It looks like you're explicitely defining --with-openssl:

http://libssh2.cvs.sourceforge.net/viewvc/libssh2/libssh2/configure.in?revision=1.63&view=markup

   79 AC_ARG_WITH(openssl,
   80   AC_HELP_STRING([--with-openssl],[Use OpenSSL for crypto]),
   81   use_openssl=$withval,use_openssl=auto)

   86 # Look for OpenSSL (default)
   87 if test "$use_openssl" != "no" && test "$use_libgcrypt" != "yes"; then
   88   AC_LIB_HAVE_LINKFLAGS([ssl], [crypto], [#include <openssl/ssl.h>])
   89 fi
   90 

Is this the recommended usage?
