Stefan,
I have searched for a Library called Parola Fonts but to no avail! On Github, I did find and have downloaded a folder called MD_Parola_Fonts-master described as Fonts for Arduino library called MD_Parola.
This contains 4 files:
READSME.md
RomanCyrillic.h
SmallDigits.h
WideDigits.h
If I look in my MD_Parola library, there is a src folder which has a couple of .h files but mostly .cpp files. Is that where I would put the above files?
If I look at the examples folder, there is a folder called Parola_Fonts and that contains two files:
Parola_Fonts_data.h
Parola_Fonts.ino
I know the second file is the sketch, but I thought the first file would have been in the MD_Parola library but I cannot see it anywhere else.
I thought I would copy the SmallDigits.h file into the same folder as my sketch file but when I compile I get the following:

I'm obviously missing something fundamental but a cannot figure out what it is.
