This is e.g. needed to be able to install snaps.

I thought lzo was something we wanted to remove like lzop
so is it a hard dependency for snaps ?

It depends on how the snaps are constructed. Some time ago, the default 
compression in snap was changed from xz to lzo to decrease execution 
time at the expense of binary size. Since then 'snap install' breaks 
with the message that unsquashfs is missing lzo support.
I tested installing some snaps and all of them had this issue.  After I 
built squashfs-tools with lzo support, installing the snaps worked. 
Most of them did not run (probably because my test image is largely 
x11-free), but for example the firefox snap ran very well.
