[Noetic] flexbe_app fails to build: missing libraries

[sloretz]

The ROS Noetic release is failing to build on all platforms. It complains of missing libraries. Maybe there are dependencies not specified in the package.xml? #70 seems like it might be relevant.

Noetic had an old address for maintainer; I've updated and included myself in noetic (ROS 2 was already updated.)

@sloretz It appears that the nwjs folder is getting installed as binaries within Debian package. Normally we run an install script (rosrun flexbe_app nwjs_install) after building to download the relevant nwjs and install. The CI tests that we run do it this way. That will clearly have issues if install points to /opt/ros folder, so installing those libraries as part of binary makes sense, but I suspect that some nwjs dependency is not getting captured and installed. I'll dig into this

[dcconner]

@pschillinger Any thoughts on this as you handled the earlier (kinetic and before) releases ?

[pschillinger]

The binary jobs for flexbe_app also didn't properly run before, so we always had them excluded. Unfortunately, I don't have a lot of experience with this, but this old PR is where I left it after initially trying to release it: ros/rosdistro#19823. I hope this helps!

[dcconner]

Thanks. I missed that old issue. I will plan to keep flexbe_app out of releases for now. I'll revisit this later in fall after we work on the flexbe_webui more. I'll leave this open for now to document the issue.
