Answer 1

That package is for C++ kernel support in Jupyter. More idiomatic for Jupyter + Conda is to keep Jupyter and each kernel in separate environments.

Jupyter Environment

conda create -n jupyter jupyter nb_conda_kernels

C++ Kernel

conda create -n xeus xeus-cling

In this setup, one would always launch Jupyter from the activated jupyter environment, then select the xeus kernel for the notebook.

conda activate jupyter
jupyter notebook
