@madebr Where did you find these names?

In glog master branch:

• config file is glog-config.cmake: https://github.com/google/glog/blob/0a2e5931bd5ff22fd3bf8999eb8ce776f159cda6/CMakeLists.txt#L835
• "config" imported target is glog::glog: https://github.com/google/glog/blob/0a2e5931bd5ff22fd3bf8999eb8ce776f159cda6/CMakeLists.txt#L846

I don't see any official module file for glog.

@SpaceIm
Indeed, I was wrong.
I just checked google for cmake find glob and combinations with find and config.
Thanks for rectifying.

This might mean that some dependency on glog will break.
I don't know remember which one exactly it was..

[SpaceIm]

There are only 2 recipes depending on glog in CCI: folly and ceres-solver

[madebr]

Thanks, then I'll have to search in projects.

folly recipe works fine if lowercase cmake name is restored (this why I came here :p #2363 (comment)). Didn't check ceres-solver with glog enabled.
