Matlab R2022b and R2023a installation did not contain CMake

I tried to create custom messages under R2022b and R2023a using the ros2genmsg command from the ROS Toolbox and received the following error:

Error using ros.internal.utilities.getCMakeBinaryPath

Unable to find CMake in your system. Please install CMake version 3.15.5 or higher and rerun the command.

I looked in the mentioned function ros.internal.utilities.getCMakeBinaryPath

There I saw that it searches at a certain folder for the CMake executable. But in my installation folder this directory does not exist.

aPath = fullfile(matlabroot,'bin',computer('arch'),'cmake','bin','cmake')

Although, there is a fallback solution, that does not work on Windows due to the command which.

[status, result] = system('which cmake')

I solved the problem by installing CMake manually and creating a symbolic link via the Windows command prompt with

mklink /D "C:\Program Files\MATLAB\<VERSION>\bin\win64\cmake" "C:\Program Files\CMake"

But I would like to know why my installed Matlab does not contain CMake and how I can possibly fix it.

[Jagadeesh Konakalla]

Can you please install MATLAB Coder and try the rosgenmsg and ros2genmsg workflows ?

[Kevin]

After the installation of MATLAB Coder both workflows work.

I tested them with the corresponding examples.

Thanks for the support.
