There are in total 503 unresolved externals. I checked the first one, and find that is is present in the downloaded libxml2_a.lib, but without the underscore. The directories of the downloaded libraries are correctly added to the compiler command line.
It might help to see the command line.
I have now figured out what I did wrong. I have both VS 2019 and VS 2022 installed. If I don't do anything, setuptools selects the latter, and that doesn't match the compiler the external libs are compiled with (and, presumably, Python itself). So, I searched for a batch file to make setuptools use the correct compiler, and chose the wrong one, apparently. Adding some debug statements to msvc.py taught me that I need to call this batch file before starting the build: "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" (with a x86_amd64 parameter). After that, everything works as expected. Kind regards, Gertjan.
