使用Qt + opencv + ffmpeg时，Mac上的架构x86_64找不到符号

I'm running a project using Qt+opencv+ffmpeg on Mac, but it comes to an error: symbol(s) not found for architecture x86_64.

我正在Mac上使用Qt + opencv + ffmpeg运行一个项目,但它出现了一个错误:找不到架构x86_64的符号。

Part of .pro:

.pro的一部分:

INCLUDEPATH += /usr/local/include
INCLUDEPATH += /usr/local/include/opencv
INCLUDEPATH += /usr/local/include/opencv2

LIBS += -L/usr/local/lib -lavformat -lavcodec -lavutil

When I use GCC (x86 64bit in /usr/bin) to compile, it shows

当我使用GCC(/ usr / bin中的x86 64位)进行编译时,它会显示出来

error: symbol(s) not found for architecture x86_64

When I use Clang (x86 64bit in /usr/bin) to compile, it shows

You have included the path with INCLUDEPATHbut not the library itselfs with LIBS

您已将INCLUDEPATH的路径包含在内,而不是LIBS中的库本身
