[CMake] cmake project patterns / examples

[Adam]

Thanks for the comments I've update the wiki. Top-level only now marked as
anti-pattern
https://github.com/toomuchatonce/cmake-examples/wiki/cmake-patterns-and-examples

If there are other patterns / anti-patterns you've seen please send me a
pull request and I'll add them.

I'm particularly interested in super-build patterns that allow sub-projects
(for both inhouse and 3rdparty components) to be shared between projects.
