 We will now install the dependencies needed to compile xeux-cpp from source within this environment by executing the following
 ```bash
-mamba install notebook cmake cxx-compiler xeus-zmq nlohmann_json=3.11.3 jupyterlab CppInterOp cpp-argparse"<3.1" pugixml doctest -c conda-forge

 Now you can compile the kernel from the source by executing (replace `$CONDA_PREFIX` with a custom installation prefix if need be)
