From c59eb810728572fde84492d43a932dcac89746d6 Mon Sep 17 00:00:00 2001

Subject: [PATCH] EXIV2_ENABLE_SSH: Fix compatibility with >=libssh-0.9.2

0.9.1 remains broken regardless and is beyond fixing in this place.

Build-tested with both libssh 0.9.0 and 0.9.2.

Solution copied from KDE's kio-extras commit 24506c2af8d1904a99538543804306c6c2b81ca2
