Yes, it may be possible for Ninja.

Perhaps, but after regenerating the project the build tool will not
re-load the build files and start building again.  That will take
an additional invocation.  The number of iterations required is
bounded only by the depth of dependency chains.

It may be much easier to pack all this inside a separate
configure/build process using ExternalProject.
