Is there some how to know the most suitable OpenCV version for ROS Melodic/Ubuntu 18 and fix it? I have installed 3.2.0

Hi,

I installed today the VS Code ROS extension, in order to try to debug my code for a ROS node for RGB-D Odometry using OpenCV, which is generating segmentation error (core dumped) when running. I made several changes followed by catkin_make yesterday, until I decided to try a debugger. The only change I made today was to config the ROS extension, as per this tutorial.

After some unsuccessful trials to find the issue with the debugger, I tried to make one change in my code, and build again. And I am now having the following error:

-- +++ processing catkin package: 'test_opencv_pkg'
-- ==> add_subdirectory(test_opencv_pkg)
-- Could NOT find OpenCV (missing: OpenCV_DIR)
-- Could not find the required component 'OpenCV'. The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found.
CMake Error at /opt/ros/melodic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
  Could not find a package configuration file provided by "OpenCV" with any
  of the following names:

  Add the installation prefix of "OpenCV" to CMAKE_PREFIX_PATH or set
  "OpenCV_DIR" to a directory containing one of the above files.  If "OpenCV"
  provides a separate development package or SDK, be sure it has been
  installed.

...
Makefile:754: recipe for target 'cmake_check_build_system' failed
make: *** [cmake_check_build_system] Error 1

I could not understand very well by the error log what can be done for fixing it. Appreciate if some can help to fix it.

Thanks.

Edit:

Adding CMakeLists.txt from my OpenCV Package. I could also notice that after trying build/debug with the mentioned VS Code stuff, I now have lots of new folders/files inside the package folder, such as "catkin", "catkin_generated", "test_results", "CMakeCache.txt", "CTestConfiguration.ini"...
