Hi
AFAICS the only real problem is the EXE_EXTENSION. If you use a target
name in add_custom_command, CMake will figure out the location and name
of the actual executable on its own. By appending EXE_EXTENSION CMake
won't be able to recognize the target name any more, and just run the
command as you specified it. In this case you would need to fiddle
around with CMAKE_CFG_INTDIR, that's true. But since CMake is able to do
it automagically, I think you shouldn't try to outsmart it.
Another thing: I think you should use CMAKE_RUNTIME_OUTPUT_DIRECTORY
instead of CMAKE_LIBRARY_OUTPUT_DIRECTORY.
My 2c...
