In the CMakeLists.txt file add an OPTION command that will be available 
on windows:

IF(WIN32)
   OPTION(MYPROJ_BUILD_FOR_WINCE "Enable to build WinCE support." OFF)
ENDIF(WIN32)
# ... code common to all builds ...
IF(MYPROJ_BUILD_FOR_WINCE)
   # ... code specific to WinCE
ELSE(MYPROJ_BUILD_FOR_WINCE)
   # ... code for non-WinCE builds
ENDIF(MYPROJ_BUILD_FOR_WINCE)

Then the option can be set in the CMakeSetup configuration dialog or on 
the cmake command line:

cmake -DMYPROJ_BUILD_FOR_WINCE:BOOL=ON -G "NMake Makefiles" ../MySrc

CMake is not designed to generate Makefiles with make-time options like 
this.
