Building CXX object router/src/mock_server/src/CMakeFiles/mock_server.dir/x_mock_session.cc.o
/net/atum07/export/home/didrik/gitclone/trunk-add-executable/router/src/mock_server/src/x_mock_session.cc:27:10: fatal error: google/protobuf/util/json_util.h: No such file or directory
 #include <google/protobuf/util/json_util.h>

How to repeat:
cat /etc/os-release 
NAME="Oracle Linux Server"
VERSION="7.6"
ID="ol"
VARIANT="Server"

cmake <path> -DWITH_PROTOBUF=system

Suggested fix:
json_util.h can be found in protobuf 3.0 so raise version check
