[Fedora-packaging] cmake rpm macro(s):

[Rex Dieter]

Appended is a first try at rpm macro'izing the the call to cmake per:
http://fedoraproject.org/wiki/PackagingDrafts/cmake

I chose not to implement the out-of-tree style of build in the 
PackagingDraft to keep things simple(r).

Made each cmake option a separate macro to make in easier to override.

Comments?
