为什么引入依赖包要涉及到两个接口

[Entercat]

Is your feature request related to a problem? Please describe.

引入一个依赖包需要先使用add_require()，然后再使用add_package()，语义上有点重复。

Describe the solution you'd like

取消最开始的add_require()，只在每个target下使用add_package()

Title: Why introducing dependency packages involves two interfaces

[waruqi]

不重复，功能不同。。

1. add_requires 是全局接口，配置需要安装的包，已经每个包的具体特性、版本、static/shared, debug/release 等配置。
   配置了这个接口，仅用于告诉 xmake ，当前怎么安装包，不代表 target 就会去用它。

它类似于 cargo.toml 的配置

2. add_packages 是 target 粒度接口，会根据 add_requires 的包配置，对特定 target 关联绑定 links, includedirs 等实际编译链接所需要的信息。它是不包含包的配置信息的。

这个类似于 add_links/add_includedirs/add_frameworks/add_ldflags 的集合

完全不一样的东西，你要合并成一个接口，很多特性就要受到限制，并且每个 target 都要完整配置一长串的 包配置 ，很繁琐。。

No duplication, different functions. .

1. add_requires is a global interface that configures the packages that need to be installed, as well as the specific features, version, static/shared, debug/release, etc. of each package.
   Configuring this interface is only used to tell xmake how to install the package currently, but it does not mean that the target will use it.

It is similar to the configuration of cargo.toml

2. add_packages is a target granular interface, which will associate links, includedirs and other information required for actual compilation and linking to a specific target based on the package configuration of add_requires. It does not contain package configuration information.

This is a collection similar to add_links/add_includedirs/add_frameworks/add_ldflags

Completely different things. If you want to merge them into one interface, many features will be restricted, and each target must be fully configured with a long list of package configurations, which is very cumbersome. .
