I\'m trying to use opencv 4 in QT creator, I\'m working on Mac but I can\'t be able to link the library, I always have a error like on picture 2.

So, I have a solution here, I have install the OpenCV 4. In
/usr/local/Cellar/opencv/4.2.0_1/lib/pkgconfig
I have a opencv4.pc not opencv.pc and the "opencv development package not found" error came from here.
Edit your .pro file with
QT_CONFIG -= no-pkg-config
CONFIG += link_pkgconfig
PKGCONFIG += opencv4
note that it's opencv4.
after you have to configure the Build Environment in Qt Creator normally.
