There has been a while since I last worked with openCV on Windows and when I decided to compile a project today I found out that QtCreator has permission denied when accessing the folder containing the dll's of openCV. The awkward thing is that it compiled fine for the first time and after the second time it started giving me the permission denied error. I am able to compile through terminal, but I have to type de entire command and I'm getting tired of it. I've tryed to change permissions to the opencv/bin folder and the qtCreator.exe program, but nothing has seemed to work. What is going on?
