Both Debian and Ubuntu there is an excellent resources to answer these kinds of questions.

http://packages.debian.org/file:libXt.so

https://packages.ubuntu.com/search?searchon=contents&keywords=libXt.so&mode=exactfilename&suite=cosmic&arch=any

Compare the contents of 'libxt-dev' with those of it's dependency, 'libxt6'.
