opencv_world library

[astropiu]

I have built opencv4.4 with opencv_world flag turned on.
So, I only have a large single .so file which is opencv_world.so . But building caffe seems to need individual .so files of opencv:

CXX src/caffe/layer.cpp
CXX src/caffe/parallel.cpp
AR -o .build_release/lib/libcaffe.a
LD -o .build_release/lib/libcaffe.so.1.0.0
/usr/bin/ld: cannot find -lopencv_core
/usr/bin/ld: cannot find -lopencv_highgui
/usr/bin/ld: cannot find -lopencv_imgproc
collect2: error: ld returned 1 exit status
make: *** [Makefile:583: .build_release/lib/libcaffe.so.1.0.0] Error 1

Is there any workaround this or do I need to rebuild opencv?

And also I was facing several issues with cudnn accelation on for cudnn 8.0. I suppose there isnt a fix to this yet?

• CUDA version: 11
• CUDNN version : 8
• OpenCV : 4.4.0
