As far as my knowledge goes '$< ' will automatically search the mentioned
source file in the folder mentioned by SRC .for example in this case
a1.o:a1.c
$(CC) -$INCLUDE -$(CFLAGS) -I. -I$(SRC) -c $<
'$<' will automatically search the source file in the path mentioned by
SRC(/Module/src) macro.
i.e.above thing will automatically search source file a1.c in /Module/src/
Module1/a1.c
No. "-I" is tells the _gcc_compiler_ where to look for "include"-files.
The Make program does not account for this, it cannot know.
There are ways to supply search paths for _make_ , but you will
have to read a lot of documentation, writing makefiles is a mastery
of itself. You may read

P.S.
By the way, the lines of the form
" $(CC) -$INCLUDE -$(CFLAGS) -I. -I$(SRC) -c $<"
are redundant, make generates these calls by itself.
