I find it weird to have the same library in both Libs and Libs.private.

Either it's a direct dependency of ssh2 and it should be in Libs. Or
it's an indirect dependency of ssh2 and should only be used when static
linking, in which case it should be only in Libs.private.

Section thing that looks weird is: why a full path to libmbedcrypto.a
and not a -l flag ?

That being said, the libcurl change looks good to me. Did you submit it
upstream ?

Thanks,
