Of course you could put that in a CMake script and execute it with e.g. 
'${CMAKE_COMMAND} -p ${CMAKE_CURRENT_SOURCE_DIR}/get_date.cmake' in a 
custom command :-). Then it would truly be the compile date. (Needless 
to say, the script would need to write the date into some generated 
source file, e.g. with configure_file.)
