How big is this lib? Can we avoid using this and just weak link the CLSID?
Specially now that you added the Win7 version check.

[nhu, 2013/04/10 09:46:42]

On my windows kits, it is 504KB. If we don't use it, the linker will fail with
undefined reference CLSID error.

[sail, 2013/04/10 17:00:10]

Unfortunately that's too big.

I think you can fix the link error by adding the library that contains the
sensor API to the DelayLoadDLLs section.

Worst case we should just hardcode the CLSID.
