In this case, Java cannot find VTVTKhared (dynamic) libraries. Those are
actually not Java but C++ libraries. Look where you have
lilibvtkCommonJavao and sisimilaribraries. This could be 'bin'
subdirectory of you VTVTKuild directory. Add that directory to you
LDLDIBRARY_PATH variable. AlAlternativelyou can specify it as
'jajavaibrary.path' parameter when running JVJVM 
jajavaDjDjavaibrary.path=some_didirectoryone
You can spspecifyore then one directory if you separate them by a colon
(same convention as used by LDLDIBRARY_PATH).

This is a directory there Java looks for shared libraries (on PC those
will be DLDLLs

See above, this is just a core of a library name, in this case
lilibvtkCommonJavao.
