CMake自定义生成步骤预链接/预生成不起作用

PRE_链接和PRE_构建在linux上的CMake中似乎不起作用（生成MakeFiles）。文档中说，只支持预构建。但是，PRE_LINK根本不起作用

我不确定是否理解错了，或者我是否遗漏了什么

（目前，作为解决方案，我在其上添加了一个假目标和后期构建步骤。然后创建依赖项就起作用了。但是，它也有自己的问题。对于我的设置，当并行生成（-j）完成时，它会产生问题

示例代码：

cmake_minimum_required(VERSION 2.8.5)
project(custom_command_test)

add_custom_target(my_actual_target
    COMMAND echo " I am the actual taget "
    COMMENT "Running actual target"
    )
add_custom_command(
    TARGET my_actual_target
    PRE_LINK
    COMMAND echo "I am prelinked to actual target"
    COMMENT " Running PRELINK action "
    )
add_custom_command(
    TARGET my_actual_target
    PRE_BUILD
    COMMAND echo " I am prebuilt to actual target"
    COMMENT " Running PRE_BUILD action"
    )
add_custom_command(
    TARGET my_actual_target
    POST_BUILD
    COMMAND echo " I postbuild to actual target"
    COMMENT " Running POST BUILD action "
    )

输出：

此问题的任何解决方案都类似于

PRE\u LINK

仅适用于“真实”目标，如库或可执行文件：

add_library(my_actual_target foo.cpp)

add_custom_command(
    TARGET my_actual_target
    PRE_LINK
    COMMAND echo "I am prelinked to actual target"
    COMMENT " Running PRE_LINK action "
    )
add_custom_command(
    TARGET my_actual_target
    PRE_BUILD
    COMMAND echo " I am prebuilt to actual target"
    COMMENT " Running PRE_BUILD action"
    )
add_custom_command(
    TARGET my_actual_target
    POST_BUILD
    COMMAND echo " I postbuild to actual target"
    COMMENT " Running POST_BUILD action "
    )

结果:

Running PRE_BUILD action
...
Running PRE_LINK action
...
Running POST_BUILD action

我知道这是文档问题

但是在实际目标之前运行PRE_LINK/PRE_BUILD命令怎么样？在我上面的示例中，PRE_BUILD是在实际目标之后生成/运行的。看起来你是对的！！这被认为是文档问题。下面是错误报告：
