<div class='commit-subject'>ENH:  Add cross compiling support in the GUI in the same dialog that prompts for<span class='decoration'></span></div><div class='commit-msg'>      the generator on the first configure.  It either ask for a toolchain file
      or asks for all the information a toolchain file might contain.

      Also added option for setting non-default compilers if not cross compiling.
      Fixes #6849.

      Also a bit of code cleanup and re-organizing.
