lcov code breaks build on Mac, Windows

[rotu]

Description

The build is failing for cyclonedds and other packages on Mac and Windows due to missing lcov.

Expected Behavior

The build should not break. Either lcov should not be run by default or in its absence, the build should not fail.

Actual Behavior

https://github.com/ros2/rmw_cyclonedds/runs/985853020#step:5:5529
https://github.com/ros2/rmw_cyclonedds/runs/985853090#step:5:5343

To Reproduce

https://github.com/ros2/rmw_cyclonedds/actions/runs/208880070/workflow

System (please complete the following information)

• OS: macOS-latest, windows-latest
• ROS 2 Distro: rolling

Additional context

It looks like some attempt was made for this error not to be fatal by passing an ignoreReturnCode option. Unfortunately, this doesn't appear to work as intended.

@thomas-moulard could you please take a look at this? I'm having trouble even getting coverage working on Linux, so I'm not sure if I'm doing it right.

Just as a note, #712 disabled colcon-lcov-result on Windows.
