CodeCoverage: causes a cmake warning when used with googletest.

[CiaranWelsh]

My project builds fine but when I include CodeCoverage.cmake I get warnings issued from googletest.

set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake)
include(CodeCoverage)

Causes the warning to be issued:

CMake Warning (dev) in third_party/googletest/googletest/CMakeLists.txt:
  Policy CMP0022 is not set: INTERFACE_LINK_LIBRARIES defines the link
  interface.  Run "cmake --help-policy CMP0022" for policy details.  Use the
  cmake_policy command to set the policy and suppress this warning.

  Target "gtest" has an INTERFACE_LINK_LIBRARIES property which differs from
  its LINK_INTERFACE_LIBRARIES properties.

  INTERFACE_LINK_LIBRARIES:

    gcov;Threads::Threads

  LINK_INTERFACE_LIBRARIES:

    Threads::Threads

Any idea how to resolve this without setting a CMake policy? Thanks.
