据我所知,INTERFACE库就像Visual Studio属性表,非常有用.我们可以使用它来链接静态库并传播属性.

但IMPORTED目标让我困扰:我无法看到只能通过IMPORTED目标解决的问题.

我和CMake有一个奇怪的问题.

我正在将Curl导入到我的项目中,所以我为您编写了一个简单的CMakeLists.txt文件摘要.

ADD_LIBRARY(libcurl SHARED IMPORTED )

SET_PROPERTY(TARGET libcurl PROPERTY IMPORTED_LOCATION ../lib/libcurl.lib)

当我运行CMake时,它会为MS VC++生成项目文件(也适用于Linux).然后进入项目文件,我发现curl库(libcurl-NOTFOUND)的错误引用!

如果我将我的代码更改为静态导入:

ADD_LIBRARY(libcurl STATIC IMPORTED )

SET_PROPERTY(TARGET libcurl PROPERTY IMPORTED_LOCATION ../lib/libcurl.lib)

我找到了对../lib/libcurl.lib的正确引用.

你知道为什么会这样吗？

非常感谢你!

我正在用 c++ 编写项目，并且在 cmake 中导入库时遇到问题。正在导入的第三方库不会传播包含目录。
