CMake graphviz自动生成 [英] CMake graphviz auto generated

问题描述

我知道通过CLI生成CMake项目依赖关系图的常用方法：

I know the common way to generate a CMake project dependencies graph by the CLI:

cmake --graphviz=[file]

但是有一种方法可以通过仅在CMakeList中设置标志或命令来自动生成它？这个想法是让CMakeLists.txt本身触发图形生成，而不是通过命令行触发用户。

But is there a way for it to be autogenerated by just setting a flag or command within a CMakeList? The idea is for the CMakeLists.txt itself to trigger the graph generation, and not the user through command line.

推荐答案

再次在脚本中调用CMake，例如像这样：

You could call CMake inside your script again, e.g. like:

add_custom_target(graphviz ALL
                  "${CMAKE_COMMAND}" "--graphviz=foo" .
                  WORKING_DIRECTORY "${CMAKE_BINARY_DIR}")
