ENH: change the way #cmakedefine is changed to #undef, so it is similar to
what autoconf does. This makes porting software from autoconf to cmake easier, since it's easier to diff the resulting config headers. Now the following #cmakedefine HAVE_STRING_H 1 #cmakedefine HAVE_STRLCAT 1 produce: #define HAVE_STRING_H 1 /* #undef HAVE_STRLCAT */ whereas before they produced: #define HAVE_STRING_H 1 /* #undef HAVE_STRLCAT 1 */ Since it's commented out anyway, it's now change in behaviour.
