You should configure Trilinos, build it, and install it into a separate
directory. This directory will contain the C++ headers and libraries
necessary for you to build the modified example. There are instructions for
doing this here:

I have attached a simple Makefile that I use when building an external
executable against an installed version of Epetra/Anasazi. You should be
able to modify this to your needs.

Bienvenue et bonne chance,
