build
URL: https://github.com/apache/singa/pull/624#issuecomment-598734929
 
 
   I simplified the selection logic to use only one environment variable CUDA:
   1. export CUDA = 9.0, then use CUDA9.0 without nccl and moich
   2. export CUDA = 10.0, then use CUDA10.0 without nccl and mpich
   3. export CUDA = DIST, then use CUDA10.0 WITH nccl and mpich
   4. without export CUDA, then use CPU only
   
   If we need two environment variables (CUDA and DIST) to determine the selection logic,
I can change it.
