hipConfig.cmake issue on NVIDIA about hipblas HOT 6 CLOSED

While building on NVIDIA, hipBLAS searches for CUDA_cublas_device_LIBRARY path and fails on ubuntu 18.04 with cuda-10.1

@amcamd #54 should fix this. Let me know if there are any issues

from hipblas.

@amcamd this is fixed on @NEELMCW fork but not merged yet.

I also have this problem. @NEELMCW 's branch fixes the issue with hipBLAS trying to select hcc backend all the time, it still gives the error

However, I found out the problem, it is a CMake versioning problem. I was using CMake 3.10, and I switch to 3.12.4, and the problem went away. It now compiles hipBLAS correctly

from hipblas.

I still have this problem even with cmake 3.15.3. @NEELMCW fork works fine.

from hipblas.

I am also encountering the problems reported here. The alternatives are either to install all hip_hcc stack, although that is unneeded with a nvcc backend (and heavy for containers), or using @NEELMCW's fork.
