Using cmake with nginx

I'm speaking about manual vs automatic source-level dependency handling.
For example, CORE_DEPS is an easy but inaccurate cross-platform hack. The
same is true for ADDON_DEPS: if you add any header here, all addons will be
rebuilt on that header change.
That's not a big deal, because C compiles fast enough and ccache could be
used to mitigate "false positives" of hand-written deps. But there's room
for improvement for sure.
For example, I had build issues because of forgetting to include headers
into core/addon deps after splitting addon into a set of header/source
files.

Targeting any modern C-oriented build system would add many benefits
including "standardized" routines for library detection, dependency
handling, etc.
Are there any plans on adding "per-addon header deps" so changes to a
single header don't result in all addons recompiling?
