Build failure on Mac

[sudison]

Build failure with the following message:

Undefined symbols for architecture x86_64:
"_X509_get_signature_nid", referenced from:
wangle::SSLContextManager::insert(std::__1::shared_ptrwangle::ServerSSLContext, bool, wangle::SSLContextManager::SslContexts&) in libwangle.a(SSLContextManager.cpp.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

The solution is to specify correct openssl directory, such as:

cmake -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOPENSSL_LIBRARIES=/usr/local/opt/openssl/lib/

This is fixed using openssl-1.0.2+. Wangle builds for me on OSX using openssl-1.0.2o and the cmake command above.

This worked for me, but I had to clean the environment first (git clean -fdx) before I'd stop getting the error, despite running cmake. Left over object files, I guess.
