenCVConfig.cmake
    opencv-config.cmake



OpenCV_DIR-NOTFOUND
配置不完整，出现错误！
CMake 错误：无法打开缓存文件进行保存。C:/Program Files/CMake 2.8/bin/CMakeCache.txt
CMake 错误：：系统错误：权限被拒绝
CMake 错误：：系统错误：权限被拒绝 '

在 Linux 上我执行了以下操作：

$ git clone https://github.com/royshil/FoodcamClassifier.git
$ cd FoodcamClassifier/
$ mkdir build
$ cd build/
$ cmake ../
