# Dependencies
# https://github.com/ruby-gnome/ruby-gnome/blob/master/glib2/README.md
# On linux for example
# https://www.gtk.org/docs/installations/linux/
# sudo apt install libgtk-4-dev
# Actually, glib2 [requires](https://github.com/ruby-gnome/ruby-gnome/blob/master/glib2/ext/glib2/extconf.rb#LL29C8-L29C35) libglib2.0-dev, which libgtk-4-dev depends on
# And you don't have to install it manually, as glib2 uses [mkmf-gnome](https://github.com/ruby-gnome/ruby-gnome/blob/master/glib2/lib/mkmf-gnome.rb),
# and it tries to [install missing native packages](https://github.com/ruby-gnome/ruby-gnome/blob/master/glib2/lib/mkmf-gnome.rb#LL480C23-L480C53)
