General discussion • Multiple source files in a makefile

I am working with a display interface that comes with a pre-configured makefile, that adds their code to your C code. I got it working with adding additional include files to work, but nothing I have tried has allowed me to add additional C files. Here is the make-file I need to work with:

#####################################################################
#
# This file compiles a single .c or c++ file (with the base-name
# defined by TARGET) as well as any additional files specified by
# ADD_FILES. Edit TARGET and ADD_FILES variables as needed.
#
# This file must be edited by adjusting directory path as well as
# un-commenting additional options depending on the platform.
# By default, Linux options are used.
#
# Edit the GLG_LIB line to use either GLG EVALUATION or PRODUCT
# libraries.
######################################################################

# Default compiler
CC = gcc
#CC = g++
# Place any additional compiler options here.
OPTS = -g

######################################################################
# Uncomment one of the GLG_EXT_LIB lines for linking with either the
# intermediate or extended library in addition to the GLG Standard API.
# For C++, also uncomment a corresponding GLG_CPP_API_OPTS option below.
######################################################################\

# Linking with the GLG Intermediate API.
#GLG_EXT_LIB = -lglg_int
# Linking with the GLG Extended API.
GLG_EXT_LIB = -lglg_ext

####################################################################
#
# For C++ compiling, uncomment one of the GLG_CPP_API_OPTS lines
# to match the GLG library used for linking (Standard, Intermediate or
# Extended).
#####################################################################
\#
#GLG_CPP_API_OPTS = -DGLG_CPP_INTERMEDIATE_API
#GLG_CPP_API_OPTS = -DGLG_CPP_STANDARD_API
GLG_CPP_API_OPTS = -DGLG_CPP_EXTENDED_API

#####################################################################
#
# Uncomment one of the GLG_MAP_LIBS lines for linking with or without
# a map server.
######################################################################

# Linking without map server.
GLG_MAP_LIBS = -lglg_map_stub

# Linking with the map server.
#GLG_MAP_LIBS = -lglg_map -ltiff

#####################################################################
#
# Uncomment OPENGL_LIBS line for linking with OpenGL libraries
# if the application uses OpenGL outside of the GLG drawing.
#####################################################################
#
#OPENGL_LIBS=-lGLU -lGL

# Uncomment one GLG_LIB line for linking with the GLG evaluation,
# product or Community Edition libraries.
######################################################################

# To use GLG EVALUATION libraries
#GLG_LIB=-L$(GLG_DIR)/eval/lib

# To use GLG PRODUCT or COMMUNITY EDITION libraries
GLG_LIB=-L$(GLG_DIR)/lib

# On Linux, uncomment the line below for additional libraries.
# Due to a known bug in ldd/dlopen, -lpthread is required to avoid a crash
# when OpenGL is used.
EXTRA_LIBS = -lpthread

# On Solaris, uncomment the next line for additional libraries\
\
#EXTRA_LIBS = -lnsl -lsocket
# On AIX, uncomment the next line for additional libraries
#EXTRA_LIBS = -liconv

# To use static Motif library (libXm.a), uncomment the next line for
# additional libraries

# Name of the main file to compile and link
# (without the .c or .cpp extension)

# Uncomment to list additional files here (.o)
