title: Run Command after generation step in CMake
body: <p>I have a command line tool that should be run after CMake created my .sln-file. Is there any way to do that using CMake?</p>
  
  <p>Using execute_process(COMMAND ..) at the end of the CMakeLists.txt does not help because this is executed after the Configure step, however, the .sln-file is created in the generation step.</p>
  
  <p>Thanks a lot!</p>
