Build fails on latest version of esp-idf

[playduck]

Running make menuconfig and subsequently make on this cloned repository using the latest esp-idf version (commit 39f090a) does not successfully build the project.

The following include headers are deprecated:

• rom/ets_sys.h -> esp32/rom/ets_sys.h
• esp_intr.h -> esp_intr_alloc.h
• rom/gpio.h -> esp32/rom/gpio.h
• rom/rtc.h -> esp32/rom/rtc.h
• esp_intr.h -> esp_intr_alloc.h

However the actual compilation is terminated by numerous counts of the following Error:

In file included from /fastLED-idf/components/FastLED-idf/include/FastLED.h:58,
                 from /fastLED-idf/components/FastLED-idf/FastLED.cpp:2:

        ^~~~

Removing -Wall and -Werror=all from /esp-idf/make/project.mk at line 370 lets the errors be treated as warnings and thus the compilation succeeds. However doing so isn't really addressing the underlying problem and probably pretty stupid.

it worked perfect until last ESP-IDF update, now I get endless bootloop,

Rebooting...

latest idf_v4.1-dev-1757-g826b9f6-dirty build

Despite all odds: It's working fine with idf 4.0.1 (the currently latest supported version on PlatformIO). I corrected the memmove warnings by exlicit casts.
