參考資料：

在pkg-config搜索路徑中找不到軟件包opencv

我做了一個(gè)名為“opencv.pc”的文件，并將其復(fù)制到“/usr/local/lib / pkgconfig”
然后我添加這兩行到“.bashrc”：

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

而已！一切都OK了。

該文件的內(nèi)容為：

prefix=/usr
exec_prefix=${prefix}
includedir=${prefix}/include
libdir=${exec_prefix}/lib
