Hello.

You may use dynamic loading of those libraries.
So no need of xxx.dev packages.

Take a look here:
https://github.com/fredvs/dynx

And here a fpGUI application using those dynamic loaded libraries:

Why not fix readme?

[Fred vS]

IMHO, it is not a fpGUI problem.
You should advice this to fpc mailing-list or fpc-bug tracker.

This readme is on this github at the root.

Thank you for reporting this Alexey-T - I don't always keep track of the latest Linux distro changes. They just love to break backwards compatibility. :-/ The new package names are the same as the old ones, just all lower-case. I have updated the README.txt file in both the maint and develop branches.
