How can I give the sourcefilepaths to gcc? - c

Question

How can I give my sourcepaths to gcc?
I have my .c files in source and test directory.
How can I give gcc the path to it? Im compiling with amakefile` and always get the message
"no such file or directory test.c"
My directory structure:
make-directory|
|
|--source
|
|--Header
|
|--test
|
|--out
|
as asked:
# makefile to generate UNIT-tests
# define any directories containing header files other than /usr/include
# TODO

CUnit/sources/Automated \
CUnit/sources/Basic \

# For each word in 'name' replace 'string1' with 'string2'
#OBJ = $(SRCS:%.c=%.o)
OBJ = $(TST_SRCS:%.c=%.o)
#OBJ=$(join ($(SOURCES)), $(notdir $(SRCS:%.c=%.o)))
# define the C compiler to use
CC = gcc
# define any compile-time flags
CFLAGS = -O0 -g -Wall -fmessage-length=0 -fprofile-arcs -ftest-coverage
#TODO Linkerflags

VPATH=source
# define the executable file,

all:

You can make use of vpath or VPATH in makefile to point to the directory containing the source files.
See the online gnu make manual here.
