read in files from ipopt bin folder

[philsuess]

Hello,

thank you for this project.

This change is rather small: it does not assume to know the folder contents of the ipopt bin folder, but reads them out. When using this with the latest release from the ipopt github repo, this is what is printed out:

Found ipopt binaries ['coinmumps-3.dll', 'ipopt-3.dll', 'ipoptamplinterface-3.dll', 'libifcoremd.dll', 'libiomp5md.dll', 'libmmd.dll', 'sipopt-3.dll', 'svml_dispmd.dll'].

Let me know if this is helpful.

Best,

Phil

This is potentially helpful, but we currently support a range of IPOPT versions, so I needs to work with that range. Have you tested with the older versions?

I tested it with the one specified in the setup.py (line 145): https://github.com/coin-or/Ipopt/releases/download/releases%2F3.13.2/Ipopt-3.13.2-win64-msvs2019-md.zip

and the latest one: https://github.com/coin-or/Ipopt/releases/download/releases%2F3.14.17/Ipopt-3.14.17-win64-msvs2022-md.zip

The failure seems to be unrelated (something like a corrupt package):

Mind, when I say that I have tested it, I mean that the pip install . goes through successfully. However, I still can't get over the error

cyipopt\__init__.py:12: in <module>
    from ipopt_wrapper import *
E   ImportError: DLL load failed while importing ipopt_wrapper: The specified module could not be found.

I am sure that this error is unrelated to my changes - I get the same error when I run pytest on this repo (without my changes). That's another problem, however. Just want to state my full disclosure :)

The "Manually install on Windows" CI runs shows:

Run python setup.py install
Using Ipopt adjacent to setup.py in D:\a\cyipopt\cyipopt on Windows.
Found ipopt binaries ['ipopt-3.dll', 'ipoptamplinterface-3.dll', 'libifcoremd.dll', 'libmmd.dll', 'msvcp140.dll', 'svml_dispmd.dll', 'vcruntime140.dll']
running install

And it successfully solves the example problem, so I the change should be suitable.

Thanks!
