I need MPI support along with GPU (GeForce GTX 1080 Ti, CUDA driver version is 11.4 and running version is 10.1) for which I have to build qiskit-aer from source. My python version is 3.8.16. I have done installing all requirements mentioned in CONTRIBUTING.md. However running final command with required options;
python3 ./setup.py bdist_wheel -- -DAER_THRUST_BACKEND=CUDA -DAER_MPI=True
I am getting following Error which I am unable to resolve.
