CMake中的find_软件包（Boost）将Boost 1.75检测为Boost 1.77

我最近使用git存储库将我的Boost安装升级到Boost 1.75。现在，当运行

find_package（Boost）

时，它总是告诉我它找到了boost1.77.0。这是CMake中的错误还是Boost（或我自己的代码）中的错误 全输出：

您确定

find_package（Boost）

找到的是您的Boost安装，而不是其他安装吗

find_包

缓存其结果，因此升级Boost后，您需要清理项目的生成目录（或者至少从中删除

cmakcache.txt

文件）。你做到了吗？我在本地安装了Boost 1.76，在

/opt/

中安装了1.75，因此我很确定它不会检测到任何其他内容。此外，1.77仅在git上被标记，但尚未发布，而且cmake在删除CMakeCache和CmakeFiles后仍能找到它。请在cmake处理

find_包（Boost）时显示（添加到问题帖子）cmake生成的确切输出

@Tsyvarev:添加了outputRun

cmake

，带有附加选项

-DBoost\u DEBUG=ON

，因此它将打印更多有关搜索Boost的消息。其中一条消息应该包含

version.hpp

头文件的位置，CMake将其用于提取Boost版本。检查，该标题的路径是否合理。该头文件可以将版本定义为

BOOST\u version

或

BOOST\u LIB\u version

宏的值。该宏的值是多少？
