How to read/load  the cmake file in python and access its elements.  
I have a scenario, where i need to load the make file and access its elements.  
I have tried reading the make file as text file and parsing it,but its not the ideal solution

What do you mean by “elements” of a make file? Is that a term with a
specific meaning, or do you mean some particular parts of the make file?

You might be interested in using a library purpose-built for creating a
parser <URL:http://pyparsing.wikispaces.com/>.

I'm not aware of any makefile-syntax-aware tool for Python. Your best
option could be to write your own parser using the above library.

First, just what do you mean by "make file"?  You refer to cmake, make, 
and .mk in three places in your message.  How about a link to the actual 
tool you're interested in? And a brief list of the other tools you're 
using it with.

Is this it?
http://www.cmake.org/

Once we're talking about the same tool, then the question is what 
"elements" are you interested in?  If your cmake is anything like the 
traditional make program, the format is deceptively simple, and 
enormously complex in usage.

But I suspect that your cmake has very little to do with Unix make 
tools.  The cmake that I gave the link for uses a CMakeLists file, which 
looks nothing like a makefile.

Take a look at pymake:

"make.py (and the pymake modules that support it) are an implementation 
of the make tool which are mostly compatible with makefiles written for 
GNU make."

http://hg.mozilla.org/users/bsmedberg_mozilla.com/pymake/

There is a parser.py file which might be useful to you.
