Build OpenSSL CURL for android and iOS

Question

I'm writing a native C++ library for Android and iOS. This library will be used for answering web requests. For that i used a library can be found at "https://github.com/OlehKulykov/libnhr". There is a lots of problems and i will completed that problems and now it works fine. But, it wont support HTTPS(SSL) connections. I searched and i found for that i'd use OpenSSL and cURL libraries. For that, I used steps at "https://github.com/leenjewel/openssl_for_ios_and_android" for compile OpenSSL and cURL cross platform. Build is successfull at linux and MacOS. But, when i include manifested static files(libSSL.a, libCrypto.a, libcURL.a) into my c++ library, I can see lots of OpenSSL library methods except SSL methods. I cant succeed at this point. When i used available files at github, it gives me same result. I can use OpenSSL's crypto MD5 methods but when i try to use SSL methods, it gives me errors. This is an example method and its errors.

   CURL * curl =curl_easy_init();
   return NULL;
}
