链接GLUT和QGLViewer的问题

Question

我正在尝试编译Hernan编写的名为QCV的计算机视觉库，但我有很多与QGLViewer库相关的链接问题。编译器抛出的错误包括：

//usr/lib/x86_64-linux-gnu/libQGLViewer.so.2: undefined reference to `gluNewQuadric'
//usr/lib/x86_64-linux-gnu/libQGLViewer.so.2: undefined reference to `gluUnProject'
//usr/lib/x86_64-linux-gnu/libQGLViewer.so.2: undefined reference to `gluCylinder'
//usr/lib/x86_64-linux-gnu/libQGLViewer.so.2: undefined reference to `gluPickMatrix'
//usr/lib/x86_64-linux-gnu/libQGLViewer.so.2: undefined reference to `gluSphere'
//usr/lib/x86_64-linux-gnu/libQGLViewer.so.2: undefined reference to `gluProject'

这是与OpenGL/GLUT库相关的链接问题(我想)。我正在使用CMake进行编译，并且在CMakeLists.txt文件中正确地请求(并找到)了GLUT依赖项。CMake文件的相关部分如下：

##################################
# OpenGL
find_package(OpenGL REQUIRED)
find_package(GLUT REQUIRED)

target_link_libraries(imgPlayer ${QT_LIBRARIES} 
                                ${OPENGL_LIBRARIES} ${GLUT_LIBRARY}
                                ${QCV_LIB} 
                                ${CMAKE_THREAD_LIBS_INIT} 
                                ${OpenCV_LIBS})

以及"cmake“的输出。是

-- Found Qt4: /usr/bin/qmake-qt4 (found version "4.8.6") 
-- Found OpenGL: /usr/lib/x86_64-linux-gnu/libGL.so  
-- Found GLUT: /usr/lib/x86_64-linux-gnu/libglut.so  
-- Found OpenCV: /usr/local (found version "3.2.0") 
-- Configuring done
-- Generating done

编译器失败的可能原因是什么？

谢谢!

GLU不是供过于求。缺少的引用来自GLU库。在CMake中

target_link_libraries(
    …
    ${OPENGL_glu_LIBRARY}
    …
);
