package.xml in wrong directory (noetic on focal)

[otherwiseopen]

When installing this package in focal-noetic (in a docker image based on ros:noetic-robot), ROS does not work correctly, because the package places a package.xml into /opt/ros/noetic/share/

Checking the package contents shows:

this prevents ROS from working correctly.
The file should probably go into /opt/ros/noetic/share/rcdiscover/.

This is caused by ros-infrastructure/bloom#642

I will update it so that at least the package.xml is always installed to share...
In the meantime you could build rcdiscover yourself and install as deb with

cmake  -DCMAKE_INSTALL_PREFIX="/opt/ros/$ROS_DISTRO" -DCMAKE_PREFIX_PATH="/opt/ros/$ROS_DISTRO" -DCMAKE_BUILD_TYPE=Release ..
make package
sudo dpkg -i rcdiscover*.deb

which doesn't trigger this bug.

Sorry, has nothing to do with bloom GnuInstallDirs bug...
Fix coming up..

Fixed with rcdiscover 1.1.3
Blooming now, will take a while until this is rebuilt on the buildfarm and included in the next sync.
In the meantime you can build the deb yourself as described above.
