若要在 Debian 11 上使用 OpenCV 4,您需要确保正确设置了 pkg-config。可以按照以下步骤操作:
1. 安装 OpenCV 4
使用以下命令安装 OpenCV 4:
```
sudo apt-get update
sudo apt-get install libopencv-dev
```
2. 设置 pkg-config
确保在 `/usr/lib/pkgconfig/` 目录下有一个名为 `opencv4.pc` 的文件。如果该文件不存在,则可以手动创建它。使用以下命令创建该文件:
```
sudo touch /usr/lib/pkgconfig/opencv4.pc
```
编辑该文件,并将以下内容添加到其中:
```
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir_old=${prefix}/include
includedir_new=${prefix}/include/opencv4
includedir=${includedir_new}
Name: OpenCV

Cflags: -I${includedir} -I${includedir}/opencv -I${includedir}/opencv2 -I${includedir}/opencv2/face -I${includedir}/opencv2/rgbd -I${includedir}/opencv2/saliency -I${includedir}/opencv2/sfm -I${includedir}/opencv2/stereo -I${includedir}/opencv2/structured_light -I${includedir}/opencv2/superres -I${includedir}/opencv2/tracking -I${includedir}/opencv2/xfeatures2d -I${includedir}/opencv2/ximgproc
```
保存并关闭文件。
现在,当您使用 OpenCV 4 编译代码时,您应该可以使用 pkg-config 来获得必要的编译选项和库路径。例如,您可以使用以下命令来获取编译选项:
```
pkg-config --cflags opencv4
```
或者,您可以使用以下命令来获取库路径:
```
pkg-config --libs opencv4
```
