了解如何显示使用某些C++ API的自定义构建时间警告

#define CUSTOM_WARNING(condition, message) \
    do { \
        if (!(condition)) { \
            #pragma message("WARNING: " message) \
        } \
    } while(0)

// 使用示例
CUSTOM_WARNING(defined(API_VERSION) && API_VERSION >= 2, "Using an outdated API version. Please update to API version 2 or later.")

#if !defined(API_VERSION) || API_VERSION < 2
#pragma message("WARNING: Using an outdated API version. Please update to API version 2 or later.")
#endif

#if !defined(API_VERSION) || API_VERSION < 2
#pragma warning(push)
#pragma warning(disable: 4068) // 禁用未知的 pragma 警告
#pragma message("WARNING: Using an outdated API version. Please update to API version 2 or later.")
#pragma warning(pop)
#endif
