To: Eric Noulard <eric.noul...@gmail.com>
Okay it seems to be perl problem therefore I've decided to make the
script directly calling system function:
Here you have an exemple using REGEXP extension:
MACRO (TODAY RESULT)
IF (WIN32)
EXECUTE_PROCESS(COMMAND "date" "/T" OUTPUT_VARIABLE ${RESULT})
string(REGEX REPLACE "(..)/(..)/..(..).*" "\\3\\2\\1"
${RESULT} ${${RESULT}})
ELSEIF(UNIX)
EXECUTE_PROCESS(COMMAND "date" "+%d/%m/%Y" OUTPUT_VARIABLE ${RESULT})
string(REGEX REPLACE "(..)/(..)/..(..).*" "\\3\\2\\1"
${RESULT} ${${RESULT}})
ELSE (WIN32)
MESSAGE(SEND_ERROR "date not implemented")
SET(${RESULT} 000000)
ENDIF (WIN32)
ENDMACRO (TODAY)
Hope it can be usefull to someone!
