Karl,

good question. The docs say that you supply OPTIONS to cuda_add_library, 
which are in turn handed over to cuda_wrap_srcs. the only chance I see 
is digging there. internally, both cuda_add_xxx create regular cmake 
targets.

I am not sure why cmake doesn't accept subsequent set_target_properties 
calls on them. I cannot spare the time resources to dive into this 
further. Sorry! Maybe it's worthwhile to file a bug report and bring 
that to the attention of the FindCUDA.cmake author?

Best,
peter
