Cannot link if built with OPTION_PRINT_SUPPORT=OFF

[darealshinji]

Describe the bug
I'm getting linking errors when I had build libfltk with "cmake -DOPTION_PRINT_SUPPORT=OFF":

/usr/bin/ld: /home/[...]/usr/lib/libfltk.a(Fl_Printer.cxx.o):(.data.rel.ro._ZTV25Fl_PostScript_File_Device[_ZTV25Fl_PostScript_File_Device]+0x10): undefined reference to `Fl_PostScript_File_Device::end_current()'
/usr/bin/ld: /home/[...]/usr/lib/libfltk.a(Fl_Printer.cxx.o):(.data.rel.ro._ZTV25Fl_PostScript_File_Device[_ZTV25Fl_PostScript_File_Device]+0x18): undefined reference to `Fl_PostScript_File_Device::set_current()'
collect2: error: ld returned 1 exit status

To Reproduce
I need to build fluid first since it requires print support and OpenGL.
After that I can build FLTK with most features disabled.

Expected behavior
Make it possible to build with "-DOPTION_PRINT_SUPPORT=OFF", since that is an option in cmake.

Confirmed: no matter whether I build with or without Wayland (note: Wayland-only not tested), the build fails when linking fluid, fltk-options, or any other test program. Example CMake and configure commands:

cmake -DOPTION_PRINT_SUPPORT=OFF ..
./configure --disable-print

Both fail with the same error message as reported by @darealshinji

@ManoloFLTK: can you please take a look? I'm not really familiar with this printing stuff and what to remove/disable (and what to keep) when print support is switched off. TIA.

[ManoloFLTK]

That should be fixed with the commit mentioned above. @darealshinji : Please, close issue if you confirm.

This works, thanks. Now I see that the same happens with SVG disabled:

/usr/bin/ld: CMakeFiles/fluid-lib.dir/Fluid_Image.cxx.o: in function `Fluid_Image::write_static(Fd_Code_Writer&, int)':
Fluid_Image.cxx:(.text._ZN11Fluid_Image12write_staticER14Fd_Code_Writeri+0x38e): undefined reference to `Fl_SVG_Image::resize(int, int)'
collect2: error: ld returned 1 exit status

Fluid indeed needs Fl_SVG_Image code at line ~220. However I'm closing this as the issue was solved.

@darealshinji Commit c606914 should also allow to build with SVG disabled.

@ManoloFLTK Great solution(s), I wouldn't have had an idea where to look. Thanks.
