Install a CMake macro script from within a python package install script (using setup.py)

Question

So I have a Python package – it’s all set up on PyPI, and on GitHub, no problem. This is something I’m relatively familiar with.

What is unknown to me is: the notion of installing a CMake script as part of the python package install process. The python package in question is a development tool – you use it to preprocess some of your C/C++/Obj-C/Obj-C++ source files and generate some predefined macros in a header – and it works well when it’s wrapped in a CMake macro (for example like so) and executed as part of a proper chain of dependencies.

For one, I am not sure how to approach this, as there seem to be significant differences between the setuptools sandbox stance and distutils’ willing systems-level installer integration – and then even if I did know how to go about setting things up correctly in setup.py, I can’t find a good precedent on where a CMake script pertaining to a Python package might live.

All thoughts and insights on the matter are welcome.

我花了一段时间才明白你的问题。如果我理解正确，你要做的是在cmake的标准安装位置提供IodSymbolize.cmake，以便依赖你的软件（symbolizer）的其他用户/项目可以在他们的构建过程中使用它。我认为你正朝着一个好的方向思考，试图为你的软件包的最终用户提供服务。好问题！

以下是我对cmake世界中事物如何运作的理解。

假设我是想要使用“symbolizer”可执行文件的最终用户。我要做的是 find_package（符号化）。这将尝试找出可执行文件的位置，并设置可在构建过程中使用的某些变量。

您需要提供Findsymbolizer.cmake文件。

请查看：http://www.cmake.org/Wiki/CMake:How_To_Find_Libraries

如果你是Unix / Linux平台，还要查看/ usr / / share / cmake / Modules目录中提供的Find * .cmake文件。

Findsymbolizer.cmake文件正常工作后，将其发送到cmake邮件列表进行审核。一旦被接受，它可以打包在cmake的下一个版本中。然后你的模块可用于cmake。希望我回答你的问题。如果您需要更多信息，请更新。
