Why is this failing ?
It only tries to build an executable, it doesn't run it.

Is the compiler called cl.exe or clarm.exe ?

You need to setup a "toolchain file" as described here:
http://www.cmake.org/Wiki/CMake_Cross_Compiling

It should contain
SET(CMAKE_SYSTEM_NAME Windows)
SET(CMAKE_C_COMPILER ...)
SET(CMAKE_CXX_COMPILER ...)

This should be enough to get you over the first steps so a hello world can be 
built.

Windows-cl.cmake assumes that cl is the native compiler and so can be only x86 
32bit or x86 64bit.
Either this file has to be modified or a new platform "WindowsMobile" is 
required. Is Windows Mobile a slimmed down version of XP or is it based on 
Win CE ?
