Install opencv 4.0 with eclipse on Windows- Error during Build

Hello All,

I have installed opencv4.0 on windows. I am compiling OPENCV using CMAKE, I have configured and generated successfully in CMAKE. When i am building using mingw32-make its throwing errors. Can anyone help me in building successfully.

Below is the error which i am facing when i build with an command mingw32-make:
