rebuild一个target，总会引起他依赖的target也rebuild

[Wzshun]

Xmake 版本

2.8.1

操作系统版本和架构

windows10

描述问题

重新构建一个target，他依赖的target也会触发重新编译。这在某些大的顶层target，不可忍受重新编译的时长。

期待的结果

只重建我指定的target，在依赖项的target没被改动过的前提下。

Title: rebuild a target, it will always cause the target it depends on to rebuild

Xmake version

2.8.1

OS version and architecture

windows10

Describe the problem

Rebuild a target, and the targets it depends on will also trigger recompilation. For some large top-level targets, the recompilation time is unbearable.

Expected results

Only rebuild the target I specify, provided that the target of the dependency has not been changed.

Project configuration

none

目前只能全局 rebuild，要做成 target 粒度 rebuild 需要做部分重构，可能得费点时间

At present, only the global rebuild is possible. To achieve a target granular rebuild, partial refactoring is required, which may take some time.

改了下，再试试

xmake update -s dev

[waruqi]

默认行为不变，还是会自动重建所有依赖

xmake -r target

如果仅仅 rebuild 当前指定的 target，加 --shallow 参数

xmake -r --shallow target

我已经 merge 到 dev 了。
