CURL should be compiled on machine and with openssl libs:

1. Install openssl by typing:

       # sudo apt-get install libssl-dev

2. Identify the openssl location in machine:

       # openssl version -d

   • Example:
     "/usr/local/ssl"
3. Download and extract desired curl version(latest recommended) project, one posibility for example:

       # wget http:https://curl.haxx.se/download/curl-7.50.3.tar.gz
       # tar -xvf curl-7.50.3.tar.gz

4. Go to Curl project and compile with openssl option:

       # cd curl-7.50.3
       # ./configure --with-ssl='/usr/local/ssl'
       # make 
       # make install

   • Note: Default path for --with-ssl option is /usr/local/ssl and this is the default path for openssl installation as well, but it can change, type ./configure --help inside curl project for help in options of compilation.
