[Qt-creator] Additional libraries in my project

[Kosta]

Hello, 
I have to use the SNMP++ library in my project. But I'm not sure how to add it. I have a .tar file "snmp++v3.2.23.tar", I think I should unrar it and place the "include" and "src" directories in my project folder in the workspace ? I am worried, because as far as I know there is no support for subfolders yet. 
What is the correct approach here ? I've attached the library. I\ve downloaded it from here http://www.agentpp.com/snmp_pp3_x/snmp_pp3_x.html . 

Thank you very much in advance.
