EDIT 1: I gave up on this, and compiled the big SHARED_LIBRARY libopencv_world.so.
I'm trying to configure an Android Studio React Native project using OpenCV to be built with AppCenter.
I'm working on a mac. Because an agent (mac OSX in my case) will be provisioned for me to build my project in the cloud, all the code and static libraries dependencies should come from the source repository. AFAIK I can't use find_package() in my case because of this serverless environment, right?
I've downloaded the OpenCV Android SDK which contains everything I need to link with the static libraries.
My problem is that I need the OpenCV static libraries to be properly ordered for the link phase to complete. I can't find a complete properly ordered list of those libraries. But I found a way to tell the linker to figure it out.
Here is where I am so far. First the CMakeLists.txt file:
cmake_minimum_required(VERSION 3.4.1)
# CMAKE_SOURCE_DIR : this is the directory which contains the top-level CMakeLists.txt, i.e. the top level source directory. In this case the andoid/app folder.
# set OpenCV Static Libraries Environment Variables
#set(OpenCV_STATIC_LIBS_DIR ${CMAKE_HOME_DIRECTORY}/src/opencv/staticlibs/${ANDROID_ABI})
#set(OpenCV_STATIC_3RDPARTY_LIBS_DIR ${CMAKE_HOME_DIRECTORY}/src/opencv/3rdparty/libs/${ANDROID_ABI})

Basically, it finds nothing :( I've tried removing
-Wl, --start-group ... -Wl,--endgroup
to only include the libraries and the result is the same.
Next is the output of the failed build (link part only):

What is wrong with this approach? Thanks for your help.
