libcsnd-dev 1:6.18.1+dfsg-1 (ppc64el binary) in ubuntu lunar

 This package contains the development files needed to build programs
 using the C++ bindings to the Csound library. It also includes the
 development symlink for the Lua module, but you have to manually
 install liblua5.1-luacsnd for that to work.
 .
 For more information on Csound, see the csound package.
