ros2 pkg list show cmake packages

Hello,

I have a ros2 workspace with both ament and cmake packages.

The command "ros2 pkg list" does not show cmake packages that I have built and installed. It only shows ament packages. How do I get it to list cmake packages?

For the cmake packages, in package.xml, I use package version 3 and set buildtool_depend, buildtool_export_depend, and export/build_type to cmake.

I am assuming that is problem connected with failure of "ros2 launch package launch-file" failing on cmake packages. Have not tested the xacro "$(find package)" on cmake packages, but am assuming that would fail too.

In order to be detectable as an installed ROS package your package should do two things (which ament_cmake packages does automatically in the ament_package() function):

install an empty marker file named ${PROJECT_NAME} to share/ament_index/resource_index(see https://github.com/ament/ament_cmake/... and https://github.com/ament/ament_cmake/...) and
install the package.xml file to share/${PROJECT_NAME}(see https://github.com/ament/ament_cmake/...) which might not strictly be necessary for your use case but your package should do anyway.

In contrast to ROS 1 the presence of the marker file allows for more efficient queries what packages are installed and where.

Thanks for the fast response. I installed the the empty marker file to the directory ament_index/resource_index/packages/.
