GLFW не може да се свърже

Опитвам се да компилирам тестовата програма по-долу:

#include <GL/glfw.h>

int main(int argc, char** argv) {
    if(!glfwInit()) {
        return -1;
    }

    if(!glfwOpenWindow(640, 480, 8, 8, 8, 0, 24, 0, GLFW_WINDOW)) {
        return -1;
    }

    while(glfwGetWindowParam(GLFW_OPENED)) {
        glfwSwapBuffers();
    }

    return 0;
}

но винаги получавам undefined reference грешки по отношение на функциите на GLFW.

По-долу е моят makefile:

CXX = clang++
CXXFLAGS = -Wall -std=c++0x
LDFLAGS = -lglfw

OBJ_DIR = bin
LIB_DIR = -L/usr/lib
INC_DIR = -I/usr/include

SOURCE = main.cpp
OBJECTS = ${SOURCE:%.cpp=$(OBJ_DIR)/%.o}
EXECUTABLE = hello

all: init $(OBJECTS) $(EXECUTABLE)

$(EXECUTABLE):
    $(CXX) $(CXXFLAGS) $(LDFLAGS) $(LIB_DIR) -o $@ $(OBJECTS)

$(OBJ_DIR)/%.o: %.cpp
    $(CXX) $(INC_DIR) -c $< -o $@

init:
    @mkdir -p "$(OBJ_DIR)"

clean:
    @rm -rf $(OBJ_DIR) $(EXECUTABLE)

Определено имам glfw.h и libglfw.a/.so, тъй като когато стартирам locate glfw получавам:

:~$ locate glfw
/usr/include/GL/glfw.h
/usr/lib/libglfw.a
/usr/lib/libglfw.so
/usr/lib/libglfw.so.2
/usr/lib/libglfw.so.2.6

Резултатът от nm /usr/lib/libglfw.a | grep glfwInit:

:~$ nm /usr/lib/libglfw.a | grep glfwInit
                 U _glfwInitialized
                 U _glfwInitialized
                 U _glfwInitialized
                 U _glfwInitialized

                 U _glfwInitialized
                 U _glfwInitialized
                 U _glfwInitJoysticks
                 U _glfwInitTimer
00000000000000c0 T _glfwInitJoysticks
0000000000000000 T _glfwInitTimer

и многословното съобщение от clang:

Изглежда, че не намира библиотеката?
