[CMake] How to get the current date

[ycollette.nospam at free.fr]

Hello,

The version found in the archive doesn't works under windows XP 64 bits. So here is a little modified one (date seems to be a command from the cmd executable ...):

MACRO (TODAY RESULT)
    IF (WIN32)
        EXECUTE_PROCESS(COMMAND "cmd" " /C date /T" OUTPUT_VARIABLE ${RESULT})
        string(REGEX REPLACE "(..)/(..)/..(..).*" "\\1/\\2/\\3" ${RESULT} ${${RESULT}})
    ELSEIF(UNIX)
        EXECUTE_PROCESS(COMMAND "date" "+%d/%m/%Y" OUTPUT_VARIABLE ${RESULT})
        string(REGEX REPLACE "(..)/(..)/..(..).*" "\\1/\\2/\\3" ${RESULT} ${${RESULT}})
    ELSE (WIN32)
        MESSAGE(SEND_ERROR "date not implemented")
        SET(${RESULT} 000000)
    ENDIF (WIN32)
ENDMACRO (TODAY)

...

TODAY(RESULT)
message(STATUS "Compilation date = ${RESULT}")

CMake has no builtin for that but if you search the ML archive
http://www.cmake.org/Wiki/CMake_FAQ#Where_can_I_find_searchable_CMake_Mailing_Archives.3F
you'll find several discussions (and solution proposal) on this subject.
