Marc Chevrier 4248bb452a CUDA: Device linking use now link options
properties LINK_OPTIONS and INTERFACE_LINK_OPTIONS are propagated
to the device link step.

To control which options are selected for normal link and device link steps,
the $<DEVICE_LINK> and $<HOST_LINK> generator expressions can be used.

When a device link step is involved, which is controlled by
:prop_tgt:`CUDA_SEPARABLE_COMPILATION` and
:prop_tgt:`CUDA_RESOLVE_DEVICE_SYMBOLS` properties, the raw options will be
delivered to the host and device link steps (wrapped in ``-Xcompiler`` or
equivalent for device link). Options wrapped with ``$<DEVICE_LINK:...>``
:manual:`generator expression <cmake-generator-expressions(7)>` will be used
only for the device link step. Options wrapped with ``$<HOST_LINK:...>``
:manual:`generator expression <cmake-generator-expressions(7)>` will be used
only for the host link step.
