windows install error: isfile(__libcupti[])

I get the following on a fresh install on a windows machine.

julia> CUDA.device()

After I copied cupti to the correct name, it started giving similar errors on other libraries.

I checked out the dev version. This time I got:

Dup of #300, fixed on master

You need to use the Manifest, or check-out (currently) GPUArrays from master too.
