AFAIUI, the "pcsc-lite header files" is the single file
/usr/include/PCSC/winscard.h, which is rather short. Since the
implemented PCSC API is rather stable I think we ship a copy of that
file as patch in the wpa_supplicant package.

Yes, this is the branch that ubuntu (and debian, btw) is shipping atm.
thanks for your feedback on this!
