Subject: [PATCH] cmake: disable FMT_USE_TZSET for WIN32

otherwise we'd have following FTBFS with MinGW, like:

../src/fmt/include/fmt/chrono.h: In lambda function:
../src/fmt/include/fmt/chrono.h:952:5: error: '_tzset' was not declared
in this scope; did you mean 'tzset'?
  952 |     _tzset();
      |     ^~~~~~
      |     tzset
