fmtlog not working in constexpr function

[zcuder]

constexpr void log_custom() {
    constexpr char randomString[] = "Hello World";
    logi("A string, pointer, number, and float: '{}', {}, {}, {} {}", randomString);
}

编译报错
~/fmtlog/test/log_test.cc: In function ‘constexpr void log_custom()’:
~/fmtlog/test/../fmtlog.h:758:21: error: ‘logId’ declared ‘static’ in ‘constexpr’ function
758 | static uint32_t logId = 0;

看样子在constexpr函数内FMTLOG宏定义的logId不是constexpr变量而且是static的，有没有办法支持constexpr function?
