Original issue: https://charm.cs.illinois.edu/redmine/issues/966

./build charm++ gni-crayxe smp cuda

module load cudatoolkit fixes this but we should bail out very early if we can't find nvcc This is a longstanding problem in gpuManager Probably related to some other fixes/bugs

Same thing happens on NCSA nano cluster when no CUDA toolkit directory exists. Modified build script to bail out as soon as no CUDA toolkit is found. [[~~https://charm.cs.illinois.edu/gerrit/#/c/2150/~~ https://github.com/UIUC-PPL/charm/commit/632d3a98d54da02a4a64975cda662339df2d1b6f]]
