file: GLOB with CONFIGURE_DEPENDS, VerifyGlobs.cmake, and symlinks

i'm running into an issue with glob(... CONFIGURE_DEPENDS ) ... if there are symbolic links matching the glob expression, i'm ending up in a configure-loop:

[0/2 ?/sec] Re-checking globbed directories...
CMake Warning (dev) at CMakeFiles/VerifyGlobs.cmake:13526 (file):
  Policy CMP0009 is not set: FILE GLOB_RECURSE calls should not follow
  symlinks by default.  Run "cmake --help-policy CMP0009" for policy details.
  Use the cmake_policy command to set the policy and suppress this warning.
This warning is for project developers.  Use -Wno-dev to suppress it.

-- GLOB mismatch!

afaict cmake is called recursibely, but CMP0009 is not set in VerifyGlobs.cmake, nor propagated when i set the policy in my CMakeLists.txt file
