I compiled a package that requires Ceres (find_package(Ceres) in its CMakeLists.txt). Using version 1.11.0~dfsg0-2 I hit the issue describe in this bug while when using version 1.11.0~dfsg0-2ubuntu0.1, installed from xenial-proposed, Ceres is found and the compilation goes through.
This package fixes the bug for me.
[Tested]
1.11.0~ dfsg0-2ubuntu0. 1
