I will take the liberty to guess that your ROS1 and ROS2 new_msgs packages are used only for message generation (do not contain any headers and src files). In that case you can try the following:

ROS2 package.xml:

<?xml version="1.0"?>
<package format="3">
  <name>new_msgs</name>
  <version>0.0.1</version>
  <description>New message defined for ROS2</description>
  <maintainer email="cram3r95@gmail.com">root</maintainer>
  <license>Apache License 2.0</license>
  <author>CGH</author>

  <buildtool_depend>ament_cmake</buildtool_depend>

  <depend>std_msgs</depend>
  <depend>builtin_interfaces</depend>

  <build_depend>rosidl_default_generators</build_depend>
  <exec_depend>rosidl_default_runtime</exec_depend>

  <member_of_group>rosidl_interface_packages</member_of_group>

  <export>
    <build_type>ament_cmake</build_type>
  </export>
</package>


ROS2 CMakeLists.txt:

cmake_minimum_required(VERSION 3.5)
project(new_msgs)

# Default to C++14
if(NOT CMAKE_CXX_STANDARD)
  set(CMAKE_CXX_STANDARD 14)
endif()

if(CMAKE_COMPILER_IS_GNUCXX OR CMAKE_CXX_COMPILER_ID MATCHES "Clang")
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Wextra -Wpedantic")
endif()

# find dependencies
find_package(ament_cmake REQUIRED)
find_package(rosidl_default_generators REQUIRED)
find_package(std_msgs REQUIRED)
find_package(builtin_interfaces REQUIRED)

rosidl_generate_interfaces(new_msgs
  "msg/YoloObstacle.msg"
  "msg/YoloList.msg"
  "msg/Header.msg"
  DEPENDENCIES std_msgs builtin_interfaces
)

ROS1 package.xml:

<?xml version="1.0"?>
<package format="2">
  <name>new_msgs</name>
  <version>0.0.0</version>
  <description>The new_msgs package</description>

</package>


ROS1 CMakeLists.txt: cmake_minimum_required(VERSION 2.8.3) project(new_msgs)

find_package(catkin REQUIRED COMPONENTS
  sensor_msgs
  std_msgs
  message_generation
)

add_message_files(
   FILES
   Header.msg
   YoloList.msg
   YoloObstacle.msg
 )

generate_messages(
   DEPENDENCIES
   sensor_msgs
   std_msgs
 )

catkin_package(
CATKIN_DEPENDS message_runtime sensor_msgs std_msgs
)

include_directories(
  ${catkin_INCLUDE_DIRS}
)

Building the ros1_bridge from source is the more tricky part. Refer to the package documentation for that.
