Update the deprecated property and fix the empty value on macOS

The `IMPORTED_LINK_INTERFACE_LIBRARIES` is deprecated and is
updated to `INTERFACE_LINK_LIBRARIES` instead.
On macOS `CMAKE_THREAD_LIBS_INIT` is empty since empty the thread
functions are provided by the system libraries. To avoid getting
`set_target_properties called with incorrect number of arguments` error
message, we put it inside double quotes.
