libQt5Core.so.5的OpenCV未定义引用

在开始之前，我想指出实际上存在一个非常相似（可能完全相同）的问题。但是，从接受的答案来看，我一直无法解决自己的问题。

我按照该网站提供的说明在Ubuntu 16.04上安装OpenCV3。我到了试图用g ++编译测试程序（第6节）的地步。编译返回以下内容：

尝试将此答案应用于我的问题时，我尝试将Qt5的安装路径本地化。我通过使用做到了dpkg --listfiles libqt5core5a。我将结果路径添加到LD_LIBRARY_PATH，但没有帮助。

我尝试通过重新安装Qt5sudo apt install qt5-default并进行了安装，qttools5-dev但它也没有帮助。

我的问题可能与编译器正在使用anaconda的库有关，而实际上我是在全局环境中工作的。更多的研究还显示，我使用的Qt5安装的apt install版本为5.5.1，而如果键入，qtdiag我会看到显示的版本为5.6.2。那可能是因为在某个时候我可能也已经在anaconda下安装了Qt5。因此，我可能有2个安装。我不知道该如何验证。

是什么原因引起的？

编辑：

多亏了这些评论，我才意识到anaconda3甚至不应该PATH放在首位。经过一番黑客攻击后，我发现它是在登录时添加到路径中的.bashrc，这可能是因为在安装Anaconda时提出了这样的要求。我将其删除，然后make再次尝试。

我现在看到的是（很长的输出摘录）：

/usr/local/lib/libopencv_highgui.so: undefined reference to `QGLWidget::~QGLWidget()@Qt_5'

这使我觉得我现在只是想念中的东西PATH。

我在这些子文件夹中找到了这些库的定义位置（在我安装的Qt5中）/usr/include/x86_64-linux-gnu/qt5/，然后PATH通过中的export命令将它们全部添加到.profile，然后运行source .profile。如果我现在跑步，echo $PATH我会看到它们全部就绪。

不幸的是，如果我运行make命令，错误消息仍然是相同的。

编辑＃2：

加入含QT5的头到所有子文件夹之后PATH，我尝试添加的副本PATH中LD_LIBRARY_PATH做

export  LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PATH

但是，错误消息的性质再次没有改变。我真的不明白为什么编译器看不到Qt5库。
