I use nvcc to compile each .cu to a .cpp file as follows:
nvcc -I"MATLABROOT/extern/include" --cuda file.cu --output-file temp_a34b7.cpp
(Replace MATLABROOT, file.cu and temp_a34b7.cpp with the correct thing for you.) I then use mex to compile the .cpp files, making sure to include the relevant libraries (and their paths). It works for me (with cuda 2.3 on both linux and Windows), but I haven't tried it extensively.

HTH,
Oliver

I'm running into the same issues -- did you happen to try naming the
ARCH as AMD64 anywhere?

I'm putzing through this, so I'll document a bit:

need to change line 156 to:
($main::matlabroot = $main::cmd_name) =~ s%\\bin\\nvmex.pl$%%;

Now, my error is:
nvcc fatal : Cannot find compiler 'cl.exe' in PATH
