Tim,
I always build on Jessie and haven't run in any FTBFS due to CMP0046 (at 
least until last Saturday). Nevertheless looking at some log files I can 
see warnings about that.
We can push a patch similar to the one pushed in commit 0d5ca8be for 
CMP0026. But given the reasons of such warning:

"Error on non-existent dependency in add_dependencies.
CMake 2.8.12 and lower silently ignored non-existent dependencies listed 
in the add_dependencies() command.
The OLD behavior for this policy is to silently ignore non-existent 
dependencies. The NEW behavior for this policy is to report an error if 
non-existent dependencies are listed in the add_dependencies() command."

IMO it would be better to remove or fix the non-existent dependency.

Perhaps we can push a patch temporarily for v14.0.0 and file a bug 
report against fixing all non-existent dependencies for after v14.0.0.

What do you think?

Cheers
