BUG: Fix ThirdParty build shared lib CMake option names.

Remove the BUILD_SHARED_LIBS options for 3rd Party verdict library. The
variable being set was overwriting VTK's BUILD_SHARED_LIBS option because
it was being set to the same name.

Furthermore, although set, the variable is not used indeed anywhere in its
CMakeLists to build the library as static or shared.
