I don't think coinstallability of multiple versions of the _static_
library in the same directory is needed, anyway. Or you would then
also need to version the corresponding include files.

At any given time, in a given directory tree, you'll always want
to have a matching triplet of liblwgeom.h, liblwgeom.a
and liblwgeom.so files.

Of course it'd still be useful to properly support --prefix to
determine where those triplets are installed:
