无法在CMake

Question

我正在关注this教程，使用CMake统一安装OpenCV。我坚持第6步。我已经在CMake中为源代码字段指定了源文件夹，并为目标创建了一个新文件夹。我测试了所有三个生成器选项，即Visual Studio 15 2017，Visual Studio 15 2017 win x64，Visual Studio 15 2017 ARM，

问题是我无法配置它。它说： 以下是CMakeOutput.log文件内容： -

  

系统是：Windows - 6.1.7601 - AMD64

以下是CMakeCache.txt文件内容： -

    CMake Deprecation Warning at CMakeLists.txt:72 (cmake_policy):
  The OLD behavior for policy CMP0020 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

我已经厌倦了昨天寻找这个错误的解决方案。所以，决定重新开始这一天。卸载所有组件。再次下载所有组件。再试一次。在第三或第四次调整中，我的工作就像没有任何问题。这个问题现在解决了，谢谢
