I copied the packages used in ROS to Windows, and wanted to use rosgenmsg to create custom defined messages. The commands:
>> folderpath='D:\matlab2020b\S_Ch\msgs\control_msgs';
>> rosgenmsg(folderpath)
But it has errors:
error in rosgenmsg (line 333)
No packages with '.msg' files found under D:\matlab2020b\S_Ch\msgs\control_msgs. Each message package directory must
contain a directory named 'msg' that then contains '.msg' files.
Howerer, there is a folder named ‘msg’ in it which contains some ‘.msg’ files.

Your .msg files appear to be inside a MSG directory inside of control_msgs_msg . The .msg files need to be directly in msg directory.

Hello Holden,
You are providing the "package" folder to rosgenmsg, when instead it requires the parent folder of that. This is because there are commonly multiple message packages, each with their own package folder, inside a single location. In this case, you should be providing the path to the "msgs" folder to rosgenmsg.
See here for more details on the expected folder structure.
