I noticed that the size of the Project/.pio/build directories can vary significantly between a esp8266 project and a esp32 based project.
esp8266 (modwifi): 7 Mbytes
esp32 (esp-wrover-kit): 97 Mbytes
How come this difference?
In the esp32 .pio/build directory two directories are dominant:
17M ./esp-wrover-kit/libfb6 (Wifi)
Is there any way to avoid consuming this much disk space for every project, it seems not efficient?
