Set environment variable for OpenSSL in CMake file (facebookincubator…

…#5309) Summary: Folly needs OpenSSL 1.1 version to function. In the presence of other OpenSSL versions, it is possible that folly in bundled mode can pick up other incompatible versions causing the build to fail. Currently, in the `setup-macos.sh` script, we set OPENSSL_ROOT_DIR=$(brew --prefix [email protected]). We require a similar change for the bundled folly installs as well. To achieve this goal, we now set the `OPENSSL_ROOT_DIR` environment variable via the CMake file to set the path to the correct version of OpenSSL.
