Compilation error when running make on Ubuntu 20.04, undefined reference to `cvLoadImage'

[Anchor1566]

Description:
I'm facing an issue while trying to compile a project using make on an Ubuntu 20.04 system with OpenCV version 3.2.6. The project is related to ROS and specifically the turtlebot3_slam_ws workspace.

The following error messages are shown during the compilation process:

/usr/bin/ld: /home/xun/Desktop/code/ros/turtlebot3_slam_ws/devel/.private/darknet_ros/lib/libdarknet_ros_lib.so: undefined reference to `cvLoadImage'
/usr/bin/ld: /home/xun/Desktop/code/ros/turtlebot3_slam_ws/devel/.private/darknet_ros/lib/libdarknet_ros_lib.so: undefined reference to `cvSaveImage'
collect2: error: ld returned 1 exit status
make[2]: *** [CMakeFiles/darknet_ros.dir/build.make:237: /home/xun/Desktop/code/ros/turtlebot3_slam_ws/devel/.private/darknet_ros/lib/darknet_ros/darknet_ros] Error 1
make[1]: *** [CMakeFiles/Makefile2:1384: CMakeFiles/darknet_ros.dir/all] Error 2
make: *** [Makefile:146: all] Error 2

System information:

• Operating system: Ubuntu 20.04
• OpenCV version: 3.2.6
• ROS version: noetic
• Compiler: make

Any help or suggestions on how to resolve this issue would be greatly appreciated.
