Rewrite ncurses searching.

First, look for ncursesw, via pkg-config files and the include/library.
Then fallback to plain ncurses, via the same.

Also, try to determine the header to include in a more portable way that
doesn't assume /usr/include as base path.
#include "gntutils.h"
int main()
{
GntWidget *win, *button;
gnt_init();
gnt_util_parse_widgets("<vwindow id='0' fill='0' align='2'><label>This is a test.</label><button id='1'>OK</button></vwindow>", 2, &win, &button);
g_signal_connect_swapped(G_OBJECT(button), "activate", G_CALLBACK(gnt_widget_destroy), win);
gnt_widget_show(win);
gnt_main();
gnt_quit();
return 0;
}
