问题：
I'm wondering if there is a way to print out all accessible variables in CMake.我想知道是否有办法在 CMake 中打印出所有可访问的变量。 I'm not interested in the CMake variables - as in the --help-variables option.我对 CMake 变量不感兴趣——就像在--help-variables选项中一样。 I'm talking about my variables that I defined, or the variables defined by included scripts.我说的是我定义的变量，或者包含脚本定义的变量。
I'm currently including:我目前包括：
INCLUDE (${CMAKE_ROOT}/Modules/CMakeBackwardCompatibilityCXX.cmake)
And I was hoping that I could just print out all the variables that are here, instead of having to go through all the files and read what was available - I may find some variables I didn't know about that may be useful.我希望我可以打印出这里的所有变量，而不必浏览所有文件并阅读可用的内容 - 我可能会发现一些我不知道的变量可能有用。 It would be good to aid learning & discovery.帮助学习和发现会很好。 It is strictly for debugging/development.它严格用于调试/开发。
This is similar to the question in Print all local variables accessible to the current scope in Lua , but for CMake!这类似于打印 Lua 中当前作用域可访问的所有局部变量中的问题，但对于 CMake！
Has anyone done this?有没有人做过这个？
