Summary:                    RFE: Report changes to cached values
Description: 
Add a variable to CMake such that it will report when a cached variable's value
is different from the default being set. For example:

    set(var dflt CACHE STRING "description")

could output:

    path/to/CMakeLists.txt:42: var 'dflt' -> 'cachedvalue'

and could also, at the end of configure, print out a command line (or initial
cache file) to be used to duplicate the build on another machine. I was thinking
of 'CMAKE_REPORT_DELTA' as the control variable.

Came up from a gn thread:
