Subject: [PATCH] COMP: Set CMP0074 to NEW

To address in the ITKExamples Superbuild:

  CMake Warning (dev) at Modules/ThirdParty/VNL/src/vxl/config/cmake/Modules/FindZLIB.cmake:20 (find_package):

  Policy CMP0074 is not set: find_package uses <PackageName>_ROOT variables.
  Run "cmake --help-policy CMP0074" for policy details.  Use the cmake_policy
  command to set the policy and suppress this warning.

  CMake variable ZLIB_ROOT is set to:

    /.../ITKEx-bld/zlib-install

  For compatibility, CMake is ignoring the variable.
