Coverage tool for cmake

Usage
1

Hello,

We have a lot of lines of code in cmake, maintained by multiple teams. I was wondering if there is some kind of a coverage tool for cmake itself, which helps to identify dead code.

Thanks

IMHO: this is not realy needed.

pip install gcovr

see for config file example gcovr.cfg

Thanks for the reply.

I was just wondering if there are tools to identify dead cmake code and prevents code rot. I think it will be useful in some cases.

Thanks for the link, it’s useful.

Maybe I was not being clear enough, just like there is gcov for C/C++, coverage.py for python, jacoco for java, I was wondering if there is such a tool for cmake language.

There isn’t. I suppose one could be built out of --trace or --trace-expand output though. However, results over all configurations of interest would really be needed to avoid removing Windows support code because only coverage from Linux is considered.

thanks for the response, even just for linux, it could be useful. Just an idea.
