Makefile help please :-(

Hi All...

I am trying to create a makefile for a project. I run Arduino 1.0 on Windows. I found a makefile here:

And have been modifying it. At this point, it can successfully build a simple sketch that has one source module and emit a HEX file. So far so good. Then it gets dicy. My project has a bunch of files, and it can't seem to find the include files. As I understand it, this file emulates the Arduino environment by generating a main.cpp file in an applet subdirectory, then compiles that cpp file. That's fine for now, although later I'll want to modify that behavior by providing my own main.cpp. This is because when it concatenates the cpp files, the compiler gives me warnings and errors at line numbers that are wrong.

Anyhow, I have tried modifying the makefile to add -I. and -I.. to the lines that specify where to search for includers. No luck. The first few errors are:

applet/main.cpp:6:23: error: constants.h: No such file or directory
applet/main.cpp:14:17: error: I2C.h: No such file or directory
applet/main.cpp:18:19: error: SdFat.h: No such file or directory
applet/main.cpp:19:40: error: SdFatUtil.h: No such file or directory
applet/main.cpp:37:94: error: Bounce.h: No such file or directory

Here is the make file:
