I’m working on a project that generates a library C++ that will be shared to other teams.

• This library depends on OpenCV

To develop this I’m using a Docker image based on Ubuntu and installing libopencv-dev:

FROM ubuntu:22.04 as base
ENV DEBIAN_FRONTEND noninteractive

RUN apt -q update -y && apt -q install -y 
    build-essential 
    cmake 
    gdb 
    wget 
    libopencv-dev 
    ffmpeg 
    libavformat-dev 
    libavcodec-dev 
    libswscale-dev

Then I use a CMakelists.txt file to deal with the compilation, the lines I use for OpenCV are:

SET(MY_OPENCV_COMPONENTS photo objdetect imgproc features2d core)
find_package(OpenCV COMPONENTS ${MY_OPENCV_COMPONENTS} )

message(STATUS "OpenCV libraries: ${OpenCV_LIBS}")

This works great and generates a file my_lib.so with our functionalities.

The Problem
After sending my_lib.so to other teams they complained about it depending on the debug version of OpenCV and them needing the release version. Which makes sense.

I tested this using:

ldd my_lib.so  | grep open
        libopencv_calib3d.so.4.5d => /lib/x86_64-linux-gnu/libopencv_calib3d.so.4.5d (0x000072082f29a000)
        libopencv_features2d.so.4.5d => /lib/x86_64-linux-gnu/libopencv_features2d.so.4.5d (0x000072082f1e4000)
        libopencv_imgcodecs.so.4.5d => /lib/x86_64-linux-gnu/libopencv_imgcodecs.so.4.5d (0x000072082f18b000)
        libopencv_imgproc.so.4.5d => /lib/x86_64-linux-gnu/libopencv_imgproc.so.4.5d (0x000072082ec5e000)
        libopencv_core.so.4.5d => /lib/x86_64-linux-gnu/libopencv_core.so.4.5d (0x000072082e8ee000)
        libopencv_flann.so.4.5d => /lib/x86_64-linux-gnu/libopencv_flann.so.4.5d (0x000072082e325000)
        libopenjp2.so.7 => /lib/x86_64-linux-gnu/libopenjp2.so.7 (0x000072082df32000)

Which actually shows the OpenCV libraries in Debug mode.

• So, how do I use the Release version?

1. I tried installing python3-opencv instead, but still got the libs with d denoting debug.
2. I want to avoid compiling the source code myself to be generic.
3. I tried to look for compiled binaries for Ubuntu online with no luck.
