[R-sig-Debian] How to install libisl.so.19 on chromebook?

[Luigi Marongiu]

Thank you, it looks like I have already libisl:
```
apt search libisl
Sorting... Done
Full Text Search... Done
libisl-dbg/oldstable 0.18-1 amd64
  manipulating sets and relations of integer points bounded by linear
constraints

libisl-dev/oldstable 0.18-1 amd64
  manipulating sets and relations of integer points bounded by linear
constraints

libisl15/oldstable,now 0.18-1 amd64 [installed,automatic]
  manipulating sets and relations of integer points bounded by linear
constraints

libisl19/now 0.19-1 amd64 [installed,local]
  manipulating sets and relations of integer points bounded by linear
constraints
```
thus the problem must be with the installation step: I should tell the
compiler to look for libisl19 instead of  libisl.so.19...
