cyipopt fails to compile with Python 3.13

[moorepants]

This works:

$ conda create -n cyipopt-pip numpy setuptools cython ipopt pkg-config pip python=3.12  # install all build and run deps
$ conda activate cyipopt-pip
$ python -m pip install --no-deps --no-build-isolation cyipopt

but this fails:

$ conda create -n cyipopt-pip numpy setuptools cython ipopt pkg-config pip python=3.13  # install all build and run deps
$ conda activate cyipopt-pip
$ python -m pip install --no-deps --no-build-isolation cyipopt

Error in compilation seems to be:

cyipopt/cython/ipopt_wrapper.c:26966:69: error: unknown type name ‘__pyx_vectorcallfunc’; did you mean ‘vectorcallfunc’?

See the full log in #284 (comment)

[moorepants]

Same error seen here: scipy/scipy#21275 which seems to indicate a numpy version mistmatch being downloaded.

I just tried it again with Python 3.13 and it worked. Not sure why:

moorepants@nandi:cyipopt(master)$ conda create -n cyipopt-pip numpy setuptools cython ipopt pkg-config pip python=3.13
