Sorry that I'm late to this thread. Can you perhaps explain what you mean
by cascading dependencies in this instance, or what you are trying to do
exactly that is not supported?

In terms of output files that build script reads, yes that is possible -
the file just needs to be in the standard .d format that gcc produces and
then ninja can use that to track file dependencies. The script
"call-sphinx-build.py" does this, for example, and doc/guides/meson.build
tells meson/ninja to look for dependencies in file ".html.d" generated by
that script.
