Hello,
This week I tried to install the stable version of MATLAB R2021b in windows, but found that rosgenmsg could not find CMake. But there is no problem in ubuntu system.
>> !where cmake
C:\Program Files\CMake\bin\cmake.exe
>> !cmake --version
cmake version 3.21.3
CMake suite maintained and supported by Kitware (kitware.com/cmake).
>> folderpath = "C:\Users\xinxi\Documents\MATLAB\***"
folderpath =
"C:\Users\xinxi\Documents\MATLAB\***"
>> rosgenmsg(folderpath)

My computer also has MATLAB R2021a installed. I tried to run rosgenmsg but without any errors. I have before also used the preview version of R2021b, and there was no problem.

Which CMake version do you have installed on the Windows machine? And did you add it to you Windows PATH environment variables, and add CMAKE_PREFIX_PATH to your environment variables ?

I looked at the code for ros.internal.utilities.getCMakeBinaryPath() . It looks to me as if it cannot work on MS Windows. I have reported the problem to Mathworks.

this workaround does not work for me.
After installing msys and configuring PATH as described, the initial error is gone, and cmake can be found.
colcon however fails to build.
Below is my output when running the official example 'ROS2CustomMessagesExample.mlx' for MATLAB R2021b on Windows 10.
Any thoughts on this?
I have to admit, that I am rather disappointed, that rather simple and once running features of the toolbox are broken with a new release and that seemingly nobody even tested this on all platforms before the release.

Sorry about the late response and the trouble caused by this issue. An update that addressed this issue has been released, please feel free to update your MATLAB to the latest version if you haven't done so.
This error message seems not related to the cmake issue. We've seen this before when python virtual environment used by MATLAB got corrupted.
Could you please recreate the python virtual environment using the following command and then follow the example to generate ROS 2 custom messages again?
>> ros.ros2.internal.createOrGetLocalPython(true)
Thanks,
Josh
