Correct.  This allows installation into $prefix/lib so that someone with
LD_LIBRARY_PATH=$prefix/lib set can run without RPATHs.  Also the version
number belongs in the library name rather than the soname because VTK's
version numbers do not follow any dynamic loader conventions for ABI
compatibility.  Each major.minor version is its own distinct interface.
