Have you looked at the manual?

Check here, for one place:

http://www.gnu.org/software/make/manual/make.html#File-Name-Functions

You can always do something like:

SRC1 := ./somdir/*.cc

And then use text functions on the list.

See here for some discussions on installation:

http://www.gnu.org/software/make/manual/make.html#Install-Command-Categories

One way to "store" files by type in different directories is with
special targets:

store_obj:
<tab> mv $(OBJ) $(OBJ_STO_DIR)

Or use the file/text functions to manipulate the desired directory in
your build targets.

Lots of ways to things.  There are many examples of Makefiles on
sourceforge.net and gcc.org  There is also the book from O'Reilly:
