CodeLite IDE

I'm trying to add "pugixml library" for XML support to my project. I've downloaded files from their site but I couldn't figure out how do I add them to my project. It doesn't have include directory. It has src, scripts and docs files in it. I have downloaded pugixml library from this web site:
https://pugixml.org/

It seems more a question for pugixml library.

In Codelite,
in project option:

• In compiler option, you have to add appropriate include path in "IncludePath"
• in linker option, you have to fill "Libraries" and "Libraries Search path"
