Setting up MAKE file for Postgres and C++/Newbie question

I've found, compiled and tested the libpq++ c++ program examples.  I've even
modified them to work with my database.  Now I want to take an existing
program written in c++ and add the postgres classes.  I also want to do this
in my working directory, not the samples directory.  The make file with the
examples is pretty intense.  Does anyone have a simpler version that will
set the appropriate paths for the includes?  I naturally want to use the
header files included with postgres, not copy them around.
