ROS_VERSION env variable not set at build time [linux-aarch64, osx-arm64]

Issue

In #49 we are trying to add the package foxglove_bridge which is a hybrid package that can be built both for ROS 1 and ROS 2. Which version is built depends on the ROS_VERSION environment variable, which is typically (when building with catkin/colcon) set by an env-hook of the package ros_environment (on which foxglove_bridge depends).

However, when building robostack for linux-aarch64 or osx-arm64 we noticed that the ROS_VERSION is not set, and we get the following error:

CMake Error at CMakeLists.txt:166 (message):
  ROS_VERSION environment variable must be 1 or 2

It seems that the env-hooks are not called and hence the ROS environment variables are not set. Maybe the easiest solution is to set these manually. E.g. for Humble:

export ROS_VERSION=2
export ROS_DISTRO=humble
export ROS_PYTHON_VERSION=3
