# Builds the profiler as an AppImage. The Wayland client libraries are built
# from a pinned release and bundled, so the core protocol version does not
# depend on what the build host provides. Everything else that is host-coupled
# (glibc, EGL, dbus, xkbcommon, OpenSSL) is left to the target system, which
# is expected to be reasonably current. The build host sets the glibc floor,
# so this should run on the oldest distro release that is still supported.
