Summary0013792: REGEX REPLACE fails if () capture is empty
Descriptionstring(REGEX REPLACE) fails for certain patterns with 'matched an empty string' error if a capture grood is empty, even if the full match is non-empty.
Steps To Reproduceset(input foo)
string(REGEX REPLACE "^([^.]*)(\\..*)?$" "\\1" output ${input})
Additional InformationCMake is correctly matching the regular expression (as can be seen by examining the captures), and the overall pattern (which is the old text to be replaced) is non-empty, so there should be no problem. (Even more interestingly, while the above pattern triggers the problem, other patterns which one might expect to tickle the same glitch do not.)
