#clangd 'gtk/gtk.h' file not found

So, I'm trying to use clangd for the first time, I did however get the same errors with ccls, so it's probably something about my setup which is wrong.

This is my only C file, which contains the GTK example code:

#include <gtk/gtk.h>

static void print_hello (GtkWidget *widget,
             gpointer   data)
{
  g_print ("Hello World\n");
}

static void
activate (GtkApplication *app,
          gpointer        user_data)
{
  GtkWidget *window;
  GtkWidget *button;

  window = gtk_application_window_new (app);
  gtk_window_set_title (GTK_WINDOW (window), "Window");
  gtk_window_set_default_size (GTK_WINDOW (window), 200, 200);

  button = gtk_button_new_with_label ("Hello World");
  gtk_widget_set_halign (button, GTK_ALIGN_CENTER);
  gtk_widget_set_valign (button, GTK_ALIGN_CENTER);

  g_signal_connect (button, "clicked", G_CALLBACK (print_hello), NULL);
  g_signal_connect_swapped (button, "clicked", G_CALLBACK (gtk_window_destroy), window);

  gtk_window_set_child (GTK_WINDOW (window), button);

  gtk_window_present (GTK_WINDOW (window));
}

int
main (int    argc,
      char **argv)
{
  GtkApplication *app;
  int status;

  app = gtk_application_new ("org.gtk.example", G_APPLICATION_DEFAULT_FLAGS);
  g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);
  status = g_application_run (G_APPLICATION (app), argc, argv);
  g_object_unref (app);

  return status;
}

It is unable to find gtk/gtk.h even though it is installed.
If I run gcc -o main $(pkg-config --cflags --libs gtk4) *.c the application runs, everything is perfect. But I'm unable to make use of an LSP, probably because I have configured clangd wrong.
I have a compile_flags.txt, but I'm not even sure what to put into it. The documentation for clangd and ccls configuration is very vague.

I'm on Linux, if that's relevant.

compile_flags.txt is very simple, you just put the flags you would give to the compiler. You could pkg-config --cflags gtk4 > compile_flags.txt and get a starting point

#

I can't remember if 1 flag per line is required so you might have to break it up into lines
