Xamarin IOS Linking issues when also using OpenCV (EMGUCV wrapper)

[SuperCD]

Dear ONNX community,
I'm working on a project that uses both OpenCV and ONNX for some specialized text recognition purposes.
We are developing the mobile application on Xamarin with targets for both Android and IOS.
For the OpenCV part we are using the EmguCV library (version 4.5.5.4823) and for ONNX we are using ONNXRuntime from the nuget repository, Microsoft.ML.OnnxRuntime (version 1.14.0).
The issue I am experiencing is that on iOS the build process stops at the linking phase of the main application with this kind of errors:

/MTOUCH: Error MT5212: Native linking failed, duplicate symbol: ''google::protobuf::internal::EpsCopyInputStream::ReadArenaString(char const*, google::protobuf::internal::ArenaStringPtr*, google::protobuf::Arena*)''. (MT5212)

I've tried to change the MTOUCH --registrar setting to static (as some sources suggest) but the error is there with static set.
While if I don't set it to static I have a similar but different error:

• /MTOUCH: Error MT5212: Native linking failed, duplicate symbol: ''_VP8DecompressAlphaRows''. (MT5212)
• /MTOUCH: Error MT5213: Duplicate symbol in: /obj/iPhoneSimulator/Debug/mtouch-cache/WebP.a(libwebpdecode_la-alpha_dec.o) (Location related to previous error) (MT5213)

They are essentialy the same kind of error, but on different library depending on how i set the behavior of the linker (or if I build for a simulator vs actual device, which actually changes the default for the same setting).

I've written to the EMGU support and they said that it is not their fault as they follow the correct procedure for including libraries that should lead to the linker excluding duplicated libraries automatically, and suggested me to write to the developers of ONNX for a solution.

Do you have any suggestion on what I might try to do?
