英文:
Is it possible to generate a Kotlin .def file from a CMake library?
问题
我有一个现有的CMake项目，用于构建本地库（支持几个Linux平台以及Windows）。这个库将很快集成到一个Kotlin应用程序中，为此我需要创建一个.def文件，如此处所述
从概念上讲，我可以使用FILE和其他本地CMake工具来创建这个文件，但如果有一种“正规”的方法来做这件事，我更愿意使用那种方法！
英文:
I have an existing CMake project which is used to build a native library (supporting a few Linux platforms as well as Windows). This library will soon be integrated into a Kotlin app, for which I need to create a .def file, as stated here
Conceptually, I could create this using FILE and other native CMake tools, but if there's a "proper" way to do this, I'd prefer to use that!

那个文件是你必须亲自编写的吗？我无法仅从文档中阅读就能确定，但这是我的印象。如果每个.def对应于一个CMake目标，你可以通过使用add_custom_command的构建事件签名来创建一个构建事件自定义命令来运行cinterop命令。
如果你想要脚本化编写.def文件的过程，使其更自动化且对将来的重命名更具鲁棒性，
至于将目标编译选项之类的内容放在一个文件中，你可以使用$<TARGET_GENEX_EVAL:>和$<TARGET_PROPERTY:>生成器表达式以及COMPILE_OPTIONS目标属性和CMAKE_CXX_FLAGS（以及类似的）变量在file(GENERATE)命令调用中。
对于编译定义，可以使用COMPILE_DEFINITIONS目标属性。
有关所有支持的目标属性的列表，请参见https://cmake.org/cmake/help/latest/manual/cmake-properties.7.html#properties-on-targets
英文:
Is that file something you have to write yourself? I can't tell just from reading the docs, but that's the impression I'm getting. If each .def corresponds to a CMake target, you could create a build event custom command by using the build events signature of add_custom_command to run the cinterop command.
If you want to script the process of writing the .def file so it's more automatically-robust to you renaming things in the future,
As for putting things like target compile options in a file, you could use the $<TARGET_GENEX_EVAL:> and $<TARGET_PROPERTY:> generator expressions and the COMPILE_OPTIONS target property and the CMAKE_CXX_FLAGS (and similar) variables in a file(GENERATE) command call.
Simliar for compile definitions (see the COMPILE_DEFINITIONS target property).
