I think you're mixing up VERSION and SOVERSION.  The VERSION property dictates
what the library file is actually named: in this case, it's tied to the full
version number of the project, so the library is named libompl.so.0.9.2.  The
name of the library doesn't have anything to do with soname dependencies
however.  The SONAME property is set to the project's major version, which is
just 0.  You can check using objdump:

$ objdump -p /usr/lib64/libompl.so.0.9.2 |grep SONAME
  SONAME               libompl.so.0

This SONAME is what defines the ABI version, and won't change under this scheme
until the project bumps it major version number.  Major version changes usually
imply ABI changes anyway, but up until the major project version changes, any
dependencies won't need a rebuild when ompl is updated.
