While installing ROS 2 on MacOS, I encountered some problem with Colcon. It seems that it uses the wrong Cmake path.
Running
colcon build --symlink-install --packages-skip-by-dep python_qt_binding
causes the following error:make: /opt/homebrew/Cellar/cmake/3.25.0/bin/cmake: No such file or directory
Full Output:

The correct Cmake path would be:
>>> which cmake /opt/homebrew/Cellar/cmake/3.26.0/bin/cmake
Setting the correct path like this
set -x CMAKE_COMMAND /opt/homebrew/Cellar/cmake/3.26.0/bin
didn't have any effect.
