> When I build arrow_python on Windows in debug mode it raises a link error "{{LNK1104: cannot open file 'python37_d.lib'".}}
> I have been having a look at the CMake files and it seems that we are forcing to link against release python lib on debug mode.
> I have edited the CMake files in order to fix this bug, see [^fix-msvc-link-python-debug.patch].
> It is just a 3 lines change and makes the debug version of arrow_python link on Windows.
> I could do a PR if you find it useful.
