Delete several obsolete LCG find-modules
Delete the following obsolete LCG find-modules (each in a separate commit so they can easily be resurrected if needed):
-
FindHerwigpp
(superseded by herwig3 and dropped in LCG 98) -
Findblackhat
(not maintained, dropped in LCG > 93) -
FindQwt
(Qt Widgets, only in LCG <= 93) -
FindCASTOR
(long replaced by eos) -
Finddpm
module (disk pool manager only in LCG <= 95) -
PyXML
(not maintained anymore)
Neither of them is functional in LCG 102 and version history has been verified on https://lcginfo.cern.ch.
