# - Find MED library
# Find the MED includes and library

#  MED_INCLUDE_DIR, where to find med.h
#  MED_INCLUDE_DIRS, where to find med.h file, concatenated with other include dirs from HDF5 and MPI (if parallel)
#  MED_LIBRARIES, libraries to link against to use MED. (including HDF5 and MPI if parallel)
#  MED_FOUND, If false, do not try to use MED.
# also defined, but not for general use are
#  MED_LIBRARY, the med library.
#  MEDC_LIBRARY, the medC library
