We do and it should indeed work for the tests. Setting an environment variable 
should be reasonably low burden if/when default path is not good enough.

PATH does suffer from the problem that ptxas location is not necessarily the 
right CUDA location. I.e. sometimes it's found via /usr/bin which I can not 
drop from the PATH, so one should be careful to *prepend* desired ptxas 
location.
