Sorry, I spoke too soon. It should not be needed, but something fails
in the process of building the sirocco cython extension module
(when built in the classical non-meson way, which is still the default)

ImportError:

undefined symbol: homotopyPath_mp_comps
Indeed, as I see, it's not linked against libsirocco (in local/lib) -
even though the latter is built.

A quick way to fix it might be to add a pkg-config .pc file to
facilitate its discovery
(at least a similar spkg, braiding, works for me, as it has the latter in place)
