【问题描述】：
我正在尝试使用cmake 编译一个项目。给我的指示是需要 Qt 4.8。从qt-project.org/downloads 下载。编译安装Qt 4.8：
mazdak@lnxamindai> qmake -query
QT_INSTALL_PREFIX:/usr/local/Trolltech/Qt-4.8.5
QT_INSTALL_DATA:/usr/local/Trolltech/Qt-4.8.5
QT_INSTALL_DOCS:/usr/local/Trolltech/Qt-4.8.5/doc
QT_INSTALL_HEADERS:/usr/local/Trolltech/Qt-4.8.5/include
QT_INSTALL_LIBS:/usr/local/Trolltech/Qt-4.8.5/lib
QT_INSTALL_BINS:/usr/local/Trolltech/Qt-4.8.5/bin
QT_INSTALL_PLUGINS:/usr/local/Trolltech/Qt-4.8.5/plugins
QT_INSTALL_IMPORTS:/usr/local/Trolltech/Qt-4.8.5/imports
QT_INSTALL_TRANSLATIONS:/usr/local/Trolltech/Qt-4.8.5/translations
QT_INSTALL_CONFIGURATION:/etc/xdg
QT_INSTALL_EXAMPLES:/usr/local/Trolltech/Qt-4.8.5/examples
QT_INSTALL_DEMOS:/usr/local/Trolltech/Qt-4.8.5/demos
QMAKE_MKSPECS:/usr/local/Trolltech/Qt-4.8.5/mkspecs
QMAKE_VERSION:2.01a
QT_VERSION:4.8.5
但是，在编译项目时，我收到以下错误：
root@lnxamindai> cmake .
-- Setting flags for GNU GCC

这让我很困惑，不是应该安装OpenGL库吗？
【问题讨论】：
-
你还没有显示你的 cmake 文件...
-
我猜你的意思是 Cmakelists？
-
请提供一个独立的例子，而不是像这样臃肿。 sscce.org。另外，我不明白为什么你应该只使用 QT_INCLUDES 时使用 OPENGL_INCLUDE_DIR (ADVANCED)。
-
@Mazze 别担心他；他给人的印象相当...严厉（您可以在他的页面上阅读他过去的cmets，以意识到这始终是他的语气，因此您不应该感到有针对性）。他要求你删除
CMakeLists.txt中与QT无关的所有部分。 -
@LaszloPapp 只是因为你问 OP “你为什么要为自己辩护？”如果 OP 对您的问题感到防御，那么他们可能不想发布更多内容来澄清，这让双方都感到沮丧。我只是不确定是否有必要在友好的网站上（即使它是技术性的）具有侵略性。话虽如此，我明确表示我不会比你更进一步对此发表评论，所以你有最后的发言权。
