I've seen that list(LENGTH) will ignore empty elements in a list. Example: 1;2;;4;5
Length will be 4 here instead of 5. I was trying to come up with a way to modify the list as a string prior to iterating it to give empty elements some dummy value, so that the above example would appear as: 1;2;<empty>;4;5 However, this isn't going to work with string( REGEX REPLACE ) as the modifications are not included in the continuation of the regex search (I think positive lookbehind is needed here?). Basically this case cannot be converted: ;;; to: <empty>;<empty>;<empty> Anyone know how I can iterate empty elements in a list? -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
