编译错误：由libQt5Core.so.5需要libicui18n.so.54没有找到

Question

#include <opencv2/opencv.hpp> //头文件 
using namespace cv; //包含cv命名空间 

int main() 
{ 
    Mat img=imread("cornea.jpg"); 
    imshow("src",img); 
    waitKey(0); 
    return 0; 
} 

和我一起编译：

g++ test.cpp -o test pkg-config opencv --cflags --libs opencv 

这给了我：

中的反引号命令行pkg-config opencv --cflags --libs opencv是不可见的。我现在没有理由。

的确，在早期，我已经安装了Qt。但是现在，我不希望我的程序与Qt有关。为了让我的程序不受Qt库函数的影响，我在/etc/bash.bashrc文件中屏蔽了Qt的路径变量，并安装了一个新的gcc 5.3.0。但同样的错误仍然存​​在！

我使用Ubuntu 14.04

下载ICU-54.1从这里 http://www.linuxfromscratch.org/blfs/view/7.7/general/icu.html 并手动安装。 对我来说，这解决了这个问题。
