cmake：获取add_library（）名称

本文介绍了cmake：获取add_library（）名称的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

是否可以获取所有 add_library（）调用的名称？例如，

Is there a way to get the names of all add_library() calls? E.g.

add_library(lib1
  some.cpp
)

add_library(lib2
  some.cpp
)

add_library(lib3
  some.cpp
)

# And then somehow get in a variable MY_LIBRARIES_NAMES = lib1 lib2 lib3

有没有做过的cmake调用或变量？（如果感兴趣，我对cmake 2.8版感兴趣）

Is there any cmake call or variable that does that? (I am interested in cmake version 2.8 if it matters)

谢谢！

推荐答案

在较新版本的CMake（> =版本3.7）中，该版本为目录属性：

In newer versions of CMake (>= version 3.7) that would be the BUILDSYSTEM_TARGETS directory property:

get_directory_property(MY_LIBRARIES_NAMES BUILDSYSTEM_TARGETS)

对于较旧版本的CMake，您可以覆盖 add_library（）调用以收集目标列表：

For older versions of CMake you could overwrite the add_library() call to collect a list of targets:

macro(add_library _target)
    _add_library(${_target} ${ARGN})
    set_property(GLOBAL APPEND PROPERTY GlobalTargetList ${_target})
endmacro()

...

get_property(_allTargets GLOBAL PROPERTY GlobalTargetList)
message(STATUS "GlobalTargetList: ${_allTargets}")
