Location of libcublas and libcudart

[girgink]

Describe the bug While compiling CHOLMOD it is assumed that libcublas.so and libcudart.so are located in the same directory, e.g. /usr/local/cuda-10.2/lib64. However, they might be located in different directories. In my case, which can be similar for other Debian/Ubuntu systems:

libcublas: /usr/lib/aarch64-linux-gnu/ libcudart: /usr/local/cuda-10.2/lib64

To Reproduce make install

Expected behavior Compilation should check LD_LIBRARY_PATH as well.

Desktop:

• OS: Ubuntu 20.04 (ARM v8.2, NVIDIA Jetson AGX)
• compiler gcc 9.3.0
• CUDA 10.2
• Version 5.6.0

I also have a non-standard installation of Cuda (11.0.2) I did not have any issue compiling. Here are my export :

# Using CUDA 11
CUDAPATH=/data/opt/cuda/cuda-11.0.2
export PATH="$CUDAPATH/bin:$PATH"

# Need this for the demo during the make
export LD_LIBRARY_PATH="$CUDAPATH/lib64:$LD_LIBRARY_PATH"

After that, just make config and I get :

----------------------------------------------------------------
SuiteSparse package compilation options:
----------------------------------------------------------------

SuiteSparse Version:      5.10.1
[...]
CUDA library:             CUDART_LIB=      /data/opt/cuda/cuda-11.0.2/lib64/libcudart.so
CUBLAS library:           CUBLAS_LIB=      /data/opt/cuda/cuda-11.0.2/lib64/libcublas.so
[...]

This should be fixed with the new CMake structure. SuiteSparse_config.mk is now gone entirely (yay!).
