On a fresh Ubuntu machine, I am looking at the install and build instructions here, 
https://github.com/csound/csound/blob/develop/BUILD.md 

If FLTK is being deprecated, can I simply leave that out from the apt install? 
I'm not sure about the libstk0-dev I've turned source code on for the repositary. 


$ sudo apt-get install cmake libsndfile1-dev libasound2-dev libjack-dev portaudio19-dev
libportmidi-dev libpulse-dev swig liblua5.1-0-dev default-jdk libfltk1.1-dev
libfluidsynth-dev liblo-dev fluid ladspa-sdk libpng-dev dssi-dev libstk0-dev libgmm++-dev
bison flex libportsmf-dev libeigen3-dev libcunit1-dev gettext libsamplerate0-dev

Package libstk0-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Thanks for this.

From my perspective, FLTK and libstk0 dependencies can be left out.

The opcodes using these are in the Csound plugins repository. They need to
be ported to Csound 7, but since that repo has never had a maintainer, it’s
unlikely that they will be available any time soon. Same thing for fluidsynth,
but since that one is more useful maybe someone will port it (porting is
just changing a few lines of code, so very simple).

Also libfluidsynth and libpneg can be left out - the opcodes that use these are not part of the main Csound repo either.
