[vtkusers] VTK and Trilinos

[Truman Ellis]

I am using a CMake build system to build my code with Trilinos, and
everything works just fine. I started trying to additionally link with
VTK, which also assumes a CMake build system. I have test codes which
only link to VTK, and my current code only links to Trilinos. But when I
try to make my code link to both VTK and Trilinos, they don't seem to
play well together. For some reason, when I link to both VTK and
Trilinos, I get errors of the type:
../../libCamellia.so: undefined reference to
`Epetra_MpiComm::Epetra_MpiComm(ompi_communicator_t*)'

(We have a library called Camellia and several drivers such as
NavierStokes below)

The verbose makefile output that generated this error is:

I've messed around with this for two days now, and I can't seem to
figure out what is going wrong.

Any ideas?
