[cmake-developers] Adding backtraces to every command

Hi Rich,

FYI there is discussion about providing backtraces from the server
to clients here:

  https://gitlab.kitware.com/cmake/cmake/issues/17539

It was originally done in CMake 3.10.0 but caused major memory bloat
and so was reverted.

Threading that through everywhere for arbitrary properties will cause
too much memory usage.  `cmTargetInternals` already has dedicated
fields for backtraces of specific properties.  Something like that
could be added for the properties you need.

Can you provide more details about the use case?
