CMAKE tests generation under windows leads to linking error

[vtellier]

While trying to execute the tests I struggled a bit with their compilation.
The documentation (tests/README.md) says:

Building tests in Windows

Install CMAKE
CMD> CMAKE libzmq/tests
CMD> tests.sln
CMD> # build all projects in the solution

However I was faicing linking error on libzmq.lib.
After researches I found out these comments in tests/CMakeLists.txt:

# This is the output for Debug dynamic builds on Visual Studio 6.0
# You should provide the correct directory, don't know how to do it automatically
find_path(LIBZMQ_PATH "libzmq.lib" PATHS "../bin/Win32/Debug/v120/dynamic")

I just changed v120 to v140 as I am under Visual studio 2015 and it worked.
The thing is that it was the first time I used CMAKE so I spent some time trying to spot it.

Would it be possible to add a line about that in tests/README.md, or to make this fully automatic?

Please do send a PR to update the README and I'll merge it.

I'm not a Windows expert so not sure if it can be automated, hopefully someone else can help here.

For me the note in the README file is fair enough, would you like me to close the issue or should I keep it open until a Windows expert goes further?

Let's close it for now, if someone else on Windows wants to try and automate this they will
