pkg-config 路徑問題

例如：

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

 

設置環境變量PKG_CONFIG_PATH方法舉例如下：

 

找到 opencv.pc所在文件夾 比如 /test/

 

設置為環境變量

 

export PKG_CONFIG_PATH=/test/:$PKG_CONFIG_PATH
