# QEMU 11.1.2: the PC emulator the Haiku ports (src/hosted/be) are run and
# gated in, x86_64 and i386 system emulation only, with KVM when /dev/kvm is
# usable. Built from the release source into toolchains/opt/qemu, with
# pixman 0.46.4 (its display library, which distributions split into a -dev
# package that may be missing) built first as a static library and linked
# in. SDL2 gives joey-run its window; the wav audio backend the audio gate
# records through is always built in.
