Did I miss something?

There is no makefile with the arduino IDE/build system :-(

How does "the build system" you want to make it work with actually
work?  Is it incapable of "compiling" a "source file" into an
"object file" that happens to be a text using an arbitrary
"compiler"?

It looks for all *.ino files (which need to contain C code) in the specified ("project") directory and compiles and links them all into one blob, it adds a smidge of code at the beginning to run setup() followed by loop(). It then dumps this blob (via serial/USB) into the flash of the device that will run it.

it's a very dumbed down system, designed for non-programmers to do trivial things (blink a few LEDs, etc) that's been pushed to far more sophisticated uses than it was ever designed for.

I was hoping that readers are imaginative enough to replace Makefile
with whatever way things are normally built with when reading my
message, and the reader can just replace "source file" with
"config.h.sample", "compiler" with "test -f config.h || cat
config.h.sample >config.h" and "object file" with "config.h".
