ESP8266WiFi.h: No such file or directory

How can I make the WifiManager library work on a ESP32 board? I'm using PlatformIO to develop my code.

Here are my imports:

#include "esp_camera.h"
#include <Arduino.h>
#include <WiFiClientSecure.h>
#include <PubSubClient.h>
#include <ArduinoJson.h>
#include <EEPROM.h>
#include <WiFiManager.h>
WiFiClient espClient;
PubSubClient client(espClient);
WiFiManager wifiManager;

platformio.ini

[env:esp32cam]
platform = espressif32
board = esp32cam
framework = arduino
monitor_speed = 115200
build_flags = -DMQTT_MAX_PACKET_SIZE=36000
lib_deps = espressif/esp32-camera@^1.0.0 knolleary/PubSubClient@^2.8 bblanchon/ArduinoJson@^6.18.5 tzapu/WiFiManager@^0.16.0

But when I run the code, I get this following error:

.pio\libdeps\esp32cam\WiFiManager/WiFiManager.h:16:25: fatal error: ESP8266WiFi.h: No such file or directory

After further research, I see that WiFiManager uses ESP8266WiFi.h and now I'm wondering how I can make this library work on my ESP32 or is there an alternative library? The project's readme does say it works on ESP32.

The latest release of WiFiManager library (0.16) is almost a year old and doesn't support ESP32.
You will need to install the library from Github to get ESP32 support.

In your platformio.ini replace

tzapu/WiFiManager@^0.16.0

with
