+Subject: [PATCH] meson.build: dont look for flatpak http_backend variable
+
+flatpak 1.17.1 release dropped libsoup2 support:
+[https://github.com/flatpak/flatpak/blob/c324778b0720cb2d01c217fdc70358e232c38b4d/NEWS#L20]
+
+* Drop libsoup2 support in favor of libcurl. The `http_backend` build option has
+  been dropped as well. (#6395)
+
+gnome-software still searches for the http_backend variable and fails:
+ ../sources/gnome-software-49.1/meson.build:218:32: ERROR: Could not get pkg-config variable and no default provided for <PkgConfigDependency flatpak: True ['>= 1.14.1']>
