[CMake] CMAKE 2.8.9, OS X 10.8 and OpenGL

[Jason T. Slack-Moehrle]

Hello All,

I am new to CMAKE and attempting to build an OpenGL app on OS X 10.8.
(I will be using other platforms as well)

My CMakeLists.txt:

cmake_minimum_required (VERSION 2.8.9)

SET(CMAKE_C_COMPILER "clang")
SET(CMAKE_CXX_COMPILER "clang++")
SET(CMAKE_CXX_FLAGS "-std=c++11 -stdlib=libc++")

IF(APPLE)
   INCLUDE_DIRECTORIES ( /System/Library/Frameworks )
   FIND_LIBRARY(COCOA_LIBRARY Cocoa)
   FIND_LIBRARY(GLUT_LIBRARY GLUT )
   FIND_LIBRARY(OpenGL_LIBRARY OpenGL )
   MARK_AS_ADVANCED (COCOA_LIBRARY
                     GLUT_LIBRARY
                     OpenGL_LIBRARY)
   SET(EXTRA_LIBS ${COCOA_LIBRARY} ${GLUT_LIBRARY} ${OpenGL_LIBRARY})
ENDIF (APPLE)
#target_link_libraries(Test ${EXTRA_LIBS})

project(Test)
add_executable(Test main.cpp)

My sample code:

#include <iostream>
#include <thread>

#include <stdlib.h>

#include <GLUT/glut.h>
#include <OpenGL/glext.h>
#include <OpenGL/gl.h>
#include <OpenGL/glu.h>

void display(void)
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSwapBuffers();
}

void reshape(int width, int height)
{
    glViewport(0, 0, width, height);
}

void idle(void)
{
    glutPostRedisplay();
}

int main(int argc, char** argv)
{
    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGBA | GLUT_DOUBLE | GLUT_DEPTH);
    glutInitWindowSize(640, 480);

    glutCreateWindow("GLUT Program");

    glutDisplayFunc(display);
    glutReshapeFunc(reshape);
    glutIdleFunc(idle);

    glutMainLoop();
    return EXIT_SUCCESS;
}

and I am getting the following:

$ cmake .

Can anyone help me see my error?
