CMake reruns multiple times #1005

Open lifflander opened 4 years ago

lifflander commented 4 years ago

Describe the bug CMake has to run multiple times due to something in our configuration. Identify this problem and see if we can solve it.

Also, this might be related, the git sha is generated by CMake into a header file that is included for printing at startup. But, this means that CMake has to re-run if anything happens to git (even a local change). I'm not sure how useful this feature is. Maybe we can get the git status outside of cmake?

@lifflander I just checked and that's right. It looks like the code for getting git information intentionally causes configure to re-run. I don't think that's needed so I can probably find a way around it

@nmm0 Hey, are you still working on this? Does the PR you opened (https://github.com/DARMA-tasking/vt/pull/1144) do anything useful?
