推荐答案

所以，我在这里有一个解决方案，我已经安装了OpenCV 4.在

So, I have a solution here, I have install the OpenCV 4. In

/usr/local/Cellar/opencv/4.2.0_1/lib/pkgconfig

/usr/local/Cellar/opencv/4.2.0_1/lib/pkgconfig

我有一个opencv4.pc而不是opencv.pc，"opencv开发包未找到"错误是从这里发出的.

I have a opencv4.pc not opencv.pc and the "opencv development package not found" error came from here.

使用

QT_CONFIG -= no-pkg-config
CONFIG  += link_pkgconfig
PKGCONFIG += opencv4 

请注意，它是opencv4.

note that it's opencv4.

必须正常配置Qt Creator中的构建环境之后.

after you have to configure the Build Environment in Qt Creator normally.
