[Ctk-developers] CTK license and copyright

Hi Jc,

A CMake module sounds like a wonderful idea. I will put it somewhere
high on my Debian todo list. For me this is a good chance to learn
more about the internals of CMake.

FYI, For Debian packages it is not necessary that every file contains
a license if there is a README file which clarifies the
license/copyright situation for the whole project. For example think
about .cmake files, only few people add a license to those files, but
they are still covered by the 'main' license.

Cheers
Dominique
