Sounds like when you get that error, the Makefile target
isn't linking in libfltk.a (or -l fltk)
I don't know cmake well enough to tell you what's wrong
or why changing your app from Fl_Input -> Fl_Output breaks
the build, as both widgets are defined in the libfltk.a library
(or '-l fltk' link flag)
Sounds like either something is magically changing your makefile
between your working and non working build (you mentioned it builds
OK with cmake "using the GUI" in your OP, which might be doing
such magic generating makefiles on the fly) or a different make
target is being used when you switched Fl_Input <-> Fl_Output.
I'd suggest disabling .SILENT in your Makefile, or disabling
whatever is preventing the compile + link lines from being
printed in the 'make' output, as it's hiding the commands you
need to see to tell what's wrong.
Almost positive though that the error you're seeing is because
its not linking in liblftk.a (or using -l fltk).
