我如何使用cmake --build建立多个目标 [英] How can I build multiple targets using cmake --build

问题描述

我有一个CMake构建，其中包含许多不同的目标 A ， B ， C 等。
外部应用程序负责构建，并且当前通过调用

I have a CMake build with a bunch of different targets A, B, C, etc. An external application is tasked with building, and currently does so by calling

cmake --build .

但是，这会构建 all 个目标，有时我只想构建一个子集，例如 A 和 B ，但不是 C 。
-target 标志只能给出一次，并且只能接受一个目标。

However, this builds all targets, and sometimes I only want to build a subset, like A and B but not C. The --target flag can only be given once, and only accepts a single target.

我想我可以让CMake生成适当的Makefile，然后显式调用 make AB ，但这带走了 cmake --build 与构建系统无关。

I guess I could let CMake generate the appropriate Makefile, and then call make A B explicitly, but that takes away the nice thing about cmake --build being build system agnostic.

是否有解决此问题的好方法？

Is there a nice way to solve this?

推荐答案

CMake版本3.15添加了对此功能的支持。只需在命令行上列出所有目标，如下所示：

CMake version 3.15 added support for this feature. Simply list all targets on the command line as follows:

cmake --build . --target Library1 Library2
