The export_library_dependencies command should never be used in new
code for any reason.  In fact CMake 3.0 will introduce a CMake Policy
that will complain about calls to the command.  The only reason the
command still exists is to support old code.

This is a known limitation of export_library_dependencies and is one
reason it was replaced by install(EXPORT).

The dependencies are expressed between imported library targets by
their logical name, but each has an IMPORTED_LOCATION property set
to the proper file name with the -6.0 suffix.  You just need to make
sure that VTK's are imported along with yours.

See the tutorials here:


If you're writing a project that does find_package(VTK), links to
VTK_LIBRARIES in your own targets, and then install(EXPORT)s them,
then in your <package>Config.cmake file that loads the targets
file produced by install(EXPORT)s you need to find_package(VTK)
too in order to get VTK's imported targets to satisfy dependencies.
