// Uncomment and set to compile time level with zero cost (default is INFO).
// Macros like SPDLOG_DEBUG(..), SPDLOG_INFO(..) will expand to empty statements if not enabled

// Uncomment (and change if desired) macro to use for function names.
// This is compiler dependent.
// __PRETTY_FUNCTION__ might be nicer in clang/gcc, and __FUNCTION__ in msvc.
// Defaults to __FUNCTION__ (should work on all compilers) if not defined.
