libjpeg.lib was created with an older compiler than other objects in project ARWrapper

[snowymo]

Project ARvideo is a dependent project to project ARWrapper. There are two libjpeg.lib in win64-x64 and win32-i386 folder. Also I made one by my own through source jpeg-6b.

First I build ARvideo

1. I used the libjpeg.lib in lib/win64-x64. It successfully built.
2. I used the libjpeg.lib in lib/win32-i386. So many unresolved external errors.
3. I used the one made by my own. Also unresolved external symbols showed up.

Then I build ARWrapper

1. It said the libjpeg.lib is built by an old compiler
2. and 3) ended up as the same unresolved external symbols.

One thing I changed is, use extern "C" {#include <jpeglib.h>} instead of #include <jpeglib.h> for *.cpp file which include the header because libjpeg is a c library.
