I see an alternative.
If you really want to rebuild all your project
each time you build
you may afford to relaunch
CMake each time too don't you?

so
1) Do out-of-source build
2) Each time you want to build again
     2a) delete your build tree
     2b) re-create root build dir
     2c) launch cmake then make in your pristine build tree.
