-To build this branch, you first need to build the AccessKit C bindings. To do that, check out AccessKit and follow the instructions in `bindings/c/README.md`. Note that running `cmake --install` on that project doesn't install the library system-wide, but only copies files into the `include` and `lib` directories under `bindings/c`.

Note that running `cmake --install` on that project doesn't install the library system-wide, but only copies files into the `include` and `lib` directories under `bindings/c`.
 
 Then, when building GTK in this branch, include the following option in the `meson setup` command:
