GTK Vala can't find gtk+-3 even though it is installed

I'm trying to create a simple GUI application with Vala to demonstrate running a basic application which shows a Gtk.Window. (I'm running Fedora 25 with up to date packages if it helps at all)

My window.vala file looks like this:

using GLib;
using Gtk;

class MWindow : Window {
    public MWindow(){
        //this.type = WindowType.TOPLEVEL;
        this.border_width = 12;
        this.destroy.connect(Gtk.main_quit);

        Button btn = new Button.with_label("Click");
        btn.clicked.connect(() => {
            btn.label = "clicked already";
        });

        this.add(btn);
        this.show_all();
    }

    public static int main(string[] args){
        MWindow mwin = new MWindow();
        Gtk.main();
        return 0;
    }
}

I'm compiling it like this:

valac --pkg gtk+-3.0 window.vala

I receive this error:

window.vala.c:7:21: fatal error: gtk/gtk.h: No such file or directory
 #include <gtk/gtk.h>
                     ^
compilation terminated.

I can't understand what is wrong because I have gtk+-devel and gtk3-devel installed as well as gtk+ and gtk3 installed. Is there something simple I'm missing? (I looked at this Stack Overflow question, but it isn't applicable to this problem).

The solution, as pointed out by Jens Mühlenhoff, was to run:

pkg-config --cflags gtk+3.0

and check it's output, which gave an error about X11 missing.

I had libX11-devel.i686, but not libX11-devel.x86_64, so I installed that package and the build worked.
