UPDATE

This question helped me also in finding the solution. Boost SSL with Visual Studio 2010 and OpenSSL

The steps required to use the openSSL lib with VS2012:

• download and install a version (I have 64bit OS, however I installed 32bit openssl) from http://slproweb.com/products/Win32OpenSSL.html.
• New project in VS, then Configuration Properties/C/C++/General/Additional Include Directories: openssl include folder (C:\OpenSSL-Win32\include)
• Linker/General/Additional Library Directiories: C:\OpenSSL-Win32\lib
• Linker/Input/Additional Dependencies :
• libeay32.lib libeay32MTd.lib libeay32MT.lib libeay32MDd.lib libeay32MD.lib ssleay32.lib ssleay32MTd.lib ssleay32MT.lib ssleay32MDd.lib ssleay32MD.lib

(It was written that I need to only add that one which matches with C/C++/Code Generation/Runtime Library, but It works me this way.)

将theese文件复制到当前的VS文件夹/ VC/lib中

这对我有所帮助
