long_description    Library that gives emulators the necessary tools to \
                    implement a virtio-gpu device, in particular one with 3D support.

# This port builds different depending on whether libepoxy is installed +x11 or
# +quartz. If libepoxy is +quartz and virglrenderer is installed from a binary,
# it fails to run because it expects an X11-specific symbol in libepoxy that
# isn't there.
#
# Add empty variants that do nothing but ensure this port is built with the
# same variants as libepoxy, and that a binary isn't used when libepoxy +quartz
# is installed.

# TODO: Any tests?
# TODO: Currently this Portfile is only for the variant required for use in libkrun. There should (maybe) be a normal variant and then a +krunkit or +libkrun variant which is the equivalent of this. Look at that later, just get krunkit working for now.
