ci: enable compilation with "-Werror" During the conversion of our CI scripts in bf418f09c (ci: refactor unix ci build/test scripts, 2018-07-14), we accidentally dropped the "-DENABLE_WERROR=ON" switch in our cmake invocation. Re-add it to help us catch compiler warnings early. (cherry picked from commit 900846571905cf7a9530d2680c627fde6044db92)
