Receiving error when executing the step 3 of installing Socket.IO C++ Client

Question

I want to install Socket.IO C++ Client from "https://github.com/socketio/socket.io-client-cpp", but I have some difficulties following the steps from "https://github.com/socketio/socket.io-client-cpp/blob/master/INSTALL.md". I have successfully installed boost version 1_73_0 (step 1) and run step 2. I have some difficulties with step 3. When I run cmake -DBOOST_ROOT:STRING=/Users/Home/Documents/boost_1_73_0 -DBOOST_VER:STRING=1.73.0 ./ I receive this error:

My environment is mac and I installed boost at /Users/Home/Documents/boost_1_73_0 and Socket.IO C++ Client is at /Users/Home/Documents/GitHub/socket.io-client-cpp

I also installed the static version of boost by ./b2 link=static,shared

I would appreciate it if you let me know what is wrong. I also tried BOOST_LIBRARYDIR as well, but it was not helpful. I am very new to programming, so I would be grateful if you make your answer as simple as possible.

I don't see a Boost error. The error I do see says, "Could NOT find OpenSSL...." Do you have OpenSSL libraries installed? — metal, Aug 03 '20 at 21:48
Thanks @metal. Yes, and when I run `brew install openssl`, I receive this: `Updating Homebrew... ==> Auto-updated Homebrew! Updated 1 tap (homebrew/core). ==> Updated Formulae Updated 5 formulae. Warning: openssl@1.1 1.1.1g is already installed and up-to-date To reinstall 1.1.1g, run `brew reinstall openssl@1.1`` so it is already installed — UnesBeig19, Aug 03 '20 at 21:52
I suggest you set `OPENSSL_ROOT_DIR` to the right spot, as the error message hints. (Disclaimer: I'm not a Mac user.) The comments on [this answer](https://stackoverflow.com/a/17231736/201787) suggest that this is a feature, not a bug, since it prevents you from accidentally linking to old versions of OpenSSL. — metal, Aug 03 '20 at 22:03
