• Seems like GIT_REPOSITORY https://github.com/PX4/Firmware.git is routed to https://github.com/PX4/PX4-Autopilot
• GIT_TAG "master" should be routed to "main" (considering https://github.com/PX4/PX4-Autopilot)
• Not sure if the patch is required with current autopilot version

CONFIGURE_COMMAND wget -q https://raw.githubusercontent.com/PX4/Firmware/master/msg/tools/uorb_rtps_message_ids.yaml -O uorb_rtps_message_ids.yaml
                    && patch --batch uorb_rtps_message_ids.yaml ${CMAKE_CURRENT_SOURCE_DIR}/config/uorb_rtps_message_ids.patch -o ./msg/tools/uorb_rtps_message_ids.yaml
