[cmake-developers] [PATCH] WINCE, VS: Allow selecting an SDK for Windows CE on Visual Studio

With the current implementation I sent this seems to work and the SDK ends up in 
The generated vxproj files for try compile.

I'm also quite new to the whole Windows CE development but I try to explain what I figured out until now.

An example for a Windows CE 2013 (aka 8.0) SDK is the one for Ti AM335x from Adeneo [1].

Once installed it can be found under:
C:\Program Files (x86)\Windows CE Tools\SDKs\SDK_AM335X_SK_WEC2013
Where SDK_AM335X_SK_WEC2013 is the SDK name.

The content of SDK_AM335X_SK_WEC2013\sdk subfolder is similar in structure to a folder under:
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC

I don't know the exact details but it looks like it contains a complete VC compiler targeted at the specific board.

If I create a Project using this SDK in visual studio the following XML snippet ends up in the resulting .vxproj file:

<ProjectConfiguration Include="Debug|SDK_AM335X_SK_WEC2013">
      <Configuration>Debug</Configuration>
      <Platform>SDK_AM335X_SK_WEC2013 </Platform>
</ProjectConfiguration>

It seems like this is the way Windows knows what compiler to use based on the entries in:
HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows CE Tools\\SDKs

Where all the installed Windows CE SDKs are listed with the default key pointing to their path on the filesystem.

That's all I know till now ;)
