问题描述

在package-Config.cmake中,如果我执行find_package而不是find_dependency,对我的应用程序会有什么影响?

In package-Config.cmake, if I do find_package instead of find_dependency, what would be the effect on my application? In what scenarios it will break?

推荐答案

根据, find_dependency 只是 find_package

如果找不到依赖项,它将设置一条信息性诊断消息并调用 return()结束对调用程序包配置文件的处理,并返回到 find_package()命令加载该文件。

If the dependency could not be found it sets an informative diagnostic message and calls return() to end processing of the calling package configuration file and return to the find_package() command that loaded it.

如果要使用,例如 find_package(REQUIRED)而不是 find_dependency ,并且找不到该包,那么用户将很难理解,该错误与外部包有关,而不仅与内部包有关。另外,如果 find_package 的外部调用不使用 REQUIRE 选项,则使用该选项执行内部调用是不一致的。

If you would use, e.g., find_package(REQUIRED) instead of find_dependency, and the package won't be found, then it will be difficult for user to understand, that the error is related with outer package, not only with the inner one. Also, if outer call of find_package doesn't use REQUIRE option, it is inconsistent to perform inner call with that option.
