title: Configured eclipse for gtkmm and gtk+ on ubuntu
body: <p>I am trying to configure latest Eclipse for C++ (Oxygen) to work with gtkmm. How can I remove errors from Eclipse such as unresolved symbols and gtkmm header files.</p>
  
  <p>I am able to compile from command line using g++ and pkg-config flags. How can I do same thing from the Eclipse IDE?</p>
  
  <p>I am using latest IDE 2019 version.</p>
