Makefile help

Hi there!

I have two directories: source_dir and dest_dir. In the directory 
source_dir I have number of sub-directories and files. My goal is:

1.Recreate the sub-directory structure of the source_dir inside of the 
dest_dir

2. Each file found in source_dir should be converted to a new format 
using some command CMD in the following way:
CMD source_dir/<path to file>/<file name>.src dest_dir/<path to 
file>/<file name>.dst

So, if source_dir contains:

source_dir
  +sub1
  |  +file1.src
  |  +file2.src
  |
  +file3.src
  +file4.src

In the dest_dir I would like to obtain:

dest_dir
  +sub1
  |  +file1.dst
  |  +file2.dst
  |
  +file3.dst
  +file4.dst

Is it possible to do it using make in a fully automatic way? What I mean 
is that make should find all sub-directories and files in source_dir by 
itself. Note that the sub-directories level may be grater than 1, no 
symlinks allowed.

I do not have experience in writing Makefiles. Appropriate Makefile 
examples appreciated.
