VS2015 build openssl with boost asio

Question

I am compiling with Visual studio 2015 and Boost v1.61 and OpenSSL v"1.1.0-pre7-dev" (from OpenSSL Github). In accordance with what is said in the INSTALL file, I installed the OpenSSL like that (for the debug mod):

$ perl Configure VC-WIN32 --prefix=D:/OpenSSL/build/debug --debug
$ nmake
$ nmake test
$ nmake install

In the project setting, I added :

• The include directory path in the "C/C++ - General "(D:/OpenSSL/build/debug/include)

• The lib directory (D:/OpenSSL/build/debug/lib) in the "linker - general - other dependencies"

I use the c++ boost asio SSL library but when I build the project I have this error (see this pastebin for the full output):

I noticed that even if I omits to add the lib directory in the linker I have the same error.

Why am I getting the compile error?

EDIT 1:

Thanks to the jww's answer, indeed, the 1.1.0 version of OpenSSL is incompatible with the current version of Boost. I downloaded the OpenSSL 1.0.2h and this works well.
