Please visit http://archive.ambermd.org/202011/0157.html. This solution
is untested (at least by me), but stands a good chance of working.

Note the the highest CUDA version in unpatched code is 11.0, not 10.2.

I'm rather surprised that the default CUDA is 11.2, since that was
released only about a week ago, and explains why no Amber developer has
tested it yet.
