Should Netbeans see libraries without specifying include path?

In Arch, should Netbeans be able to see libraries like GTKmm by default?
I included gtkmm.h but for Netbeans to find it I have to include /usr/include/gtkmm-whatever
Then I have to include all the dependencies for gtkmm (which is a lot)

Is there a way where it will know all the library include paths?
