Compilando um software com o GTK que não possui script de configuração

Question

Eu esbarrei no verde , um visualizador de PDF para o Framebuffer. Eu gostaria de compilá-lo, mas não estou tendo muito sucesso, apesar de ter instalado todas as dependências ...

O erro que estou recebendo é:

Obviamente, ele não consegue encontrar GdkPixbuf, mas esta construção é definida em:

# ls /usr/include/gdk-pixbuf-2.0/gdk-pixbuf/gdk-pixbuf.h 
/usr/include/gdk-pixbuf-2.0/gdk-pixbuf/gdk-pixbuf.h

Quando eu adiciono ao arquivo sdl.c a seguinte linha:

#include <gdk-pixbuf/gdk-pixbuf.h>

Eu sou "saudado" com o seguinte erro:

# make
cc -Os -Wall -c sdl.c $(pkg-config poppler-glib --cflags) $(sdl-config --cflags) -o sdl.o
sdl.c:20:35: fatal error: gdk-pixbuf/gdk-pixbuf.h: No such file or directory
compilation terminated.
make: *** [sdl.o] Error 1

A minha pergunta é, então, como convencer o gcc a compilar este código?

Obrigado antecipadamente, Oz

ATUALIZAÇÃO:

com:

#include "/usr/include/gdk-pixbuf-2.0/gdk-pixbuf/gdk-pixbuf.h"
#include "/usr/include/gdk-pixbuf-2.0/gdk-pixbuf/gdk-pixbuf-core.h"
#include "/usr/include/gdk-pixbuf-2.0/gdk-pixbuf/gdk-pixbuf-features.h"
#include "/usr/include/gdk-pixbuf-2.0/gdk-pixbuf/gdk-pixbuf-enum-types.h"

adicionado ao sdl.c

Meu palpite é que existe alguma flag do gcc que eu estou perdendo? ou ligando?

Uma espécie de resposta, não totalmente compilada, mas consegui resolver a parte em que o sdl.c não consegue compilar:

cc -c sdl.c 'sdl-config --cflags' 'pkg-config poppler-glib --cflags' 'pkg-config gtk+-2.0 --cflags' -o sdl.o
