Building Problem: A dependent dll was not found

Dear all,

I just started my work with ORBBEC camera with windows 10 system. I run both AstraSDK samples (e.g. SimpleBodyViewer-SFML) and the Hello World tutorial but there are some ambiguities. Hoping to get some help from you.

There is no error when building SimpleBodyViewer-SFML\main.cpp. However, the output window shows

'SimpleBodyViewer-SFML.exe' (Win32): Loaded 'C:\Windows\SysWOW64\ntdll.dll'. Cannot find or open the PDB file.
'SimpleBodyViewer-SFML.exe' (Win32): Loaded 'C:\Windows\SysWOW64\kernel32.dll'. Cannot find or open the PDB file.
'SimpleBodyViewer-SFML.exe' (Win32): Loaded 'C:\Windows\SysWOW64\KernelBase.dll'. Cannot find or open the PDB file.
'SimpleBodyViewer-SFML.exe' (Win32): Loaded 'C:\Windows\SysWOW64\sysfer.dll'. Cannot find or open the PDB file.
...

In terms of the Hello World, the outputs are same and, in addition, a window pops up (The screenshot is attached). I tried the first step and the codes are

#include <astra/astra.hpp>

#include <cstdio>
#include <iostream>

int main(int argc, char** argv)
{
   astra::initialize();

   // what will go here? you'll find out soon!

   astra::terminate();

   std::cout << "hit enter to exit program" << std::endl;
   std::cin.get();

   return 0;
}

Looking forward to your reply. Thank you very much.

Best regards,
Gwanbou
