[CMake] CUDA OBJECT libraries?

[James Bigler]

I looked at it briefly one day, and I couldn't figure out a way to tie the
output of custom commands to the list of objects that add_library(OBJECTS)
produces.

Alternatively since all you want is a list of objects, FindCUDA can produce
this just as well.

Use the CUDA_WRAP_SRCS macro.  It produces a list of object files from .cu
files.  You can use this list and link multiple libraries from the same
objects.  Look at the documentation for CUDA_WRAP_SRCS too see how to call
it.
