根因分析
下载的存档哈希与 FetchContent_Declare 中指定的期望哈希不匹配，表明下载损坏、中间人攻击或期望哈希已过时。
English
The downloaded archive's hash does not match the expected hash specified in FetchContent_Declare, indicating a corrupted download, a man-in-the-middle attack, or an outdated expected hash.
官方文档
https://cmake.org/cmake/help/latest/module/FetchContent.html解决方案
-
删除缓存的下载：rm -rf build/_deps/<name>-src 然后重新配置以强制重新下载。
-
将 FetchContent_Declare 中的期望哈希更新为官方来源的正确哈希，然后清除缓存。
无效尝试
常见但无效的做法:
-
60% 失败
FetchContent caches the corrupted archive; need to delete the _deps directory first.
-
80% 失败
May accept a malicious or corrupted file; always verify the hash from a trusted source.
