How could I extend new shaders for win8

I write new glsl shaders for iOS and Android, it work alright.
But when I port it to win8, I find cocos2d-x is using precompiled shader which pack the binary data into c++ header file, seems using bin2h or something like.
I want to know if I write a equation shader in hlsl version, how could I make it using in cocos2d-x?

Anyone has some idea about this question?

Also eager to get the answer on this. How to compile the GL shader to the header

Is there anyone know the solution?

cocos2dx\platform\third_party\winrt\angleproject\src\glslPrecompiler

You need switch to branch wp8-xaml of angleproject
