     @@ Commit message
      
          This commit fixes one of the TODOs listed in the CMakeLists.txt.
      
     -    There's also some small fix to ensure it builds successfully.
     +    As pcre2 doesn't provide cmake find module, we find it with pkgconf.
     +    This patch also works with vcpkg on Windows, with pkgconf and pcre2
     +    installed.
     +
     +    Pkgconf and pcre2 is detected automatically just like curl, expat
     +    and iconv. The output of CMake indicates whether pcre2 is found.
