Closes #2780
Note that upstream Python issue python/cpython#101614 means linking against
python3_d.dll
is useless, so I've set this to always use the version-specific builds for now.The heuristic for detecting a Windows debug build is... not great. I check if the
EXT_SUFFIX
starts with_d.
, which is the only thing that I could see in the sysconfig which suggested a debug build. If this proves to be brittle, we may wish to ask upstream for something better to be added tosysconfig
.
