如何使用 CMAKE_EXPORT_COMPILE_COMMANDS?
我一直在尝试将 clang-modernize 与 CMAKE_EXPORT_COMPILE_COMMANDS 结合使用，如在此工具的帮助中推荐的那样.
I've been trying to use clang-modernize with CMAKE_EXPORT_COMPILE_COMMANDS as recommended in the help of this tool.
使用此选项，cmake 会生成一个包含编译信息的 JSON 文件，例如包含路径(另见).
With this option cmake generates a JSON file containing compile info like include paths (see also).
这个变量在cmake的命令行中被接受，但是 cmake --help-variable CMAKE_EXPORT_COMPILE_COMMANDS 不起作用(这与 此邮件列表发布).
This variable is accepted on the command line of cmake,
but cmake --help-variable CMAKE_EXPORT_COMPILE_COMMANDS doesn't work (which is coherent with this mailing list posting).
有人知道如何使用它吗?
Has someone any idea on how to use it?
我也可以将它与 cppcheck 一起使用.
I could also use it with cppcheck.
更多信息
我在 clang 开发者论坛 指出此 cmake 功能并非在所有生成器上都可用.这在未来可能会改变，同时我的问题仍然存在，我也会尝试看看如果我使用 Visual Studio 以外的其他生成器会发生什么.
I've discovered on a clang developer forum that this cmake feature is not available on all generators. This might change in the future, in the mean time my question remains and I will try too see what happen if I use other generators than Visual Studio.
推荐答案
