I'd like to use this in my PlatformIO project.

[idolpx]

I can get everything to compile to the liblwip_open.a file but can't seem to find where I need to put it to have it compiled into my firmware. I tried replacing the liblwip_gcc.a in the ".platformio/packages/framework-arduinoespressif8266/tools/sdk/lib" folder. (This liblwip_open.a is much smaller for some reason.) . But that didn't work. I've been searching but have not found a solution yet.

Any help would be greatly appreciated.
