Perhaps you should add the directory containing `nettle.pc' to the PKG_CONFIG_PATH environment variable

as follows:

1. Open a terminal window.

2. Type the following command:

   export PKG_CONFIG_PATH=/path/to/directory/containing/nettle.pc:$PKG_CONFIG_PATH

Replace "/path/to/directory/containing/nettle.pc" with the actual path to the directory that contains the "nettle.pc" file.

3. Press Enter.

This will add the directory containing "nettle.pc" to the PKG_CONFIG_PATH environment variable, allowing pkg-config to locate the nettle package when you try to compile your program.

Package opencv was not found in the pkg-config search path. Perhaps you should add the directory containing `opencv.pc' to the PKG_CONFIG_PATH environment variable No package 'opencv' found

这个错误通常是由于没有正确安装OpenCV或者没有正确配置环境变量所导致的。可以尝试以下解决方法：

1. 确认已正确安装OpenCV，并且安装路径已经添加到系统环境变量中。

2. 如果确认已经正确安装OpenCV，但是仍然出现这个错误，可以尝试手动设置PKG_CONFIG_PATH环境变量。例如，如果OpenCV的安装路径为/opt/OpenCV，则可以使用以下命令设置环境变量：

export PKG_CONFIG_PATH=/opt/OpenCV/lib/pkgconfig:$PKG_CONFIG_PATH

3. 如果手动设置PKG_CONFIG_PATH环境变量仍然无法解决问题，可以尝试重新安装OpenCV，并确保在安装过程中选择了正确的路径和选项。

希望这些解决方法可以帮到你！

未在 pkg-config 搜索路径中找到 opencv 包。也许你应该将包含 “opencv.pc” 的目录添加到 pkg_config_path 环境变量中，没有找到名为 “opencv” 的包。
