Answer 1

In my case I met both issues:

-lcurand not found

and

src/cpp/cuda.hpp:14:10: fatal error: cuda.h: No such file or directory

And exporting C_INCLUDE_PATH didn't helped me. Instead I needed to export general version of C_INCLUDE_PATH -- CPATH:

export CPATH=$CPATH:/usr/local/cuda/include
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/cuda/lib64
