[CMake] Better support for "Windows Store App" projects

[Christian Oberholzer]

Hello all,

First off: This is my first time using a mailing list. So read a few posts
about using mailing lists. If I still do something wrong please apologize
and correct me! I will try to keep it short!

I noticed noticed that CMake has only little support for "Windows Store App"
projects. There are some bugs:
http://public.kitware.com/Bug/view.php?id=13749 (and additional numbers
0013511, 0013498, 0013749) in Mantis and there are two extensions
VS_WINRT_EXTENSIONS and VS_WINRT_REFERENCES. However both extensions are not
enough to get a new project up and running without importing a special
project.

Since I wanted to have it I pulled the source from the git repository and
implemented a first version which got me a Windows Store App project up and
running.

A few questions:
1) I would like to publish the patch. Can I just attach it here or is it
better to attach the patch to bug reports mentioned? And do I attach it just
as I normaly would or do I have to copy it into the mail content?
2) Once I uploaded the patch is there someone who can look at the patch and
point me into the correct direction to improve or fix any problems
3) I would like to discuss the implementation details. I am still open for
suggestions since I am not yet an experienced developer with Windows Store
Apps. But to have a patch which maybe could be added to CMake we should the
patch should be a solid implementation.

Thank you all,
Christian
