Standard library prefix on Windows

### Comment:

While working on a rust package using `libssh2` (see https://github.com/conda-forge/git-cliff-feedstock/pull/23#issuecomment-2695470356 and https://github.com/conda-forge/git-cliff-feedstock/pull/26, I found the windows build to fails with the following error:

Someone on Zulip spotted that the linker is looking for `ssh2.lib` while the library only contains `libssh2.lib`.

After adding `set "RUSTFLAGS=-l libssh2 %RUSTFLAGS%"` to the Windows build, everything works fine.

Doing a [GH search on conda-forge](https://github.com/search?q=org%3Aconda-forge%20CMAKE_SHARED_LIBRARY_PREFIX&type=code), we can see that a few feedstocks are setting manually `CMAKE_SHARED_LIBRARY_PREFIX` to either `"lib"` or `""`.

I am not sure which one is standard on Windows and/or conda-forge, and I am not sure whether there is a proper way to fix it (without having to do `set "RUSTFLAGS=-l libssh2 %RUSTFLAGS%"`).

There is no real actionable here and I only opened that ticket to let you know about the issue.
