是否可以将导入的库添加到target_link_libraries，以便处理包含目录？ [英] Possible to add an imported library to target_link_libraries that takes care of include directories too?

问题描述

我不知何故我正在努力找出是否可能在CMake中定义一个导入的库，指定目标属性（include_directories和库路径），并希望CMake将附加include目录一旦我将该项目添加到target_link_libraries在另一个项目。

somehow I am struggling with finding out whether it is possible to define an imported library in CMake, specifying target properties (include_directories and library path) and hoping that CMake will append the include directories once I add that project to target_link_libraries in another project.

假设我在一个名为Module-Conf.cmake的文件中有一个导入的库：

Let's say I have an imported library in a file called Module-Conf.cmake:

add_library(mymodule STATIC IMPORTED)
set_target_properties(mymodule PROPERTIES IMPORTED_LOCATION "${OUTPUT_DIR}/lib")
set_target_properties(mymodule PROPERTIES INCLUDE_DIRECTORIES "${OUTPUT_DIR}/include")

在项目中，我添加了依赖：

And in a project I add the dependency:

include(Module-Conf)
target_link_libraries(${PROJECT_NAME} mymodule)

CMake会将include_directories属性附加到包含路径吗？现在我看不到路径，所以似乎我必须通过使用get_target_property自己做它。

Will CMake append the include_directories property to the include path? Right now I cannot see the path so it seems that I have to do it by myself by using get_target_property?

问题：我可以做一些CMake魔法来自动附加include到另一个项目的include目录？

Question: Can I do some CMake magic to automatically append the include to the include directories of another project?

非常感谢。

Thanks a lot. Martin

推荐答案

INCLUDE_DIRECTORIES INTERFACE_INCLUDE_DIRECTORIES 属性是传输性。

改为设置 INTERFACE_INCLUDE_DIRECTORIES 。
