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)
The system is Linux 64bit, Debian unstable, qt version 4.7.3, cmake version 2.8
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
People will have to change the cache values of OPENGL_glu_LIBRARY and OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX
