@vfbsilva I believe you only need to do that if you are using just the Makefile. This package uses darknet's CMakeLists.txt which does properly find opencv.

Opencv was not being properly found. I did a dirty hack I'm not even sure is right:
export PKG_CONFIG_PATH=/usr/lib/pkgconfig sudo cp -p /usr/lib/pkgconfig/opencv4.pc /usr/lib/pkgconfig/opencv.pc
I think I could have modified the makefile but my test did work so I kept it.

Is it possible to do a clean build of a package using yaourt? If not can you manually build the package without using an AUR helper or use one that does allow you to do that like yay?

@vfbsilva What is the output of pacman -Ss opencv?

Oki I had to fix my opencv import so I would fall on the opencv case of the make file but then it does not build:
=> Installing files cp: não foi possível obter estado de '/tmp/yaourt-tmp-imanewbie/aur-darknet-alexeyab-git/src/darknet/build-release/uselib_track': Arquivo ou diretório inexistente ==> ERRO: Uma falha ocorreu em package(). Abortando... ==> ERRO: Makepkg não conseguiu compilar darknet-alexeyab-git. ==> Reiniciar a compilação de darknet-alexeyab-git ? [s/N]
imanewbie@mordor pkg-config --modversion opencv 4.1.0

It does install but does not worK: sh image_yolov2.sh ./darknet: error while loading shared libraries: libopencv_stitching.so.3.4: cannot open shared object file: No such file or directory

Added vtk as a make dependency to suppress issues that are due to either upstream darknet or opencv. Should install successfully now.

I was able to replicate the issue with opencv 4.1 as well. Since this is an upstream version, we should get the developers in loop as well. I see an issue has been posted there: https://github.com/AlexeyAB/darknet/issues/3406
