title: How to set a number of parallel jobs for make in Cmake QtCreator project?
body: <p>My project is managed by CMake and I use QtCreator as a main IDE.
  I want to make QtCreator run <code>make -j number_here</code> command when it launches a build task to speed it up, but I am unable to find a corresponding configuration in QtCreator's project settings UI. I became somewhat lost in all it's settings.</p>
  
  <p>Should I modify <code>CMakeLists.txt</code> file somehow or is it configurable from the QtCreator's UI?</p>
