I am new to C++ and OpenCV and I am stuck on this problem. I am using VS Code version 1.68.1 and when I try to run a main.cpp file, I always get this error:
main.cpp:2:10: fatal error: opencv2/opencv.hpp: No such file or directory
2 | #include "opencv2/opencv.hpp"
| ^~~~~~~~~~~~~~~~~~~~
This is the main.cpp code:
#include <stdio.h>
#include "opencv2/opencv.hpp"
using namespace cv;
int main(int argc, char** argv )
{
Mat image;
image = imread("lenna.jpg");
if ( !image.data )
{
printf("No image data \n");
return -1;
}
namedWindow("Display Image", WINDOW_AUTOSIZE );
imshow("Display Image", image);
waitKey(0);
return 0;
}
My CMakelists.txt file:
cmake_minimum_required(VERSION 3.0.0)
project(opencvTest)
include(CTest)
enable_testing()
set("OpenCV_DIR" "C:\\opencv4")
find_package( OpenCV REQUIRED )
include_directories( ${OpenCV_INCLUDE_DIRS} )
add_executable(opencvTest main.cpp)
target_link_libraries(opencvTest ${OpenCV_LIBS} )

What I noticed is that the definitions of the header point to this location for some reason
path being run but all my header files are in the opencv4 location. I do not know what to do about this and I have spent the last couple of hours trying to find a solution. Any help would be appreciated.
