[Cmake] SET_SOURCE_FILES_PROPERTIES and nmake command line flag order

[William A. Hoffman]

1.  PROPERTIES is required, and if ommited this following error should be produced:

this->SetError("called with illegal arguments, maybe missing a PROPERTIES specifier?");

2. It is usually not a good idea to mix release and debug on windows as the run time
libraries are not compatible.   And the compile flags put library link information
into the .obj files.   I am not sure if it is an ordering problem.   You could see
if you can get it to work from the MS GUI by changing the order.  If that works you could do
something like this:

# save the standard cxx flags
   SET(SAVE_CXX_FLAGS ${CMAKE_CXX_FLAGS})
# set the standard flags to nothing
   SET(CMAKE_CXX_FLAGS )
# set all the files compile flags to the standard
   FOREACH source
     SET_SOURCE_FILES_PROPERTIES(vil_bicub_interp+byte-.cxx COMPILE_FLAGS ${SAVE_CXX_FLAGS})
# now override the ones for the file 
   SET_SOURCE_FILES_PROPERTIES(vil_bicub_interp+byte-.cxx COMPILE_FLAGS -Od)
