LNK1104: 在 boost_python 版本为 1.72 时无法打开文件 'libboost_python27-vc142-mt-x64-1_71.lib'

Question

我正在使用 cmake 和 Visual Studio 2019 来构建我的项目。我的 boost 版本是 1.72，我在目录 boost_1_72_0\stage\lib 中生成了文件 libboost_python27-vc142-mt-x64-1_72.lib 和 b2.exe.

我用 cmake 生成了 .sln 文件。然后我在 Visual Studio 2019 年构建项目。但是，它以错误结束 LNK1104: cannot open file 'libboost_python27-vc142-mt-x64-1_71.lib'

我真的不明白为什么它要求 libboost_python 版本 1_71 而不是 1_72。我从未在任何文件中引入版本 1.71 请求。那么应该如何呢？我怎样才能让它发挥作用？

我现在知道原因了。在我的项目文件夹中还有另一个带有一些头文件的 boost 目录。我错误地包含了 boost 目录并依赖于 boost 1.71....
