Library dependency (PlatformIO, ESP32) fatal error: WiFiClientSecure.h: No such file or directory

[Mir1001]

Basic examples produce compiling errors (WiFiClientSecure.h: No such file or directory etc.) on ESP32 using PlatformIO.

To overcome this, I had to add additional include statements in main.cpp file.

#ifdef ESP32  
#include <SPIFFS.h>  //add   
#include <HTTPClient.h> //add  
#include <SD.h> //add  
#include <WiFi.h>  
#else
