如何将一个目录添加到PKG_CONFIG_PATH环境变量？(How to add a direct

林新使用Ubuntu，问题是，我想安装OpenCV，然后我想用这句话来查看已安装的程序的版本

pkg-config --modversion opencv

然后，终端显示我这种类型的“错误”的

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

我试图做的一切，它不工作，有人知道如何解决它？

apt install libopencv-dev
