[CMake] Cuda CUDA_SEPARABLE_COMPILATION errors during linking

[Wesley Smith]

With CUDA_SEPARABLE_COMPILATION enabled, I'm always getting linking
errors when I try to build.  Seems it's looking for a directory that
doesn't exist:
'<snip>/build/CMakeFiles/SlicerLib.dir/Debug

If I manually create this directory, everything works.  Seems that
either the directory path isn't being computed properly or that code
to create the directory if needed is missing.
