Could not find compiler set in environment variable CUDACXX

[Arthur-Ling]

When I run "bash build_cutlass.sh", an error happens:

-- CMake Version: 3.18.2
-- The CXX compiler identification is GNU 8.4.1
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done

what should I do before "bash build_cutlass.sh"?

1. you should check the path /usr/local/cuda/bin/nvcc, maybe the path not exist;
2. then find the nvcc path, My path is /root/miniconda3/bin/nvcc
3. modified the build_cutlass.sh file, like this
   #export CUDACXX=/usr/local/cuda/bin/nvcc
   export CUDACXX=/root/miniconda3/bin/nvcc

then it will work

@DonliFly Hi，How can I find the path to nvcc?
