JSON_SKIP_LIBRARY_VERSION_CHECK
#define JSON_SKIP_LIBRARY_VERSION_CHECK
When defined, the library will not create a compiler warning when a different version of the library was already included.
Default definition
By default, the macro is not defined.
#undef JSON_SKIP_LIBRARY_VERSION_CHECK
Notes
ABI compatibility
Mixing different library versions in the same code can be a problem as the different versions may not be ABI compatible.
Examples
Example: switch off the version check
The code below switches off the warning about including a different version of the library.
#define JSON_SKIP_LIBRARY_VERSION_CHECK 1
#include <nlohmann/json.hpp>
...
Example: warning about a different library version
The following warning will be shown in case a different version of the library was already included:
Already included a different version of the library!
