CMake错误“找不到目标向其添加属性” [英] CMake error "Can not find target to add properties to"

问题描述

在我的CMakeLIsts.txt文件中，我这样写：

In my CMakeLIsts.txt file I write this:

set(LIBHELLO_SRC hello.c)
set_target_properties(hello_static PROPERTIES OUTPUT_NAME "hello")
get_target_property(OUTPUT_VALUE hello_static OUTPUT_NAME)
message(STATUS "This is the hello_static OUTPUT_NAME:"${OUTPUT_VALUE})

当我运行 cmake 时，它显示错误消息：

When I run cmake, it shows the error message:

set_target_properties Can not find target to add properties to: hello_static

推荐答案

要使代码正常工作， hello_static 必须是CMake目标的名称；通过 add_executable添加的内容 或例如code> add_library 命令。

For your code to work, hello_static must be the name of a CMake target; something which is added via the add_executable or add_library commands for example.

这与您的项目名称无关。

This is unrelated to the name of your project.

似乎您缺少以下内容：

add_library(hello_static ${LIBHELLO_SRC})

将直接放置在

set(LIBHELLO_SRC hello.c)
