c - 如何让 clion 使用以下 make 和 pkg-config？

Question

我有以下简单的 C 程序，它通知我我在 Xfce 中的工作区。我可以成功编译它并通过命令使用它

gcc -O2 -DWNCK_I_KNOW_THIS_IS_UNSTABLE -o wsnd pkg-config --cflags --libs libnotify --libs libwnck-1.0 wsn.c

但我如何设置 Cmake 配置文件，以便 clion 也能编译它？如何在 Cmake 中使用 pkg-config？

#include <libnotify/notify.h>
#include <libwnck-3.0/libwnck/libwnck.h>

#define N_SUMMARY "Workspace Changed"
#define N_ICON    "dialog-information"
#define N_APPNAME "workspace switch notifier"
#define N_TIMEOUT 2000 /*2000ms = 2s */

static NotifyNotification * m_notification = NULL;

static void
on_active_workspace_changed (WnckScreen    *screen,
                             WnckWorkspace *space,
                             gpointer      data)
{

    WnckWorkspace * active_workspace = wnck_screen_get_active_workspace(screen);
    const char * w_name = wnck_workspace_get_name (active_workspace);

    notify_notification_update(m_notification, N_SUMMARY, w_name, N_ICON);
    notify_notification_show(m_notification, NULL);
}

int main(int argc, char ** argv)
{

    GMainLoop *loop;
    WnckScreen *screen;

    if (notify_init(N_APPNAME))
        m_notification = notify_notification_new(N_SUMMARY, "" , N_ICON);
    else
        fprintf(stderr, "Failed to init notifications\n");
    notify_notification_set_timeout(m_notification, N_TIMEOUT);

    gdk_init (&argc, &argv);

    loop = g_main_loop_new (NULL, FALSE);
    screen = wnck_screen_get_default();

    g_signal_connect (screen, "active-workspace-changed",
                      G_CALLBACK (on_active_workspace_changed), NULL);

    g_main_loop_run (loop);

    g_main_loop_unref (loop);

    return 0;
}

遵循 CMakeLists.txt 配置使其工作。我现在也可以在源代码中跟踪函数调用。
