CMake build gives undefined reference to functions in OpenCV - c++

Question

I'm making a jump from python to C++ in vscode. My project utilizes OpenCV and I quickly ran into a lot of problems with trying to get my compiler (mingw-w64) and CMake to find and reference the OpenCV functions.
My test code looks like this. I know I have to change my file path, but when I do I get the same problem.
#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "iostream"
using namespace cv;
using namespace std;
int main( int argc, char** argv )
{
Mat image1,image2;
// Read the file
image1 = imread("C:\\Users\\arjun\\Desktop\\opencv-logo.jpg");
// Check for invalid input
if(! image1.data )
{
cout << "Could not open or find the image" << std::endl ;
return -1;
}
//Write the File
imwrite( "C:\\Users\\arjun\\Desktop\\opencv-logo-new.jpg",image1);
// Read the Writen File
image2 =imread("C:\\Users\\arjun\\Desktop\\opencv-logo-new.jpg");
namedWindow("Image1");
imshow("Image1",image1);
namedWindow("Image2");
imshow("Image2",image2);
waitKey(0);
}
My CMakeLists.txt looks like this
cmake_minimum_required(VERSION 3.0.0)
project(chessbot VERSION 0.1.0)
include(CTest)
enable_testing()
find_package( OpenCV REQUIRED)
include_directories( ${OpenCV_INCLUDE_DIRS} )
add_executable(chessbot main.cpp)
target_link_libraries(chessbot ${OpenCV_LIBS})
set(CPACK_PROJECT_NAME ${PROJECT_NAME})
set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
include(CPack)
When I use the CMake Build tool (which I believe is supposed to make my executable for me) I get a bunch of undefined references to opencv functions

There is another compile tool that doesn't return undefined references and seems to compile just fine, which leads me to believe that CMake cant find the target library for some reason. The learning curve is steep for me. Can someone explain to me the issue? Why cant I reference the OpenCV functions?
