Release notes for CUDA Tookit (C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\CUDA_Toolkit_Release_Notes.txt) are copyrighted, so reluctant to attach.
Excerpt says:
"3.4. Deprecated Features
....
* 32-bit tools are no longer supported starting with
CUDA 10.0.
..."

Performed ./vcpkg install opencv[cuda]:x64-windows and it completed with no errors. [Took about 2 hours on 6-core Xeon system - yikes]

So, package build needs to be updated to accomodate 10.0+ version of CUDA toolkit. Perhaps continue support for x86-windows pre 10.0, deprecate support after?

Unfortunately cuda feature is unavailable with x86 triplets, only x64 ones work.
I will try to investigate how much difficult it would be to support x86 using an older version of cuda
