Summary:                    CUDA separable compilation intermediate file doesn't
get created
Description: 
When I compile with CUDA_SEPARABLE_COMPILATION=TRUE the custom command for the
generation of the intermediate_link.obj does not get triggered. When I change
line 1590 in FindCUDA.cmake (master version from earlier today) to
`set(do_obj_build_rule TRUE)` the custom command does run and compilation
succeeds. I don't see the bug here.

I'm seeing this behavior with cmake 3.2.2 and master revision 17ecfd8210.

Steps to Reproduce: 
configure a cuda library target with CUDA_SEPARABLE_COMPILATION=TRUE and build.

Additional Information: 
This is with cuda toolkit 7.0

I must have made a mistake earlier. I cannot reproduce this with master anymore.
Sorry for the bother.

Turns out I wasn't able to reproduce the issue because I switched compilers to
VS2012 and VS2010. But when I went back to VS 2013 the problem is reproducible.

It appears that the workaround for the object build rules used for VS2010 and
VS2012 does not work for VS2013. Apparently the multilevel object dependency
problem has been fixed in VS2013. The attached patch solves the problem for me.

I wasn't able to reproduce this earlier.
