What is the darwinssl library location on Mac OS X?

Question

I am trying to compile curl and statically link it to another project. I did manage to compile it for my mac architecture(x86_64) and got "libcurl.a". Now when I try to build:

#include <curl/curl.h>

int main()
{
  CURL *curl = curl_easy_init();
}

with g++ tornado.cc -o tornado (path-to-where-it-is)libcurl.a -std=c++11

I get:

Undefined symbols for architecture x86_64:
  "_CFArrayAppendValue", referenced from:
      _append_cert_to_array in libcurl.a(libcurl_la-darwinssl.o)
  "_CFArrayCreate", referenced from:
      _darwinssl_connect_common in libcurl.a(libcurl_la-darwinssl.o)
  "_CFArrayCreateMutable", referenced from:
      _darwinssl_connect_step2 in libcurl.a(libcurl_la-darwinssl.o)
  "_CFArrayGetCount", referenced from:
      _darwinssl_connect_common in libcurl.a(libcurl_la-darwinssl.o)
  "_CFArrayGetValueAtIndex", referenced from:
      _darwinssl_connect_common in libcurl.a(libcurl_la-darwinssl.o)
  "_CFDataCreate", referenced from:
      _append_cert_to_array in libcurl.a(libcurl_la-darwinssl.o)

As I understand it wants to get links for darwinssl, but I do not know where to get those.

The readme for curl (https://github.com/biasedbit/curl-ios-build-scripts/blob/master/README.md) - does mention it depends on libz.dylib and Security.framework but does not give any clues about what they are, when and how do I need them, and how to include those.

P.S. the regular curl inclusion works fine: g++ tornado.cc -o tornado -lcurl -std=c++11

I found some time to mess around on the mac. Here's the command that worked for me:

gcc main.cpp -I path/to/include path/to/libcurl.a -framework Foundation -lz -framework Security

Basically, you need -framework Foundation, -lz and -framework Security.
