Failed to compile (collect issue) with latest ESP32 core (undefined reference to `mDashInit')

[0x0fe]

1. Find Arduino's esp32 plaform.txt file and change it like in PR4209
2. Find library.properties file in the installed mDash library, and remove line ldflags=-lmDash
3. Restart Arduino IDE

So these steps have been followed, adapting since plastform.txt has changed, IDE restarted, but the issue persists.

The IDE is 1.8.19 and i tested with two version of the ESP32 core : 2.0 and the current master branch. In both cases it fails at the collect step.

[cpq]

Please try the latest version - tested and works with Arduino 1.8.19
