List of dependencies from cmake

[Torgny Nyblom]

Hi,

as build.kde.org is moving to using kde-build-dependencies as a source for 
dependencies instead of the json/"put all else in one place" approach it has 
now I find my self in need of getting a complete list of dependences for each 
project.

If kde-build-dependencies had been updated (still not used I think) this would 
have been easy but now...

Can I do some cmake magic and get a list of dependencies for a project?

The plan is to use the above magic and get a list, that list should then be 
manually cleaned and the result put in kde-build-dependencies to avoid having 
to repeat the process later.

/Regards
Torgny
