Kdevelop steps and breakpoints not working

Question

I need to use steps (Step over, Step over instruction ...) and breakpoints.

But options Step over, Step over instruction and ect. disabled in the Run menu.

And when I put a breakpoint in the program, the program does not stop at that breakpoint.

I found that I have to disable compiler and linker optimizations. But I do not know how to disable optimization in Kdevelop 4.4.1.

Where can I find this setting? Or is the cause of the problem with steps and breakpoints not compiler optimization?

. toolchain ? CMake? , CMAKE_BUILD_TYPE Debug.
