Use CPU_BASELINE / CPU_DISPATCH instead to disable optimizations. Example: -DCV_DISABLE_OPTIMIZATION=ON

@fengyuentau Could you take a look?

@fatalfeel Could you explain briefly why you want to build OpenCV in this way? Basically you are turning off every optimization in your cmake command.

in Eclipse I need in debug mode to see every variables content and set it when in debug mode
