[cmake-developers] Makefile copy constructor

[Andy Cedilnik]

Hello,

Well, I use makefile for all the internals of CPack, such as parsing of 
files, storing variables, configuring files, etc.

Since I cannot reuse Makefile without having lots of junk left from the 
old one, what I do is create a copy of it for each generator.

So, something like this:

* Create Makefile
* Parse command line arguments
* Parse config file
* Overwrite config values with command line arguments
* For each generator:
  * Copy makefiles
  * Create generator based on makefile
  * Run generator

Currently the only thing I really need is the map of variables, but in 
the future, I will also need macros, commands, etc.
