Hi Alexander,

I tried to use CMake, as you offered, in order to generate a VS2003 project
file, but encountered some errors.
I used the CMake GUI with the source code folder: "C:\...\libss2-1.7.0\src"
and I got these errors in the output window:
-------------

CMake Error at CMakeLists.txt:38 (include):
  include could not find load file:

    CheckFunctionExistsMayNeedLibrary

CMake Error at CMakeLists.txt:42 (include):
  include could not find load file:

    CheckNonblockingSocketSupport

CMake Error at CMakeLists.txt:43 (include):
  include could not find load file:

    SocketLibraries

CMake Error at C:/Program Files (x86)/CMake
2.8/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108
(message):
  Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the
  system variable OPENSSL_ROOT_DIR (missing: OPENSSL_LIBRARIES) (found
  version "0.9.8j")
Call Stack (most recent call first):

CMake Warning (dev) in CMakeLists.txt:
  No cmake_minimum_required command is present. A line of code such as

    cmake_minimum_required(VERSION 2.8)

  should be added at the top of the file. The version specified may be
lower
  if you wish to support older CMake versions for this project. For more
  information run "cmake --help-policy CMP0000".
This warning is for project developers. Use -Wno-dev to suppress it.

Configuring incomplete, errors occurred!

In addition, I looked at the CMakeError.log file and see other error:

Determining if files windows.h;bcrypt.h exist failed with the following
output:

For some reason, it looked for wincng library while I use OpenSSL.
What do I miss? which options should I add?

Thanks,
