How do I link gtk library more easily with cmake in windows?

2019-10-29 EDIT: While this answer could still work, please note that CMake has evolved a lot since my original answer in 2011. Do some search on “modern CMake” as there have been many syntactic and best practices changes.

Original Answer:

Just add the directory that contains pkg-config (which is in your gtk-bundle/bin directory) to your PATH. That way, CMake will find it.

Here’s a CMakeLists.txt for a sample application written in GTK2:

cmake_minimum_required (VERSION 2.4)
project (gtk-test)

find_package (PkgConfig REQUIRED)
pkg_check_modules (GTK2 REQUIRED gtk+-2.0)

include_directories (${GTK2_INCLUDE_DIRS})
link_directories (${GTK2_LIBRARY_DIRS})
add_executable (gtk-test main.c)
add_definitions (${GTK2_CFLAGS_OTHER})
target_link_libraries (gtk-test ${GTK2_LIBRARIES})

And the main.c file for my test app:

#include <gtk/gtk.h>

int main (int argc, char **argv)
{
    GtkWidget *window;

    gtk_init (&argc, &argv);

    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title (GTK_WINDOW (window), "Hello world !");
    g_signal_connect (G_OBJECT (window), "destroy", gtk_main_quit, NULL);

    gtk_widget_show_all (window);
    gtk_main ();

    return 0;
}

I tested it on Win XP with CMake 2.4 and CMake 2.8 and MinGW, and it works. It should also work outside MinGW.
