Compiling: Invalid library found... no headers files (.h)

[Modesty]

Hi

Runing WIN11

code compiles, but this type of error:

Invalid library found in D:\Gdrive\NAS\Arduino\libraries\CayenneMQTT-1.3.0: no headers files (.h) found in D:\Gdrive\NAS\Arduino\libraries\CayenneMQTT-1.3.0

What is this, something I need to do?

Please post the full sketch that your are compiling, using < CODE/ > tags when you do

Which Arduino board are you using and which version of the IDE ?

Hi @UKHeliBob

Thanks for answer me. I found the answer, library CayenneMQTT vas not installed... my bad.

@Modesty

CayenneMQTT vas not installed

Not properly installed would be a better description.
You obviously don't get the message for all the libraries that you did not install.

I have seen this message, when there were empty directories in the library folder,
that somehow ended there.

Yes yes, I probably did some fiddling....
