meson: pass library install paths to g-ir-scanner We are patching g-ir-scanner to produce absolute paths in the GIR files. When an application uses an internal library placed in a non-standard path (e.g. $out/lib/gnome-shell), the scanner needs to be informed. For autotools-based apps, the full path was obtained from libtool-wrapped files; with Meson, this is no longer possible – we need to pass the path information in some other way. This commit channels the --fallback-library-path option added to g-ir-scanner in aforementioned patch. 2017-11-09 02:48:26 +00:00			`--- a/mesonbuild/modules/gnome.py`
