CMake Warning (dev) at Dashboards/Scripts/Possibly_Run_Dashboard.cmake:14 (include):
  Policy CMP0011 is not set: Included scripts do automatic cmake_policy PUSH
  and POP.  Run "cmake --help-policy CMP0011" for policy details.  Use the
  cmake_policy command to set the policy and suppress this warning.

  The included script

    /home/dashboard/Dashboards/Scripts/Run_Dashboard.cmake

  affects policy settings.  CMake is implying the NO_POLICY_SCOPE option for
  compatibility, so the effects are applied to the including context.
Call Stack (most recent call first):
  Dashboards/Scripts/GenericFunctions.cmake:77 (include)
  Dashboards/Scripts/Call_process_dashboard.cmake:11 (process_dashboard)
  Dashboards/Scripts/GenericFunctions.cmake:19 (include)
  Dashboards/Scripts/AutoStart.cmake:21 (do_all)
This warning is for project developers.  Use -Wno-dev to suppress it.
