How to compile ssh withU2F-Support

Hi,
I am interested in an ssh-client with U2F-Support. I read the building page, but it fails to compile in CLI and GUI Mode.

first, I'm not sure if I should submit this issue to PowerShell/Win32-OpenSSH or PowerShell/openssh-portable. Could you please clarify which repo is good for what? I am from the Linux world and I am not exactly sure how to read the .sln file. Is it correct you have to manually update this file to make it work with Visual Studio 22?

How to attach log files to have them readable here? They seem to get scrambled.

Thanks,
Michael!

Start with contrib/win32/openssh/OpenSSHBuildHelper.psm1 and the Visual Studio build output from win32iocompat.vcxproj. Reproduce the CLI failure with Start-OpenSSHBuild and inspect the listed win32compat header errors and missing posix_compat.lib. Done means the documented Windows build completes successfully in both CLI and GUI modes.
