problem with liblz4 install

[Mark Barton]

I am trying to compile a program that is requires 
liblz4 and gives an error that it cannot find 
-llz4. I tried to install lz4, lz4-dev and 
liblz4-1 using apt and got a message that the 
installed version is already the newest. I also 
tried adding the -1 to liblz4 and a compile but 
the issue remained

sudo apt install liblz4-1
Reading package lists... Done
Building dependency tree
Reading state information... Done
liblz4-1 is already the newest version (1.9.1-1).

I tried searching using find  but I could only 
find /usr/bin/lz4, no liblz4 or liblz4-1.

Not much on a google search either

Ubuntu 19.10

Any help is appreciated.
