Minimal example fails to build - archiver error

I’m unable to build even the simplest project with web-view, as the build script from webview-sys crashes with an error I couldn’t find anywhere on the issue tracker - ar can’t find libwebview.a.
My main.rs is just the minimal wikipedia example, and my Cargo.toml only has web-view as a dependency.
I’m on Arch Linux, webkit2gtk is installed and pkg-config can find it:

$ pkg-config --cflags --libs webkit2gtk-4.0
-I/usr/include/webkitgtk-4.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/gtk-3.0 -I/usr/include/pango-1.0 -I/usr/include/harfbuzz -I/usr/include/freetype2 -I/usr/include/libpng16 -I/usr/include/libmount -I/usr/include/blkid -I/usr/include/fribidi -I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/gio-unix-2.0 -I/usr/include/cloudproviders -I/usr/include/atk-1.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include -I/usr/include/at-spi-2.0 -I/usr/include/libsoup-2.4 -pthread -I/usr/include/libxml2 -lwebkit2gtk-4.0 -lgtk-3 -lgdk-3 -lz -lpangocairo-1.0 -lpango-1.0 -lharfbuzz -latk-1.0 -lcairo-gobject -lcairo -lgdk_pixbuf-2.0 -lsoup-2.4 -lgio-2.0 -ljavascriptcoregtk-4.0 -lgobject-2.0 -lglib-2.0 

Here’s the error I’m getting:

$ cargo build

The following warnings were emitted during compilation:

It looks to me like a bug but I’m not 100% sure. Either way I’d love to get some help so I can use this library, it’s perfect for my use case.

Thanks in advance for any help!

Published new patch version 0.7.2 with this fix.

@helgoboss yes, it won’t compile and I think what @gBopHuk said is correct. GTK APIs should be provided by gtk module.
