llvm dev - Jun 2016 - ENABLE_TIMESTAMPS and update to CMake v3.5.2

I am in the middle of the fun and games of updating my out-of-tree sources
to the LLVM head revisions, and after updating to CMake v3.5.2 I am now
getting a warning that 'ENABLE_TIMESTAMPS' is being ignored.

 

Has support for embedding the timestamp in the build been removed or is
there a new way of configuring it?  I generally build internal transitional
builds with this enabled so that I can tell one build from another
reasonably easily, especially when the corresponding sources are not
committed and I can't use an SVN revision number to track it.

 

Thanks,

 

            MartinO

Okay thanks - I seem to have missed reading that discussion.

Hmm, but reading it now it seems that the issue is really whether it is on by
default, and not when explicitly selected (as I am doing).

It's not a big deal, just curious.
