Unknown Target Error when running make px4_sitl gz_x500

[Lyndsey Mandelare]

The Error Message
ninja: error: unknown target 'gz_x500'
make: *** [Makefile:232: px4_sitl] Error 1

Setup

• Ubuntu: 20.04
• ROS: ROS2 foxy
• Ignition: Edifice
• latest pull from the PX4 Autopilot repo

Fixes attempted

• git clone PX4-simulation-ignition and build deb file. export IGN_GAZEBO_SYSTEM_PLUGIN_PATH=/usr/lib
• bash ./PX4-Autopilot/Tools/setup/ubuntu.sh. restart. make clean

If you are using the last pull, then the gz_bridge responsible for the connection with gazebo requires gazebo garden

# Find the gz_Transport library
find_package(gz-transport
	#REQUIRED COMPONENTS core
	NAMES
		#ignition-transport11 # IGN (Fortress and earlier) no longer supported
		gz-transport12
	#QUIET
)

therefore you need to upgrade gazebo

and PX4-Autopilot/Tools/setup/ubuntu.sh is outdated as it installs Fortress
