VS_MOBILE_EXTENSIONS - missing PropertySheets in vcxproj

[lipov3cz3k]

Hi, when I turn on VS_MOBILE_EXTENSIONS_VERSION cmake correctly generates ImportGroup element with ExtensionSDKLocation for WindowsMobile. This works fine and Extension shows up in Visual Studio, but I cannot include any of header file from this SDK extension.
If I remove extension in VS and add it back, then all includes works. I noticed that vcxproj has slight difference - Cmake generated file does not have PropertySheet with SDKExtensionDirectoryRoot.
See cmake-generated.vcxproj.txt and VS-generated.vcxproj.txt

Maybe I did something wrong, but there is no "SDKExtensionDirectoryRoot" string in cmake sources, so I guess it can't work anyway.
