Re-run if the input file changes or if the output file is removed. This only works with the Makefile generators currently. The limitation of the Ninja generator is tracked as issue #15256. The IDE generators will need larger refactoring as they currently rely on being able to determine the depends and output files at the start of generate-time, which is too early for the file(GENERATE) case.
