Error: Building package curl:x64-linux failed with: BUILD_FAILED
Please ensure you're using the latest portfiles with `./vcpkg update`, then
submit an issue at https://github.com/Microsoft/vcpkg/issues including:
  Package: curl:x64-linux
  Vcpkg version: 2020.11.12-unknownhash

Additional context
The command idn2 works, and vcpkg install idn2 says it doesn't find unistring.

Thank you

Pleae rebuild libidn2 and try again.

Thanks.

Tried yay -S libidn2 and installed multilib and core versions, still returning the same error

For workaround, please remove libidn2 you manually installed and try again.

Thanks.

I removed the multilib, but I can't remove the core version :

> yay -R libidn2

Same error still appears when I try again.
