cmake不使用QtOpenGL链接libGLU [英] cmake doesn't link libGLU using QtOpenGL

问题描述

我正在尝试编译使用QtOpenGL的软件，但由于没有-lGLU，所以出现了链接错误. 使用cmake. 在我看来，CMakeLists.txt文件中唯一相关的行是find_package(Qt4 REQUIRED)

I'm trying to compile a software that uses QtOpenGL, but I got a link error because -lGLU is not present. cmake is used. The only relevant line in CMakeLists.txt files seems to me find_package(Qt4 REQUIRED)

系统为Linux 64位，Debian不稳定，qt版本4.7.3，cmake版本2.8

The system is Linux 64bit, Debian unstable, qt version 4.7.3, cmake version 2.8

推荐答案

GLU既不是OpenGL的一部分，也不是Qt的一部分.您必须手动将其添加为附加依赖项； CMake FindOpenGL模块还搜索GLU

GLU is neither part of OpenGL nor Qt. You must add it as an additional dependency manually; the CMake FindOpenGL module also searches for GLU

% cmake --help-module FindOpenGL
cmake version 2.8.1
  FindOpenGL
       Try to find OpenGL

       Once done this will define


         OPENGL_FOUND        - system has OpenGL
         OPENGL_XMESA_FOUND  - system has XMESA
         OPENGL_GLU_FOUND    - system has GLU
         OPENGL_INCLUDE_DIR  - the GL include directory
         OPENGL_LIBRARIES    - Link these to use OpenGL and GLU


       If you want to use just GL you can use these values

         OPENGL_gl_LIBRARY   - Path to OpenGL Library
         OPENGL_glu_LIBRARY  - Path to GLU Library


       On OSX default to using the framework version of opengl

人们会 必须更改OPENGL_glu_LIBRARY的缓存值，并 OPENGL_gl_LIBRARY在OSX上将OpenGL与X11一起使用

People will have to change the cache values of OPENGL_glu_LIBRARY and OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX
