RP2040 Connect + WiFiWebServer build issues

Libraries
2

PlatformIO’s LDF includes a bunch of things in the build which seem wrong. If I use

[env:nanorp2040connect]
platform = raspberrypi
board = nanorp2040connect
framework = arduino
lib_deps = khoih-prog/WiFiWebServer@^1.4.0
lib_ignore =
   WiFi101
   WiFiEspAT
   WiFi
   ESP_AT_Lib

and adapt

to

#if !(ESP32 || ESP8266) && !defined(ARDUINO_NANO_RP2040_CONNECT)
  #include <avr/pgmspace.h>
  #define memccpy_P(dest, src, c, n) memccpy((dest), (src), (c), (n))
#endif

(file is locally in .pio\libdeps\nanorp2040connect\WiFiWebServer\src\WiFiWebServer.h), the WebServer example compiles

elf2uf2 ".pio\build\nanorp2040connect\firmware.elf" ".pio\build\nanorp2040connect\firmware.uf2"

Can you test whether that works?

When you build it with the Arduino IDE, do you use the Arduino core GitHub - earlephilhower/arduino-pico: Raspberry Pi Pico Arduino core, for all RP2040 boards or GitHub - arduino/ArduinoCore-mbed?
