[petsc-users] Combining SUPERLU_DIST with CUDA fails

[Roland Richter]

In that case it fails with

/~/Downloads/git-files/petsc/mpich-complex-linux-gcc-demo/externalpackages/git.superlu_dist/SRC/cublas_utils.h:22:10:
fatal error: cublas_v2.h: No such file or directory/

even though this header is available. I assume some header paths are not
set correctly?

Thanks,

regards,

Roland
