My program depends on Microsoft redistribute package, or to be more specific, depends on MSVCR100.dll

A recommanded approach is to install the redistribute package before my program running. However, my program is quite small(about 1MB), the vcredist.exe is about 5MB, it is a little too big for my installer. 

So here is another way, according to license of Microsoft, we can install the dll into a subfolder(`\VC\redist\x86\Microsoft.VC100.CRT\`) in my application folder. So my application directory is like:

```
MyAppFolder\a.exe
MyAppFolder\lib\a.dll
MyAppFolder\VC\redist\x86\Microsoft.VC100.CRT\MSVCR100.dll

```

My question is, how do I make the a.dll find the MSVCR100.dll which located in another folder?
