# --includedir= path maintains a few properties:
# 1. have stable name across libffi versions: some packages like
# dev-lang/ghc or kde-frameworks/networkmanager-qt embed
# ${includedir} at build-time. Don't require those to be
# rebuilt unless SONAME changes. bug #695788
#
# We use /usr/.../${PN} (instead of former /usr/.../${P}).
#
# 2. have ${ABI}-specific location as ffi.h is target-dependent.
#
# We use /usr/$(get_libdir)/... to have ABI identifier.
