No launch directory when installed with apt

[rkoyama1623-2021]

はじめまして、本パッケージでは、いつもお世話になっております。なお日本語で失礼します。
本パッケージをaptコマンドでインストールを行うと、
Ubuntu18の場合、timed_roslaunch.launchがrospack find timed_roslauch直下に配置されますが、
Ubuntu16の場合、$(rospack find timed_roslauch)/launch以下に配置されます。

# ubuntu 18.04
sudo apt install ros-melodic-timed-roslaunch
ls $(rospack find timed_roslaunch)/timed_roslaunch.launch

# ubuntu 16.04
sudo apt install ros-kinetic-timed-roslaunch
ls $(rospack find timed_roslaunch)/launch/timed_roslaunch.launch

Ubuntu18では、 c335736 が反映されていないのではないかと推測しますが、今後反映される予定はあるでしょうか？
どうぞよろしくお願いいたします。

I confirm for ros-melodic.
Here is the content inside the package installed with apt: cmake package.xml timed_roslaunch.launch timed_roslaunch_test.launch
It works well by installing from the source.

@sebastienmascha, Thank you for your comment.
I meant the roslaunch directory (You are right, so I changed the issue title).
When we use this package across the different ros environment, current directory structure is inconvenient.
c335736 should generate roslaunch directory and put launch file in it, even if we use this package in melodic.
So, I want the author to update the apt package if possible.

This is definitely required, the apt needs to be updated to include the launch directory.

Temporary solution:

  <arg name="timed_roslaunch_dir" value="launch/" if="$(eval env('ROS_DISTRO')=='kinetic')"/>
  <arg name="timed_roslaunch_dir" value="" unless="$(eval env('ROS_DISTRO')=='kinetic')"/>
  <include file="$(find timed_roslaunch)/$(arg timed_roslaunch_dir)timed_roslaunch.launch">
    <arg name="time" value="5"/>
    <arg name="pkg" value="some_package"/>
    <arg name="file" value="something.launch"/>
  </include>
