使用 IE（推理引擎）编译时 OpenCV 构建错误

Question

OpenCV版本：4.4.0（最新） OpenVINO 版本：2020.4（最新）

试图在 Windows 10 上构建由 CMake 3.18.0 生成的项目时发生错误。试了很多次从头开始构建（清除所有缓存，更新源码，重装OpenVINO工具包，运行全部demo成功），问题依旧

这是 VS 2019 构建错误日志：

最后 10 个失败：

========== 构建：86 次成功，10 次失败，0 次更新，0 次跳过 ==========

注意：之前我可以使用 IE 构建 OpenCV 没有任何错误，但在新版本中编译和构建时出现很多错误。

有解决办法吗？

如果需要，我准备提供更多日志和信息。

谢谢！！

问题已通过使用 ngraph 标志配置 CMake 并定位其 CMake 文件 DIR 位置来解决。
