When a regular expression match is used, CMake fills in CMAKE_MATCH_<n> variables with the match contents. The CMAKE_MATCH_COUNT variable holds the number of match expressions when these are filled.

On non-Windows hosts, any path that begins with a tilde ( ~ ) evaluates to true. Comparisons ¶ if (<variable|string> MATCHES regex) True if the given string or variable's value matches the given regular expression. See Regex Specification for regex format. New in version 3.9: () groups are captured in CMAKE_MATCH_<n> variables.

Feb 06, 2022 · 1 CMake does not support character classes in regular expressions; you need to use the character group with the same meaning. Furthermore I'm not sure why you add a capturing group that matches only a single string. if ($ {exename} MATCHES "^ (xxx) [A-Za-z0-9_]+") ... Note that this matches strings starting with xxx, not strings with xxx anywhere.
