将列表传递给 CMake 宏 [英] Passing a list to a CMake macro

问题描述

我正在尝试编写一个通过给定库列表的宏.然而，宏中的消息调用仅打印列表的第一项.我在这里做错了什么?

I am trying to write a macro which goes through a given list of libraries. However the message call in the macro prints only the first item of the list. What am I doing wrong here?

代码:

    macro( FindLibs LIBRARY_NAMES_LIST )
        message( "inside ${LIBRARY_NAMES_LIST}" )
    endmacro()

    set( LIBRARY_NAMES_LIST lib1 lib2 lib3)
    message( "outside ${LIBRARY_NAMES_LIST}" )
    FindLibs(${LIBRARY_NAMES_LIST})

输出:

message( "outside lib1 lib2 lib3" )
message( "inside lib1" )

推荐答案

在将变量传递给宏时引用它:

Quote the variable as you pass it to the macro:

FindLibs("${LIBRARY_NAMES_LIST}")
