Prevent CMP0116 warning with CMake 3.20 or later

CMake 3.20 introduced a change in the handling of relative paths in *.d
depfiles referenced by custom commands. To avoid a CMP0116 policy
warning, we have to explicitly set the policy to NEW and also change
the relative path(s) we embed in the depfiles to be relative to
CMAKE_CURRENT_BINARY_DIR rather than the top level binary directory.
