[satzguyz]

Issue Description:
Unable to start gz_x500 or gazebo simulation targets, in latest version (1.13.3) of px4 using Ubuntu 22 OS as development environment. But jmavsim works as usual.

Terminal Command:
make px4_sitl gz_x500

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

Detailed Description:
OS Version : Ubuntu 22
Machine Capacity: intel i9 64 bit machine

Steps to reproduce:

1. clone the master codebase
   git clone https://github.com/PX4/PX4-Autopilot.git --recursive

2. Checkout the v1.13.3 and update submodules
   git switch -c v1.13.3
   make submodulesclean

3. Install dependent packages
   bash ./Tools/setup/ubuntu.sh

4. Compile for gazebo gz_x500 Target
   make px4_sitl gz_x500

@satzguyz The issue template was there to encourage you to put down the details as much as possible.

Please provide more information on your system. e.g. what your operating system version is, the full log of your terminal and what simulator is installed and what is not installed.

For example, Ubuntu 22.04 primarily supports Gazebo (gz) but not Gazebo classic(gazebo-classic). With the limited information you have provided, it is hard to reproduce the problem you are running into.

I am new to this. Kindly point me the template reference which I can follow in Future. I tried to provide more details as possible. Let me know if it needs more details.

@satzguyz I see the issue there. v1.13.3 does not support the new gazebo, which is what you are trying to run with gz.

If you want to use the new gazebo, you should use the master branch of PX4 (don't checkout to v1.13.3)

@satzguyz In case you are interested, here's how I got the v1.13.2 to work with Ignition Gazebo 6:

1. Update ignition simulation submodule to include this change: Gazebo6 Auterion/px4-simulation-ignition#26
2. Remove the force to use gazebo 5 for ignition from this change: Force ignition to use version 5 (edifice) in sitl run #19225

Then, make px4_sitl ignition should work, if you have the ignition installed.

I did this to test if the current ignition (somehow different from old ignition "edifice" that is now retired) works with v1.13.2. And seems like changing that dependency in submodule & changing the script does the job of using the gazebo 6 ignition (whatever it means).
