How to include external library netbeans?

[Vincy6]

I need to use the curl library in my C++ project. I'm using Netbeans installed on Window 7.

I' ve downloaded the library. I think that I have to say to the editor which are the folder, but how?

And how can I add other library? I need ho use also the regex lib!

Thank's for any help and sorry for my english!
