This was the only log priority missing.
#include <SDL2/SDL_log.h>
+#define LOGV(...) SDL_LogVerbose(SDL_LOG_CATEGORY_APPLICATION, __VA_ARGS__)
#define LOGD(...) SDL_LogDebug(SDL_LOG_CATEGORY_APPLICATION, __VA_ARGS__)
#define LOGI(...) SDL_LogInfo(SDL_LOG_CATEGORY_APPLICATION, __VA_ARGS__)
#define LOGW(...) SDL_LogWarn(SDL_LOG_CATEGORY_APPLICATION, __VA_ARGS__)
