CMAKE_uu如何评估调用CMAKE函数的当前行？

出于调试目的，如果我可以访问

脚本的文件名

脚本中的当前行号

在配置时间调用CMake函数/宏时。（我想通过包装器函数为我自己的组件自动注入这些信息，以跟踪缓存变量被覆盖的时间和位置）

而1。似乎正在评估CMAKE_当前的列表_文件，我不知道如何实现2。总是设置为它实际放置的行，在我的例子中是包装函数内的行

正如建议的那样，我可以在调用方站点上使用[CMAKE_CURRENT_LIST_LINE][3]作为附加参数来实现这一点。但我希望避免这种情况，以隐藏“公共接口”中的调试逻辑

一个简单的工作示例来表达我的需求：

CMakeLists.txt：

cmake_minimum_required(VERSION 3.0)
include( myComponent )

# access via public interface
myComponentFunctionWrapperFunction( "CMakeLists.txt:5" )
myComponentFunctionWrapperMacro( "CMakeLists.txt:6" )
myComponentMacroWrapperFunction( "CMakeLists.txt:7" )
myComponentMacroWrapperMacro( "CMakeLists.txt:8" )

# direct access of the hidden interface
myComponentFunction( ${CMAKE_CURRENT_LIST_FILE} ${CMAKE_CURRENT_LIST_LINE} "CMakeLists.txt:11" )
myComponentFunction( ${CMAKE_CURRENT_LIST_FILE} ${CMAKE_CURRENT_LIST_LINE} "CMakeLists.txt:12" )
myComponentMacro( ${CMAKE_CURRENT_LIST_FILE} ${CMAKE_CURRENT_LIST_LINE} "CMakeLists.txt:13" )
myComponentMacro( ${CMAKE_CURRENT_LIST_FILE} ${CMAKE_CURRENT_LIST_LINE} "CMakeLists.txt:14" )

# the actual component

function( myComponentFunction CALLER CALLER_LINE DATA )
    message( STATUS "myComponent.function( ${CALLER}, ${CALLER_LINE}, ${DATA} )" )
endfunction()

也许我可以通过某种方式访问堆栈跟踪？如果您发出消息（警告…），则行号可用。但我想存储它们，而不仅仅是在终端上打印。

有什么想法吗？

不确定这是否可行

我想通过包装器函数自动注入这些信息 让我自己的组件跟踪缓存变量在何时何地出现 覆盖）

您是否尝试过将cmake与--trace一起使用（如果您有足够新的cmake版本，甚至可以使用--trace expand）？这可能是一个更好的方式来实现你的目标
