These extensions help you snap ROS applications for the Noetic Ninjemys distribution using the content-sharing feature.
Note that this set of extensions are based on the ros1-noetic extension.
Therefore, they are applied on top of the ros1-noetic extension.
See ros1-noetic for more information.
This extension requires Snapcraft 8.x+.

What it does for the build-time environment
- Everything the
ros1-noeticextension does. - Adds a content plug mounting the provider snap content at
$SNAP/opt/ros/underlay_wsand defines a default provider. - Sets the
CMAKE_SYSTEM_PREFIX_PATHvariable to point at the mounted system path. - Adds the build snap providing the build-time equivalent of the default content-sharing provider snap to
ros-build-snaps.
This implies that you can avoid declaring as build-packages all the ROS packages that are found inside the ROS metapackage with the name corresponding to the extension used above.
What it does for the run-time environment
- Everything the
ros1-noeticextension does.
- Expands the runtime environment required by ROS th include the ROS workspace provided by the content-sharing snap. Similar to the typical chaining of ROS workspaces.
