[cmake-developers] [patch] FindIce updates

[Roger Leigh]

I have opened a couple of merge requests here, and also merged these 
into next for testing:

https://gitlab.kitware.com/cmake/cmake/merge_requests/17
https://gitlab.kitware.com/cmake/cmake/merge_requests/19

The first adds support for the latest 3.6.x releases.
The second adds support for finding debug variants of the library, uses 
SelectLibraryConfigurations and adds support for release and debug 
variants to the imported targets.


Regards,
Roger
