In jsoncpp-namspaced-targets.cmake, it creates JsonCpp::JsonCpp imported library without first checking whether it was already created by former call to find_package(JsonCpp). As CMake allows repeated call to find_package(), the error of "another target with the same name already exists" should be fixed.
