[Bug] Error with running sims on Gazebo models: ninja: error: unknown target 'gz_x500' make: *** [Makefile:232: px4_sitl] Error 1

Describe the bug

I am trying to run make px4_sitl gz_x500 or make px4_sitl gz_x500_depth, but there seems to be an issue of ninja: error: unknown target 'gz_x500'. I have tried other models also and none of them seem to be working. I made sure to restart at all the spots mentioned on the official documentation for the setup of ROS2 with PX4 Autopilot.

Full Log:
