Issue Description

Hi guys!

Currently, I'm trying to install the Ros2 Eloquent package within a Docker File. When Building, I get the following log:

--- stderr: realsense2_camera

   Intel RealSense SDK 2.0 is missing, please install it from https://github.com/IntelRealSense/librealsense/releases

  

I have already installed the SDK as stated in https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md . However, I keep getting that log. I don't know if the fact of it being a Docker Container affects the package building when executing the CMake.

I look for your response.

Hi @rafaelRinconFo As a starting point in investigating your problem, I note that you list librealsense version 2.16.5 from November 2018 as the librealsense SDK version that you are using. ROS wrapper versions should be matched as closely as possible with the librealsense version number listed on the Release Notes for a particular wrapper version.

https://github.com/IntelRealSense/realsense-ros/releases

The first version of the official ROS2 Eloquent wrapper began with a recommendation of SDK 2.38.1, and that is the current recommended version for ROS2 at the time of writing this.

Hi @MartyG-RealSense , is there any way to force the installation of a specific version of the SDK? I have already performed the sudo apt-get --only-upgrade install librealsense2-utils librealsense2-dkms command and sudo apt-get commands as recommended and the resulting log states that librealsense2-dkms and librealsense2-utils are already in the latest versions.

I hope that the link below will provide the guidance that you need for installing specific versions of packages. It recommends removing the currently installed SDK packages and then guides about how to install particularly-numbered packages:

I think the issue might be that librealsense2 2.38.1 is not yet available in the ros-distributions for eloquent. There is a merged PR for it but they have not released an update yet.
In the meanwhile, I think you'll have to install it separately, following the the librealsense2installation guide for linux it may find version 2.38.1 there.

Hi @rafaelRinconFo Do you still require assistance with this case, please? Thanks!
