Hello,  
I try to use c++ with opencv for the first time.I read various tutorial like those one:  
[for vscode](https://duckduckgo.com/?t=ffab&q=opencv+c%2B%2B&iax=videos&ia=videos&iai=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Dm9HBM1m_EMU)  
[on Linux](https://docs.opencv.org/4.x/d7/d9f/tutorial_linux_install.html)  
[in terminal](https://opencvguide.readthedocs.io/en/latest/opencvcpp/basics.html)  
But it’s still the same debuting error(he don’t find opencv):

```auto
,,main.cpp:2:10: fatal error: opencv2/opencv.hpp: No such file or directory
    2 | #include <opencv2/opencv.hpp>
      | ^ ~~~~~~~~~~~~~~~~~~~
compilation terminated.

```

Thanks for your help.
