用homebrew安装带有contrib的OpenCV

Question

我通过此命令brew install opencv3 --with-contrib和setup pgk_config_path安装了opencv with contrib by homebrew，如下所示。

export PKG_CONFIG_PATH=$usr/local/Cellar/opencv3/3.2.0/lib/pkgconfig:$PKG_CONFIG_PATH

我确认目录中存在opencv.pc。但是当编译c ++文件时，得到以下错误。

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

我使用mac OS Sierra。请帮帮我。
