【问题描述】：
我从他们的 github 和他们的网站安装了 OpenCV 和 OpenCV contrib 4.1.2，以便在 Visual Studio 中使用他们的 dnn 模块。我一直无法让 CMake 配置和生成任何必要的内容。
这是我遇到的错误：

我在谷歌搜索时发现的另一篇帖子说 Python 路径可能不正确，但是当我在 cmd 中输入 python --version 时，它告诉我 Python 3.7.4
【问题讨论】：
-
你需要 contrib 中的额外模块吗？几周前我构建了 opencv 4.1.2，当我使用额外的模块构建时，我也遇到了很多问题。我在没有额外模块的情况下构建它，目前我没有遇到任何问题
-
您尝试为哪种语言构建 OpenCV？
-
是的，我需要 dnn 模块，它在没有贡献的情况下抛出了 100 多个编译错误。
-
我正在尝试为 C++ 构建它
-
您是否尝试过通过vcpkg 安装openCV。我已经通过 vcpkg 安装了它，但我不确定是否在那里构建了额外的模块。
