Error while executing make on mydumper - c++

I'm trying to install mydumper but the make step complains about undefine symbols. I've searched other questions where they talk about linking your object file to make sure the compiler can find the methods it needs. However this is just plain installation and I am not a C guy. Any pointer is highly appreciated. Here's the error I am seeing:

SDL2 is not linking anymore on macOS Big Sur (M1)

I have created a small C++ SDL2 project with CMake under macOS Big Sur (m1).
This is the CMakeLists.txt:
cmake_minimum_required(VERSION 3.22.2)
project(sdl2gamepad)
add_library(sdl2lib SHARED IMPORTED)
set_property(TARGET sdl2lib PROPERTY IMPORTED_LOCATION "/opt/homebrew/lib/libSDL2.dylib")
include_directories("/opt/homebrew/include")
add_executable(${PROJECT_NAME} main.cpp)
target_link_libraries(${PROJECT_NAME} PRIVATE ${sdl2lib})
I installed SDL2 and CMake with homebrew.
The project was initially compiled and linked with the Makefile without problems and I was able to run it.
I then wanted to structure my project with an src and build folder and had adapted the CMakeLists.txt. Unfortunately, CMake/Make was no longer able to link the SDL2 lib.
Linking error message:
[ 50%] Linking CXX executable sdl2gamepad

make[2]: *** [sdl2gamepad] Error 1
make[1]: *** [CMakeFiles/sdl2gamepad.dir/all] Error 2
make: *** [all] Error 2
I then reset the CMakeLists.txt to the status where it had worked (code above). But unfortunately, the problem still exists.
But I can compile the code with this command, it is probably due to a CMake misconfiguration.
$ clang++ main.cpp -o main /opt/homebrew/lib/libSDL2.dylib -I /opt/homebrew/include
CMake Version is 3.22.2.
SDL2 Version is 2.0.20.
Many thanks for your help!

Unable to build my-sql-connector-c++ with CMake

Introduction
I am trying to connect and interact with a mysql db running on my local, in a c++ project. I am also using cmake to compile my project.
Preparation
I installed mysqlconnector cpp by using mysql-connector-odbc-8.0.25-macos11-x86-64bit.dmg from their community downloads. I have the include and lib files available at /usr/local/mysql-connector-c+
CmakeLists.txt
Part of my CMakeLists.txt which deals with mysqlconnector is referenced below:
cmake_minimum_required(VERSION 3.13.4 FATAL_ERROR)
set(CMAKE_CXX_STANDARD 11)
set(FULL_PATH_TO_MYSQL_CONNECTOR_CPP_DIR "/usr/local/mysql-connector-c++")
include_directories(${FULL_PATH_TO_MYSQL_CONNECTOR_CPP_DIR}/include)
link_directories(${FULL_PATH_TO_MYSQL_CONNECTOR_CPP_DIR}/lib64)
add_executable(runservice main.cpp)
target_link_libraries(runservice mysqlcppconn)
The cmake command runs fine.
Build Error
When I try to build using '''make``` command, I get the following error :
Undefined symbols for architecture x86_64:
"mysqlx::abi2::r0::common::Value::print(std::__1::basic_ostream<char, std::__1::char_traits<char> >&) const", referenced from:

NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.

I can't understand this error or how to go about solving this.
Thank you for your precious time

Does anyone know how to fix the problem.
Many thanks
I don't know the exact reason that this happens, but I have applied a patch to makefiles and config.mk from MacPort. You can download them in plaintext and use patch Makefile < make.diff and patch config.mk < config.diff to apply the patch.
patch files
I had to change /usr/lib/zathura/pdf.dylib to /usr/lib/zathura/pdf.so after the make install in order to make zathura display pdf files.

DisplayImage.cpp errors Using OpenCV with gcc and CMake

I've had issues in compiling DisplayImage.cpp, I've followed the tutorial here and to create a cmake file and generate executables, however, when I was compiling the problem with make it displays the following errors:

I am running MacOS could anyone please help!
Thanks
Try adding
#include <opencv2/highgui/highgui_c.h>
to the top of DisplayImage.cpp code. Then compile and execute again.
Hope it works! I just tried and verified it myself now.
