Using python=3.12 succeeds

[deGravity]

I am now realizing that there is no 3.13 release on pypi, so this may simply be a build problem.

[alecjacobson]

Please try the dev version.

For some reason I thought that 3.13 would pick up the 3.12 version. But I could be mistaken.

[pielet]

dev version works

pip install libigl==2.5.4.dev0

[alecjacobson]

the 3.12 version doesn't seem to work on intel mac with 3.13 so I'm trying to compile binaries properly #268
