Hi, How can I check if the user supplied value is a valid positive integer or not?
I have tried the following, but it is not entering the if condition, what might be wrong? Is there a better solution? SET(MY_NUMBER "100" CACHE STRING " Please enter the number") string(REGEX MATCH "^[1-9][0-9]*$" MY_NUMBER ${MY_NUMBER}) if(MY_NUMBER) #This area is not getting executed, whats wrong here endif() Thanks, Lloyd
