Just stumbled across the same thing. It also happens with 3.10.1. The
problem is that on Debian/Ubuntu FindMPI.cmake populates
MPI_INCLUDE_PATH with
/usr/lib/openmpi/include;/usr/lib/openmpi/include/openmpi. The whole VTK
source tree, however, assumes that this variable only contains a single
entry. E.g., the following shows up a lot in the CMakeLists.txt files:

INCLUDE_DIRECTORIES("${MPI_INCLUDE_PATH}")

Due to the quoting the list is interpreted as a single string and
-I"/usr/lib/openmpi/include;/usr/lib/openmpi/include" just doesn't make
much sense...

The cure is simple, issue the following in the build tree (provided you
chose openmpi to be your default MPI implementation in the alternatives
system):

cmake -DMPI_INCLUDE_PATH=/usr/include/openmpi
-DMPI_LIBRARY=/usr/lib/libmpi.so
-DMPI_EXTRA_LIBRARY=/usr/lib/libmpi_cxx.so .


Of course, this issue should be also fixed either in FindMPI.cmake or in
the VTK sources.
