+Subject: [PATCH] spa: bluez5: fix dependency on glib in bluez5_deps
+
+In de595a78ff958b8314d853f6266d5832529d9729, we started to require glib
+for building bluez and introduced dependencies for the needed gio* bits,
+but we only ever check for glib itself for gstreamer or flatpak.
+
+Drop glib from the dep list to match the summary() & subsequent bluez_deps_found
+logic in spa/meson.build.
+
