MacOS cannot find libadwaita
I am trying a simple window and trying to use Adwaita. The error I get when running "nim c..." is:

```
ld: library 'adwaita-1' not found
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```

I have GTK4 and libAdwaita installed via brew. The code for the app is simple:

```nim
import owlkettle
import owlkettle/adw

viewable App:
    text: string

method view(app: AppState): Widget =
    result = gui:
        Window:
            title = "Simple Window"

adw.brew(gui(App()))
```

If I use GTK4 itself by removing the "adw.brew..." and just using "brew...", and removing the adw import the code runs fine.

pkg-build shows the following output when running "pkg-config --libs libadwaita-1"

```
-L/opt/homebrew/Cellar/libadwaita/1.5.2/lib -L/opt/homebrew/Cellar/gtk4/4.14.4/lib

```

Am I doing something wrong or is MacOS not supporting Adwaita, or any other clues?

Thanks in advance!
