Cadabra author here. On Unix, the Cadabra build/install process
installs a Jupyter kernel, which works with SageMath installed
from the binary distribution (may need some PYTHONPATH setting,
but nothing more). On Windows, the build process using Visual
Studio is relatively simple, but getting everything to see all
required libraries is a never-ending horror story. Maybe someone
on the SageMath team responsible for the Windows port can help
out; I have no resources to properly support Windows.
The alternative is to run the lot in WSL and then install a
binary distribution of Cadabra; that is known to work from
first-hand experience using a non-SageMath Jupyter installation,
but I have no doubt it can be made to work with the one supplied
by SageMath. You can still connect to the Jupyter kernel from
your Windows browser that way.

I'm able to build Cadabra2 in SageMath environment (at sage
--buildsh
prompt, that is)
on Debian Linux. This way it should be possible to use it
with Sage's
Jupyter notebook.
But on Windows, well, probably much harder...

I just want to use Cadabra2 in the Jupyter Notebook provided
by the SageMath installation and may be with minimal
installation of some software.
