Description

had some issues with operator"" _json namespacing. added the #define as per docs: https://json.nlohmann.me/api/operator_literal_json/ then there was an issue with #if JSON_USE_GLOBAL_UDLS not making any sense. should that be #ifdef ?

Reproduction steps

1. #define JSON_USE_GLOBAL_UDLS
2. #if JSON_USE_GLOBAL_UDLS causes compiler error

Expected vs. actual results

probaly should be #ifdef, not #if
