Ctl-Alt-b does not work for .h files using cmake

Using qmake if you are looking at a .h file and do Ctl-Alt-b it will build the .cpp file with the same name as the  .h file.  Using cmake you get:  ninja: error: unknown target ..... etc

It would really be nice for qtcreator to work the same way for cmake as it does for qmake in this regard.
