I would like to suggest that the next version of Code::Blocks have the provision to create NANA C++ project.

it would be better you post this on the sf bug tracker. Here in the forum it will get lost...
It is best to post a template script as a patch in the tracker.
I doubt anyone from the dev team will spend time to write a template for library he/she is not using.
You already asked this question here NANA C++ projects (http://forums.next.codeblocks.org/index.php/topic,22085.msg150297.html#msg150297), since no devs are using this library, so we need some users help to create a project wizard.
Please do not post the same topic twice!
You already got a meaningful answer in the first topic.
I merged the threads.
