ROS2 Humble and Gazebo Garden are installed in Linux 22.04 aarch64/arm64 (VM on MAC M1)
Following https://github.com/gazebosim/ros_gz/tree/humble , Build from Source. rosdep and colcon build fail.

Failure to do so may result in build failures or undefined behavior at run time. If the overridden package is used by another package in any underlay, then the overriding package in the overlay must be API and ABI compatible or undefined behavior at run time may occur.
If you understand the risks and want to override a package anyways, add the following to the command line: --allow-overriding ros_ign_bridge ros_ign_gazebo ros_ign_gazebo_demos ros_ign_image ros_ign_interfaces
This may be promoted to an error in a future release of colcon-override-check.

CMake Error at CMakeLists.txt:28 (find_package):
By not providing "Findignition-transport10.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"ignition-transport10", but CMake did not find one.
Could not find a package configuration file provided by "ignition-transport10" with any of the following names:
ignition-transport10Config.cmake
ignition-transport10-config.cmake
Add the installation prefix of "ignition-transport10" to CMAKE_PREFIX_PATH or set "ignition-transport10_DIR" to a directory containing one of the above files. If "ignition-transport10" provides a separate development
package or SDK, be sure it has been installed.

I located this in answers.gazebo.org, installed the cmake-gui.exe but unable to determine the necessary paths. Where is path to ignition-transport10_DIR?
Found Solution now, I suggest you use cmake-gui.exe ,you will find at C:\Program Files\CMake\bin if you install on that directory
run cmake-gui.exe select path source code and select path to build run configure 1 time you will found error same edit path ignition-cmake0_DIR to gz-ws/ign-cmake/build/install/Release/lib/cmake/ignition-cmake0 Run again Done !!
Appreciate any assistance
