Done.

I don't know. That seems like a lot of magic and bound to break existing 
code.

 get_property(loc TARGET myexe PROPERTY LOCATION)
 file(WRITE "some_script.bat" "./${loc}")

KDE4 does this:

 get_target_property(_executable ${_target_NAME} LOCATION )
 set_target_properties(${_target_NAME} PROPERTIES WRAPPER_SCRIPT 
   ${_executable})

and the WRAPPER_SCRIPT is used elsewhere.

Steve.
