title: Qt Creator creates both a debug and a release folder inside the designated debug folder
body: <p>I am using the default build directory in Qt Creator which is something like <strong>build-project-blah-blah-Debug</strong>. However, when I build my app in debug mode both a <strong>debug</strong> and and a <strong>release</strong> folder are created inside. If I set the build directory as <strong>build-project-blah-blah</strong> for both the debug and release builds Qt Creator does not behave properly, i.e. it complaints and it does not clean the built files.</p>
