Thanks for the reminder!

cereal-1.3.0 seems to be missing cmake config file, but it was present in 1.2.2. Is this a bug in conan recipe?
I think it is removed by this line in recipe:
tools.rmdir(os.path.join(self.package_folder, "share"))
It wasn't present in 1.2.2 recipe, why was it added?

@stilgarpl Please have a look here https://github.com/conan-io/conan-center-index/wiki/FAQ#why-are-cmake-findconfig-files-and-pkg-config-files-not-packaged

[stilgarpl]

@Croydon But without those config files, how to use imported targets for packages? Some packages have more than one and conan find_package generator can't handle that.

@stilgarpl Could you open a new issue to discuss about it, this PR is finished. Also, could you include more details, like the targets.
