[CMake] INTERFACE_LINK_LIBRARIES/LINK_INTERFACE_LIBRARIES

[Hendrik Greving]

In other words, when providing the EXPORT_LINK_INTERFACE_LIBRARIES flag for
exported targets (in main project that was changed to CMP0022 NEW), I was
expecting the IMPORTED_LINK_INTERFACE_LIBRARIES property set in the
<exported_target>.cmake file so that projects that import it (with CMP0022
OLD) can see it. Instead, I am only seeing the INTERFACE_LINK_LIBRARIES
property set.
