+Subject: [PATCH] Don't install glade files outside build prefix
+
+When using pkg-config variables to get installation directory locations,
+we must be careful to redefine any pkgconfig variables necessary to
+ensure the installation does not occur outside the build prefix. We
+could do, e.g.:
+
+module_dir = gladeui_dep.get_pkgconfig_variable(
+    'moduledir',
+    define_variable: ['libdir', libdir)])
+
+Except in the particular case of glade, this is not possible because the
+pkg-config file uses absolute paths (i.e. the moduledir variable is not
+relative to libdir, and not even relative to prefix!) so there's no way
+to override it. This means we can't use the pkg-config directories at
+all.
+
+If bored, fixing glade might be fun to do. In the meantime, we'll need
+to install these manually. This fixes the files being installed under
+/usr instead of /app when building a Fedora flatpak.
