That is not the correct package name as it is a _file name_.

Use eg

 https://packages.debian.org/

to search (go to Search the contents of packages) or search directly via

 apt search libisl

which will lead you to packages

 libisl-dev
 libisl22           # on the release I run on Ubuntu right now

with a major name reflecting the current release. For an older version I find
the package search above useful, there are other pages too.

Hope this helps,  Dirk
