libvterm-dev binary package in Ubuntu Oracular amd64

 An abstract C99 library which implements a VT220 or xterm-like terminal
 emulator. It doesn't use any particular graphics toolkit or output
 system, instead it invokes callback function pointers that its embedding
 program should provide it to draw on its behalf. It avoids calling
 malloc() during normal running state, allowing it to be used in embedded
 kernel situations.
 .
 This package contains the header files and libraries needed for developing
 with libvterm.
