cmake binary execute error on windows 11

[knmcguire]

• OS: Windows 11
• ROS 2 install: Rolling by the new windows binary install with pixi
• MSvc build environment: 2019 (did had to install as from these instructions)
• Rust ROS2 install: these instructions with adding the additional packages to the ROS2 pixi environment by conda and pypi.

When I follow these instructions to install ROS2-rust, unique_identifier_msgs gets an error.

  Generating Rust code for ROS interfaces
  'C:\dev\ws\rust_ros\install\share\rosidl_generator_rs\cmake\..\..\..\lib\rosidl_generator_rs\rosidl_generator_rs' is not recognized as an internal or external command,
  operable program or batch file.

stdout.log

This is due to several issues I think:

1. lib is called Lib with capital in windows. It should not be case sensitive but you never know...
2. the backtracking might not work properly? It does go to the right location though
3. rosidl_generator_rs is a python script but windows doesn't like executing it as a standalone binary file

Probably number 3 is quite likely, so perhaps fix needs to be made in the custom_command.cmake file.
