When using a project (generated from CMAKE) is there an easy way to toggle between "Debug" and "Release"?

For instance, when using Visual Studio, there is a drop down window where you can easily pick which target you want.

For KDevelop, all I see are the instructions here https://stackoverflow.com/questions/15064715/kdevelop-with-cmake-project-how-to-manage-debug-and-release-builds which involve creating an entirely new build. If you do this, there is still no easy way to toggle debug and release (that I know of).

Am I wrong? Is there an easier way?

I don't think there's an easier way than clicking "Project -> Configure" and selecting your debug/release build dir. I agree maybe a dropdown would be nice ... having the two build dirs seems kind of normal to me, QtCreator does the same for example.
