Funny enough, it affects both #pip and #installer. Long story short, the include install path uses "distribution name", and in both cases the distribution name is apparently taken from the filename. Not sure if this is a bug or a feature, but I guess i'll file bugs. Installer even has a TODO item to determine whether they should be using original or normalized name.
Discussions on Python.org · Installing headers from wheel: should the directory be normalized or not?I’d like to discuss the correct behavior for installing headers (as in .h files) from wheels. What prompted me to do this is that the recent change in setuptools where wheel filenames started being normalized, domino-style broke installing PyCXX package, as headers started being installed into lowercase cxx directory rather than uppercase CXX as the reverse dependencies expect. Currently, the headers included in wheels are installed by tools to a directory roughly resembling: { sysconfig.get_...
