Are we forced to use the cmake and idf.py based build for compiling applications using stable 4.0 ?

I am more used to the old makefile style and want to migrate the code to 4.0.
Is it possible to use the makefile based build on 4.0 ?

Yes, the GNU Make build system is still supported in ESP-IDF v4.x as the "legacy" build system for ESP32. We haven't yet announced when support will be dropped, but it won't be before ESP-IDF v5.0.

Relevant docs are here:
