Visual Studio "fatal error LNK1104: cannot open file"未使用或包含的库

Visual Studio "fatal error LNK1104: cannot open file" on a library that is not used or include

本文关键字：未使用 file open 包含 cannot fatal Studio error LNK1104 Visual 更新时间：2023-10-16

我有UnitTest项目，而不是使用我自己的NeuralNetwork库项目，该项目使用我自己的Boost项目(我用Boost.vcxproj重建 boost(，UnitTest不使用 Boost。那么，为什么我的UnitTest项目尝试链接libboost_serialization-vc142-mt-x64-1_71.lib？

我检查，除了包含 .hpp 文件的文件夹外，我的UnitTests.vcxproj中没有提升引用。我的Boost项目和NeuralNetwork项目构建没有任何错误，并正确处理了Boost.lib和NeuralNetwork.lib。

我添加了一个命令来忽略主CMakeLists.txt的库，它工作得很好。
