REVISION SUMMARY
  simply sets a variable when the source is under version control. use it to
  auto-enable Debug builds. there are also plans to switch special assertion
  logic on in KIO when used from git, so there definitely is a more generic
  use case of wanting to control behavior based on whether it the source is
  likely used to make a development or production build.
  
  conceivably the module could be used in the future to get git rev-parse or
  the like, hence the generic name.

TEST PLAN
  with .git the var is true, without it is false

  R240 Extra CMake Modules
