将库链接到cmake项目中的所有目标 [英] link library to all targets in cmake project
问题描述
让我描述一下我认为是足够普遍的用例，应该予以支持。考虑一个项目，该项目由一个库和一组使用该库的可执行文件组成。一种简单的方法是add_library，然后是一系列add_executable（）target_link_lib（）对。
Let me describe what I think is a sufficiently common use case, that it should be supported. Consider a project which consists of a library and a set of executable that use that library. A straightforward approach is to add_library, followed by a sequence of add_executable() target_link_lib() pairs.
这是很多样板代码。能够执行set（PROJECT_LINK_LIBS，lib1 ...）这样的事情，并让cmake删除多余的样板，这将是很好的。
This is a lot of boilerplate coding. It would be nice to able to do something like set(PROJECT_LINK_LIBS, lib1 ...), and have cmake remove the extra boilerplate.
进一步考虑这一点，我意识到我想要一个link_libraries函数，其功能类似于include_directories。我会认为：
Thinking on this more, I realize I would like a link_libraries function that behaves similarly to include_directories. I would argue that this:
- 在很多情况下都会有用。
- 会导致来鼓吹CMakeLists。
- 将鼓励更好的代码组织-自然地有动机去组织文件夹，代码和可执行文件，使得所有可执行文件都具有相同的依赖关系-
有这样的东西吗？
推荐答案
如 https://stackoverflow.com/a/50295894/129550 所述现在，请求的 link_libraries（示例example2）函数实际上是cmake的一部分。
As mentioned at https://stackoverflow.com/a/50295894/129550 the requested link_libraries(example example2) function is actually now a part of cmake.
