Cannot open input file 'opencv_world320.lib'

[Robotuner]

Hi, thank you for your work! I have been following your video at https://www.bing.com/videos/search?q=face+detection+using+opencv+and+xamarin+forms&docid=607996704862569156&mid=E06ADF6EBF83A6D81153E06ADF6EBF83A6D81153&view=detail&FORM=VIRE with the current version of OpenCvSharp. After I get OpenCvSharp converted from PCL to netStandard and try to build I get errors telling me that Nuget packages are missing for OpenCvSharp.Windows\Xamarin.Forms.4.4.0.99164 and OpenCvSharpExterDroid\Xamarin.Forms.4.4.0.99164. I also get a link message: cannot open input file 'opencv_world320.lib'

I'm thinking that is it is opencv_world320.lib that is causing the Nuget package missing messages, but I don't know. The version of Xamarin Forms I am using is 4.8.0.1451, not 4.4.0.99164

I found the opencv_world320.lib in the OpenCvSharp directory, but do no know what to do with it.

Thank you.
