默认在CMake中构建自定义目标 [英] Build custom target by default in CMake
问题描述
我想使用cmake运行自定义命令。这听起来像是一个非常简单的任务/问题,但令人沮丧的是找到一个例子很困难。
I'd like to run a custom command with cmake. That sounds like an incredibly simple task/question, but it's frustrating how difficult it is to find an example.
这就是我正在尝试做的事情:
Here's what I'm attempting to do:
$ cmake .
$ make
> Hello World! (Output)
在Gnu中非常简单:
bar:
echo Hello World!
但是我想用cmake做到这一点。根据我一直在阅读的内容,应该可以使用下面的 CMakeLists.txt
文件做到这一点:
But I'm trying to do this in cmake. Based on what I've been reading, I should be able to do that with the CMakeLists.txt
file below:
cmake_minimum_required(VERSION 3.6)
project(foo)
add_custom_target(bar)
add_custom_command(
TARGET bar
COMMAND "echo Hello World!"
)
当前,如果我打电话给我 make
。我需要显式调用 make bar
。如何在全部
食谱中添加 bar
?
Currently there is no work to do if I just call make
. I need to explicitly call make bar
. How can I add bar
to the all
recipe?
我尝试添加 add_dependency(foo bar)
,但是 foo
是不存在的目标。如果有一些我不知道的超级目标,那将是完美的。然后,我可以将其用作我的自定义命令的目标,而不必担心 bar
。
I've tried adding add_dependency(foo bar)
, but foo
is a non-existent target. If there is some super-target that I'm unaware of that would be perfect. Then I could just use that as the TARGET for my custom command and not bother with bar
.
推荐答案
使用 ALL
选项默认情况下构建目标 :
Use ALL
option for build the target by default:
add_custom_target(bar ALL)
