Hi,
I understand that you are getting an error that says, 'Projects\Build Matlab Generated Image Processing Libraries\processImagesVCC.lib: No such file or directory exists'. There could be an issue with the linker not finding the generated .lib file, or possibly that the file isn't being generated at all.
Verify MinGW installation and configuration properly, and Run mex -setup and mex -setup C++ in MATLAB to ensure that MinGW is selected as the default compiler for both C and C++ and ensure that your MinGW is up to date.
I hope this helps.
