Probably too late now and there isn't a bug filed so far as I know, but one thing I would love to see added to cmake is an append command so that lines like this:set(CMAKE_EXE_LINKER_FLAGS_RELEASE "${CMAKE_EXE_LINKER_FLAGS_RELEASE} /INCREMENTAL:NO") become shorter and easier to understand: append(CMAKE_EXE_LINKER_FLAGS_RELEASE "/INCREMENTAL:NO") The existing syntax for the set command is just ugly when appending. I know you can define a macro or function to do this but I just feel that it should be supported out of the box as it would make CMakeLists.txt files more readable.
Hi Glenn: I am changing the subject line to keep discussion out of the bugfix thread as requested by Dave. It appears what you want is the list APPEND command for blank-delimited strings. But then later someone will want to add other parts of the list functionality to blank-delimited strings as well such as removing items from the blank-delimited list. Until you have two parallel list systems, one for blank delimited strings and one for semicolon-delimited strings (i.e., the current lists). I think most would reject the idea of having two parallel list systems with different delimiters so here is one possibility. For now just stick to list functionality, e.g., list(APPEND CMAKE_EXE_LINKER_FLAGS_RELEASE "/INCREMENTAL:NO") and then change the semicolon delimiters to blanks using strings(REGEX REPLACE ...) once you have the list completely assembled. Of course, that will not work for the corner case where the strings contain semicolons. So in the long term, the right thing to do with lists might be to allow a choice of delimiter if you could do that in such a way as to preserve backwards compatibility.
