Can't debug in QT creator with cmake project

Question

I created a new Plain C++ Project with CMake Build. When I set a breakpoint and press the Debug Button I get this message:

This does not seem to be a "Debug" build.
Setting breakpoints by file name and line number may fail.

You can add this CMake argument to your Build Settings:

-DCMAKE_BUILD_TYPE=Debug
