cmake: set CMP0075 to NEW (for ws2_32.lib in win32)

Otherwise cmake complains:
  Policy CMP0075 is not set: Include file check macros honor
  CMAKE_REQUIRED_LIBRARIES.  Run "cmake --help-policy CMP0075" for policy
  details.  Use the cmake_policy command to set the policy and suppress this
  warning.

  CMAKE_REQUIRED_LIBRARIES is set to:
    ws2_32.lib

  For compatibility with CMake 3.11 and below this check is ignoring it.

(cherry picked from commit 6d3a53966bc822fd580a6a02301838aca601391b)
