Hi Kris,
I have done that by following:
1) use Ninja Generator;
2) include empty "rerun.cmake" file, I put this file into binary dir, so I need
a patch;
3) add a patch to Ninja Generator to correctly write dependencies for
"build.ninja" from included cmake files, if cmake file is in the binary
directory;
4) add a custom commands that check the new files and touching "rerun.cmake"
file;
5) once "rerun.cmake" file is touched ninja will rerun cmake;
Best regards,
Sergey
