  -DBUILD_YOLO_LIB=ON \
  -DBUILD_YOLO_TENSORRT=ON \
  -DBUILD_ASYNC_DETECTOR=ON \
  -DBUILD_CARS_COUNTING=ON

I am encountering the following error:-

CMake Error at CMakeLists.txt:37 (FIND_PACKAGE):
  By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "OpenCV", but
  CMake did not find one.

  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.

I have installed cv2 using the command pip install opencv-python==4.12.0.88, I am encountering the same error.

While running the command make -j, I encountered the following error:-

make: *** No targets specified and no makefile found. Stop.

Hello!
pip install opencv-python==4.12.0.88
This code used for install OpenCV for Python. But this is a C++ project and for it do you need a main C++ OpenCV library.
