catkin_make not working after VS Code ROS extension debug setup

edit

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:

    OpenCVConfig.cmake
    opencv-config.cmake

  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.
Call Stack (most recent call first):
  test_opencv_pkg/CMakeLists.txt:5 (find_package)


-- Configuring incomplete, errors occurred!
...
Makefile:754: recipe for target 'cmake_check_build_system' failed
make: *** [cmake_check_build_system] Error 1
Invoking "make cmake_check_build_system" failed

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"...
