A linker error of SDL2 when I use vcpkg and VisualStudio

Question

I am using vcpkg and Visual Studio 2017, operating system is Windows 10 2004.
After I ran vcpkg install sdl2 in terminal, I created a project in VS2017.
I typed

#include "SDL2/SDL.h"
#include <stdio.h>

const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;

int main(int argc, char* args[])
{
    SDL_Window* window = NULL;
    SDL_Surface* screenSurface = NULL;
    if (SDL_Init(SDL_INIT_VIDEO) < 0)
    {
        printf("SDL could not initialize! SDL_Error: %s\n", SDL_GetError());
    }
    else
    {
        window = SDL_CreateWindow("SDL Tutorial", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, SCREEN_WIDTH, SCREEN_HEIGHT, SDL_WINDOW_SHOWN);
        if (window == NULL)
        {
            printf("Window could not be created! SDL_Error: %s\n", SDL_GetError());
        }
        else
        {
            screenSurface = SDL_GetWindowSurface(window);
            SDL_FillRect(screenSurface, NULL, SDL_MapRGB(screenSurface->format, 0xFF, 0xFF, 0xFF));
            SDL_UpdateWindowSurface(window);
            SDL_Delay(2000);
        }
    }
    SDL_DestroyWindow(window);
    SDL_Quit();
    return 0;
}

Then I switched solution platforms from X64 to X86 in order that I can use this package, because vcpkg didn't install X64 package. After clicking Local Windows Debugger, an error happened.

LNK2019 unresolved external symbol _main referenced in function "int __cdecl invoke_main(void)" (?invoke_main@@YAHXZ) MSVCRTD.lib(exe_main.obj)
