windows binaries totally broken

[Oleg Eroshkin <ojero@xxxxx>]

Hi!

Published LIBSSH windows binaries are totally broken, because AES chipher is not supported. I maked binaries from sources, but the problem was not solved. 

The reason is CMake does found OpenSSL headers. The problem is in file "ConfigureChecks.cmake". It uses variable "OPENSSL_INCLUDE_DIRS" but CMake ("FindOpenSSL.cmake") initializes "OPENSSL_INCLUDE_DIR" (no "s" at the end). I fixed this, and now library works fine.
