You could try two things:
1. Do what the error message suggests: add the following line to your
run_cmake script:
-DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-11.3
2. Running a Google search on "cmake could not find cuda" leads to the
following top hit:
https://stackoverflow.com/questions/19980412/how-to-let-cmake-find-cuda
This suggests several alternatives to solution 1:
a. set the CUDA_BIN_PATH environement variable (not CUDA_HOME -- that's
our fault)
b. make sure that nvcc is in your PATH (not sure why this didn't work
for you, but double-check that "which nvcc" gives what you want)
c. make a symlink from /usr/local/cuda-11.3 to /usr/local/cuda; check
that there is *not* symlink between /usr/local/cuda and any other
version of the CUDA toolkit
...good luck...dac
