Cannot build FFMPEGINTEROP with Visual Studio 2017

I've been fiddling with this for a few hours now. I've been trying to follow the infamous instructions to build the ffmpeginterup with the arm version of Visual Studio 2015. I have 2017 and have no use for 2015... So the instructions don't work at the line:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Visual Studio 2015\Visual Studio Tools\Windows Desktop Command Prompts\VS2015 x86 ARM Cross Tools Command Prompt

Since the ARM Cross Tools is not part of 2017.

I've beem trying to find alternate ways without success, looking through all forums, but there must be something I'm missing.

In 2018 (almost 2019!) is there a way to build ffmpeginterop with VS 2017? If yes, anyone could point me to the proper script/solution/instructions?

And there is something I must be missing here., Why is it not possible to download this already built for an X86 or x64 machine?

Thank you so much!

Start by reviewing the build instructions that reference the Visual Studio 2015 ARM Cross Tools Command Prompt and compare them with the available Visual Studio 2017 setup. Confirm whether FFmpegInterop can be built with Visual Studio 2017, then document the supported commands or explain the supported alternatives.
