Question: Support for ProxyJump / proxy commands on Windows?

[DiamondSlug <DiamondSlug@xxxxxxxxxxxxxx>]

Hello libssh team,

First, thank you for the excellent library.

I have a question regarding the ProxyJump functionality (or proxy commands in general) on the Windows platform.

I am successfully using libssh to create SSH sessions with a ProxyJump, connecting from machine A to machine C through a jump host B. This works perfectly when all three machines are running Linux (Ubuntu).

However, when I try to run the same client code on a Windows machine (to connect to the same Linux hosts), I receive the following error: "The libssh is built without support for proxy commands"

I did a bit of digging in the source code, and it appears this might be intentional. I noticed in DefineOptions.cmake that WITH_EXEC is disabled for Windows, and it looks like the proxy command support in src/client.c is not implemented for Windows builds.

My question is: Is there a recommended way to achieve ProxyJump functionality when using libssh on a Windows client? Is there a different build flag I should be using, a known workaround, or is this feature currently unsupported on Windows?

Thank you for any guidance you can provide.

Best regards,

Daniel
