Optional packages in conda

[mmarco]

Now that the recommended way to install sage is through conda (which makes it way easy that compiling from source), I am having the problem with installing optional packages.

Some (like sirocco)  are already in conda-forge, so it is easy to install them, but in particular, I am being unable to install Tides and Kenzo.

Which should be the way to install them? Should we create packages in conda forge for them?

Yes, having them in conda-forge is the recommended way.

How is the process to add a package to conda-forge?

Also, it might require changes in sage, to look for the corresponding files in the right place

See https://github.com/conda-forge/staged-recipes/#getting-started for some instructions.

You can also ask your favourite AI model to give you the code for it.

if one uses sage the distro, it will also need adding spkg-configure.m4 files.
But that's the only needed change, as these packages are not requiring
any extension modules,
and are loaded anyway, with runtime detection of their availability.

I meant that, for example, kenzo looks at the variable KENZO_FAS, which I think is not properly set when you install sage in conda-forge.  Tides depends on SAGE_LOCAL, which again, is not set in the conda-forge install. Would adding skpg-configure.m4 be enough to handle this?
