In the cmMakefileTargetGenerator you can test for the option with

  this->Makefile->IsOn("...")

Probably like CMAKE_VERBOSE_MAKEFILE which is another option to the
Makefile generator.  See CMakeGenericSystem.cmake.  Surround it by

  if("${CMAKE_GENERATOR}" MATCHES "Make")
     ...
  endif()

so that it only shows up for Makefile generators.
